ARM: SoC fixes for -rc1
A batch of fixes that have come in during the merge window. Some of them are defconfig updates for things that have now landed, some errata additions and a few general scattered fixes. There's also a qcom DT update that adds support for SATA on AP148, and basic support for Sony Xperia Z1 and CM-QS600 platforms that seemed isolated enough that we could merge it even if it's late. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJURCIHAAoJEIwa5zzehBx3Y9wP/1u9tcUjJs+AXD5RSRvabd50 sN2oDk6cg3NzIvy9gzpmDXpHq9T0k/ce37a/NW/Rvyhq17u+g2EoC4XfR/8xeWAe uijbWzqmfhONSAPXc9+fwqjtdNKBj7e+4mtRSsdvMjduu6bpqAvhKEtRhCQeaKbv COjERAvDviAtW7Bpn/8j1ZVYJ0Yng5C7lT00GKNGXoGJ8aA9E4Yu3fhzBPitpkhX deLBHo7Ku32J9umoSqViQ5Ba25wCDESPPjLOYmKScj0pTlduywKerW4i5Bk8Pbo2 ZJ/sA/glpSXqksAjbcdhzn2jntVz6a2e1ur7fibS+h73q2fRx3Gr8O02TiRl8nwZ VlbOFq/lovn+fFu7as5hoM5F4f/agHLuQBKYnuZvJ5OoXDO0vlo1+smEWw/4ta+f GVVxMOPcRaEiOoez+iJxQzoQGNFz3D5Ei9UMX6xkwpixBR3kx/m5WYhP/IO+qx4/ Nkn0yAoRYfgx3zclqAhmqHkvbvcKrnYnHa4mV0xhhh6Mm0QOwZcKdfXCrQqrW8sm Jr5Dh6Ehha+i9Hp/eabVf/Tfr8BibSa/FYoMaP9pj++Ol5jJlYcwa+59jrnJ42t2 GZEQKuWhl3DFCrMA/DPg968eNPOVunS039BJ0Se29Y3u6ulZSkl473OicueNJSEd XNGDyuHhhtBVJzQjzJ3z =V3Rv -----END PGP SIGNATURE----- Merge tag 'arm-soc-fixes-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC fixes from Olof Johansson: "A batch of fixes that have come in during the merge window.

Merge git://git.infradead.org/users/eparis/audit
Pull audit updates from Eric Paris: "So this change across a whole bunch of arches really solves one basic problem. We want to audit when seccomp is killing a process. seccomp hooks in before the audit syscall entry code. audit_syscall_entry took as an argument the arch of the given syscall. Since the arch is part of what makes a syscall number meaningful it's an important part of the record, but it isn't available when seccomp shoots the syscall... For most arch's we have a better way to get the arch (syscall_get_arch) So the solution was two fold: Implement syscall_get_arch() everywhere there is audit which didn't have it. Use syscall_get_arch() in the seccomp audit code. Having syscall_get_arch() everywhere meant it was a useless flag on the stack and we could get rid of it for the typical syscall entry. The other changes inside the audit system aren't grand, fixed some records that had invalid spaces. Better locking around the task comm field. Removing some dead functions and structs. Make some things static. Really minor stuff" * git://git.infradead.org/users/eparis/audit: (31 commits) audit: rename audit_log_remove_rule to disambiguate for trees audit: cull redundancy in audit_rule_change audit: WARN if audit_rule_change called illegally audit: put rule existence check in canonical order next: openrisc: Fix build audit: get comm using lock to avoid race in string printing audit: remove open_arg() function that is never used audit: correct AUDIT_GET_FEATURE return message type audit: set nlmsg_len for multicast messages. audit: use union for audit_field values since they are mutually exclusive audit: invalid op= values for rules audit: use atomic_t to simplify audit_serial() kernel/audit.c: use ARRAY_SIZE instead of sizeof/sizeof[0] audit: reduce scope of audit_log_fcaps audit: reduce scope of audit_net_id audit: arm64: Remove the audit arch argument to audit_syscall_entry arm64: audit: Add audit hook in syscall_trace_enter/exit() audit: x86: drop arch from __audit_syscall_entry() interface sparc: implement is_32bit_task sparc: properly conditionalize use of TIF_32BIT ... |

ARM: dts: Explicitly set dr_mode on exynos Peach boards
In case the optional dr_mode property isn't set in the dwc3 nodes the the controller will go into OTG mode if both USB host and USB gadget functionality are enabled in the kernel configuration. Unfortunately this results in USB not working on exynos5420-peach-pit and exynos5800-peach-pi with such a kernel configuration unless manually change the mode. To resolve that explicitly configure the dual role mode as host.

arm/arm64: KVM: Fix BE accesses to GICv2 EISR and ELRSR regs
The EIRSR and ELRSR registers are 32-bit registers on GICv2, and we store these as an array of two such registers on the vgic vcpu struct. However, we access them as a single 64-bit value or as a bitmap pointer in the generic vgic code, which breaks BE support. Instead, store them as u64 values on the vgic structure and do the word-swapping in the assembly code, which already handles the byte order for BE systems.

Merge branch 'for-3.18-consistent-ops' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu consistent-ops changes from Tejun Heo: "Way back, before the current percpu allocator was implemented, static and dynamic percpu memory areas were allocated and handled separately and had their own accessors. The distinction has been gone for many years now; however, the now duplicate two sets of accessors remained with the pointer based ones - this_cpu_*() - evolving various other operations over time. During the process, we also accumulated other inconsistent operations. This pull request contains Christoph's patches to clean up the duplicate accessor situation. __get_cpu_var() uses are replaced with with this_cpu_ptr() and __this_cpu_ptr() with raw_cpu_ptr(). Unfortunately, the former sometimes is tricky thanks to C being a bit messy with the distinction between lvalues and pointers, which led to a rather ugly solution for cpumask_var_t involving the introduction of this_cpu_cpumask_var_ptr(). This converts most of the uses but not all. Christoph will follow up with the remaining conversions in this merge window and hopefully remove the obsolete accessors" * 'for-3.18-consistent-ops' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: (38 commits) irqchip: Properly fetch the per cpu offset percpu: Resolve ambiguities in __get_cpu_var/cpumask_var_t -fix ia64: sn_nodepda cannot be assigned to after this_cpu conversion.

The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers. This tag contains a bit more arch code than I usually take due to some OMAP2+ changes. Additionally it contains the restart notifier handlers which are merged as a dependency into several trees. The PXA changes are the only messy part. Due to having a stable tree I had to revert one patch and follow up with one more fix near the tip of this tag. Some dead code is introduced but it will soon become live code after 3.18-rc1 is released as the rest of the PXA family is converted over to the common clock framework. Another trend in this tag is that multiple vendors have started to push the complexity of changing their CPU frequency into the clock driver, whereas this used to be done in CPUfreq drivers. Changes to the clk core include a generic gpio-clock type and a clk_set_phase() function added to the top-level clk.h api. Due to some confusion on the fbdev mailing list the kernel boot parameters documentation was updated to further explain the clk_ignore_unused parameter, which is often required by users of the simplefb driver. Finally some fixes to the locking around the clock debugfs stuff was done to prevent deadlocks when interacting with other subsystems. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJUMu8gAAoJEDqPOy9afJhJ+GwP/3aU1PzhEPooZ3sZ5hkhmRYc RTzNZAODuOGbGnAiNQcr8XW3LJ6wKz5TSzzUC8IQkTcYM1Tsc7s5B6v+nMOkR2Jh sfrlnDEV/dsW9/3QADFuBowCaZdsaZnHn96RDhTmyDlPjh4HRR2k8ITT+TREbFrd cHDWy4QnI0u4NzhKtitvgW2770HyBpr31v5IdoRhVi5whoiBNL49BPwhwDWhwZVe w6qvc0jV8FK9Ra/Q7Vw6r3tiKkpO/upqVFDrsO831mp2qDcQvtOgNW9H2fjcobaX 3/KCbs1TZs39e71RsEGwCvmCudXkTgO1wUJ86MuCLHeb2o78Vx8EYie02/RApTOJ 0KGR+kFouggy2naeH8pXiTZk2HWMCbut6NQ1+AVbea5Em7hgHbYaQN71wVFKR4L7 QL+TugrIg81fGWSvxoTo6fsbEiKOUdhXvHFWP5etKHL+Ll+7ku05ojHLOZgEEwTf zFWSSF4XSFQtuQD1gup0pSfoLs6qVR57l8FsrxfRPK9jGttg5z1wyNkY+585ptim eyTn4mkvkx9t9Sx47VRj9WPcPr2SW1w8lTMw1WqKfHG7AEUJHHkRQThQmiU82b47 dTls4BBZ6sVZ8wj0V4zvnvbmtdYohOmBqNDEYx+a0dzPKstcAJyZgcjWBc13zds4 rIKKxhiU7jGWH4qnJLrx =w2rN -----END PGP SIGNATURE----- Merge tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux Pull clock tree updates from Mike Turquette: "The clk tree changes for 3.18 are dominated by clock drivers.

arm/arm64: KVM: Ensure memslots are within KVM_PHYS_SIZE
When creating or moving a memslot, make sure the IPA space is within the addressable range of the guest. Otherwise, user space can create too large a memslot and KVM would try to access potentially unallocated page table entries when inserting entries in the Stage-2 page tables.

arm64: KVM: Implement 48 VA support for KVM EL2 and Stage-2
This patch adds the necessary support for all host kernel PGSIZE and VA_SPACE configuration options for both EL2 and the Stage-2 page tables. However, for 40bit and 42bit PARange systems, the architecture mandates that VTCR_EL2.SL0 is maximum 1, resulting in fewer levels of stage-2 pagge tables than levels of host kernel page tables. At the same time, systems with a PARange > 42bit, we limit the IPA range by always setting VTCR_EL2.T0SZ to 24. To solve the situation with different levels of page tables for Stage-2 translation than the host kernel page tables, we allocate a dummy PGD with pointers to our actual inital level Stage-2 page table, in order for us to reuse the kernel pgtable manipulation primitives. Reproducing all these in KVM does not look pretty and unnecessarily complicates the 32-bit side. Systems with a PARange < 40bits are not yet supported. [ I have reworked this patch from its original form submitted by Jungseok to take the architecture constraints into consideration. There were too many changes from the original patch for me to preserve the authorship. Thanks to Catalin Marinas for his help in figuring out a good solution to this challenge. I have also fixed various bugs and missing error code handling from the original patch. - Christoffer ] Reviewed-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Jungseok Lee <jungseoklee85@gmail.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org> |

ARM: replace strnicmp with strncasecmp
The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

arm/arm64: KVM: map MMIO regions at creation time
There is really no point in faulting in memory regions page by page if they are not backed by demand paged system RAM but by a linear passthrough mapping of a host MMIO region. So instead, detect such regions at setup time and install the mappings for the backing all at once.

ARM: kvm: define PAGE_S2_DEVICE as read-only by default
Now that we support read-only memslots, we need to make sure that pass-through device mappings are not mapped writable if the guest has requested them to be read-only. The existing implementation already honours this by calling kvm_set_s2pte_writable() on the new pte in case of writable mappings, so all we need to do is define the default pgprot_t value used for devices to be PTE_S2_RDONLY.

common: dma-mapping: introduce common remapping functions
For architectures without coherent DMA, memory for DMA may need to be remapped with coherent attributes. Factor out the the remapping code from arm and put it in a common location to reduce code duplication. As part of this, the arm APIs are now migrated away from ioremap_page_range to the common APIs which use map_vm_area for remapping. This should be an equivalent change and using map_vm_area is more correct as ioremap_page_range is intended to bring in io addresses into the cpu space and not regular kernel managed memory.

ACPI and power management updates for 3.18-rc1
- Rework the handling of wakeup IRQs by the IRQ core such that
all of them will be switched over to "wakeup" mode in
suspend_device_irqs() and in that mode the first interrupt
will abort system suspend in progress or wake up the system
if already in suspend-to-idle (or equivalent) without executing
any interrupt handlers. Among other things that eliminates the
wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
flag with interrupts which don't really need it and should not
use it (Thomas Gleixner and Rafael J Wysocki).
- Switch over ACPI to handling wakeup interrupts with the help
of the new mechanism introduced by the above IRQ core rework
(Rafael J Wysocki).
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during
enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in
the METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot
(or after resume from system suspend) and rework the ACPI Smart
Battery Subsystem (SBS) driver to work correctly with Apple
platforms (Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
code, adding support for 133MHz I2C source clock on Intel Baytrail
to it and making it avoid using UART RTS override with Auto Flow
Control (Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
Sudip Mukherjee, Yijing Wang, and Zhang Rui).
- cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
Rasmus Villemoes).
- cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
change among other things), ppc-corenet, powernv (Viresh Kumar,
Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
- cpuidle support for DT-based idle states infrastructure, new
ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
Rasmus Villemoes).
- ARM big.LITTLE cpuidle driver updates: support for DT-based
initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
Kevin Hilman).
- Rework of the test_suspend kernel command line argument and
a new trace event for console resume (Srinivas Pandruvada,
Todd E Brandt).
- Second attempt to optimize swsusp_free() (hibernation core) to
make it avoid going through all PFNs which may be way too slow on
some systems (Joerg Roedel).
- devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
- rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
- PM core fix related to clock management (Geert Uytterhoeven).
- PM core's sysfs code cleanup (Johannes Berg).

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).
Specifics:
- Rework the handling of wakeup IRQs by the IRQ core such that all of
them will be switched over to "wakeup" mode in suspend_device_irqs()
and in that mode the first interrupt will abort system suspend in
progress or wake up the system if already in suspend-to-idle (or
equivalent) without executing any interrupt handlers. Among other
things that eliminates the wakeup-related motivation to use the
IRQF_NO_SUSPEND interrupt flag with interrupts which don't really
need it and should not use it (Thomas Gleixner and Rafael Wysocki)
- Switch over ACPI to handling wakeup interrupts with the help of the
new mechanism introduced by the above IRQ core rework (Rafael Wysocki)
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during enumeration
(Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in the
METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot (or
after resume from system suspend) and rework the ACPI Smart Battery
Subsystem (SBS) driver to work correctly with Apple platforms
(Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code,
adding support for 133MHz I2C source clock on Intel Baytrail to it
and making it avoid using UART RTS override with Auto Flow Control
(Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak)
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin)
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
Sudip Mukherjee, Yijing Wang, and Zhang Rui)
- cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
Rasmus Villemoes)
- cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change
among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U
Murthy, Shilpasri G Bhat, Lucas Stach)
- cpuidle support for DT-based idle states infrastructure, new ARM64
cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus
Villemoes)
- ARM big.LITTLE cpuidle driver updates: support for DT-based
initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
Kevin Hilman)
- Rework of the test_suspend kernel command line argument and a new
trace event for console resume (Srinivas Pandruvada, Todd E Brandt)
- Second attempt to optimize swsusp_free() (hibernation core) to make
it avoid going through all PFNs which may be way too slow on some
systems (Joerg Roedel)
- devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
- rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry
update in MAINTAINERS (Heiko Stübner, Kevin Hilman)
- PM core fix related to clock management (Geert Uytterhoeven)
- PM core's sysfs code cleanup (Johannes Berg)"

This is the bulk of GPIO changes for the v3.18 development
cycle:
- Increase the default ARCH_NR_GPIO from 256 to 512. This
was done to avoid having a custom <asm/gpio.h> header for
the x86 architecture - GPIO is custom and complicated
enough as it is already! We want to move to a radix to
store the descriptors going forward, and finally get rid
of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated
by Abdoulaye Berthe. It is not accepted by the system that
the removal of a GPIO chip fails during e.g. reboot or
shutdown, and therefore the return value has now painfully
been refactored away. For special cases like GPIO expanders
on a hot-pluggable bus like USB, we may later add some
gpiochip_try_remove() call, but for the cases we have now,
return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI
GPIO library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle
also threaded, nested interrupts and set up the parent IRQ
correctly. Switch STMPE and TC3589x drivers to use this
registration method.
- Add a .irq_not_threaded flag to the struct gpio_chip, so
that also GPIO expanders that block but are still not
using threaded IRQ handlers.
- New drivers for the ARM64 X-Gene SoC GPIO controller.
- The syscon GPIO driver has been improved to handle the
"DSP GPIO" found on the TI Keystone 2 SoC:s.
- ADNP driver switched to use gpiolib irqchip helpers.
- Refactor the DWAPB driver to support being instantiated
from and MFD cell (platform device).
- Incremental feature improvement in the Zynq, MCP23S08,
DWAPB, OMAP, Xilinx and Crystalcove drivers.
- Various minor fixes.

"This is the bulk of GPIO changes for the v3.18 development cycle:
- Increase the default ARCH_NR_GPIO from 256 to 512. This was done
to avoid having a custom <asm/gpio.h> header for the x86
architecture - GPIO is custom and complicated enough as it is
already! We want to move to a radix to store the descriptors going
forward, and finally get rid of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated by
Abdoulaye Berthe. It is not accepted by the system that the
removal of a GPIO chip fails during eg reboot or shutdown, and
therefore the return value has now painfully been refactored away.
For special cases like GPIO expanders on a hot-pluggable bus like
USB, we may later add some gpiochip_try_remove() call, but for the
cases we have now, return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI GPIO
library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle also
threaded, nested interrupts and set up the parent IRQ correctly.
Switch STMPE and TC3589x drivers to use this registration method.
- Add a .irq_not_threaded flag to the struct gpio_chip, so that also
GPIO expanders that block but are still not using threaded IRQ
handlers.
- New drivers for the ARM64 X-Gene SoC GPIO controller.
- The syscon GPIO driver has been improved to handle the "DSP GPIO"
found on the TI Keystone 2 SoC:s.
- ADNP driver switched to use gpiolib irqchip helpers.
- Refactor the DWAPB driver to support being instantiated from and
MFD cell (platform device).
- Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP,
Xilinx and Crystalcove drivers.
- Various minor fixes"

ARM: dts: Disable smc91x on n900 until bootloader dependency is removed
I added smc91x support but turns out we currently do not set the smc91x timings in gpmc.c but rely on the bootloader timings. This produces the following error unless the smc91x GPMC timings are initialized by the bootloader: Unhandled fault: external abort on non-linefetch (0x1008) at 0xd080630e ...
