433c858a61 powerpc/85xx: mpc85xx ADS: remove pci exclude
This code was reworked in commit,

905e75c46d

This change removed the fsl_add_bridge() which originally was above
the addition of the pci_exclude_device function. I think the assumption was that
the pci_exclude_device would prevent changes to the bridge PCI config after
it's been added. It seems it wasn't fully tested on MPC85xx ADS because
if you move the fsl_add_bridge() the pci_exclude_device is set in the machine
description then you can never update the PCI Config since the exclude
prevents it. This disrupts things like DMA.

This issue was extensively debugged by David Beazley.

720d7aebcd powerpc/85xx: Add PCIe controller support for bsc9132qds
1. Use machine_arch_initcall to hook mpc85xx_common_publish_devices
This can ensure before pcibios_init() is called, pci controllers have
been probed and added to the hose_list.
2. Add a workaround for errata A-005434
For the BSC9132, PEX_PEXIWARn[TRGT] for all windows defaults to 0xF,
which is mapped to CCSRBAR. However, for other products, 0xF is
mapped to the local memory. Therefore, for the BSC9132, any default
PCI Express access to the local memory (DDR) will now access the
CCSRBAR. This patch changes the mapping of targets of inbound windows
PEX_PEXIWARn[TRGT] to the Local address space – 0x0 (from 0xF).

1112450a18 powerpc/85xx: Don't use generic timebase sync on 64-bit
85xx currently uses the generic timebase sync mechanism when
CONFIG_KEXEC is enabled, because 32-bit 85xx kexec support does a hard
reset of each core.  64-bit 85xx kexec does not do this, so we neither
need nor want this (nor is the generic timebase sync code built on
ppc64).

FWIW, I don't like the fact that the hard reset is done on 32-bit
kexec, and I especially don't like the timebase sync being triggered
only on the presence of CONFIG_KEXEC rather than actually booting in
that environment, but that's beyond the scope of this patch...

9f640bf532 powerpc/fsl-corenet: Disable coreint if kexec is enabled
Problems have been observed in coreint (EPR) mode if interrupts are
left pending (due to the lack of device quiescence with kdump) after
having tried to deliver to a CPU but unable to deliver due to MSR[EE]
-- interrupts no longer get reliably delivered in the new kernel.  I
tried various ways of fixing it up inside the crash kernel itself, and
none worked (including resetting the entire mpic).  Masking all
interrupts and issuing EOIs in the crashing kernel did help a lot of
the time, but the behavior was not consistent.

Thus, stick to standard IACK mode when kdump is a possibility.

01c593d749 powerpc/fsl-booke-64: Allow booting from the secondary thread
This allows SMP kernels to work as kdump crash kernels.  While crash
kernels don't really need to be SMP, this prevents things from breaking
if a user does it anyway (which is not something you want to only find
out once the main kernel has crashed in the field, especially if
whether it works or not depends on which cpu crashed).

379caf6063 powerpc: mpc85xx: flush the l1 cache before cpu down in kexec
We observe a "Zero PT_NOTE entries found" warning when vmcore_init()
is running on the dump-capture kernel. Actually the PT_NOTE segments
is not empty, but the entries generated by crash_save_cpu() are not
flushed to the memory before we reset these cores. So we should flush
the l1 cache as what we do in cpu hotplug. With this change, we can
also kill the mpc85xx_smp_flush_dcache_kexec() since that becomes
unnecessary.

Please note: this only fix the issue on e500 core, we still need to
implement the function to flush the l2 cache for the e500mc core.
Fortunately we already had proposing patch for this support [1].
Hope we can fix this issue for e500mc after that merged.

e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

9178ba294b powerpc: Convert power off logic to pm_power_off
The generic Linux framework to power off the machine is a function pointer
called pm_power_off. The trick about this pointer is that device drivers can
potentially implement it rather than board files.

Today on powerpc we set pm_power_off to invoke our generic full machine power
off logic which then calls ppc_md.power_off to invoke machine specific power
off.

However, when we want to add a power off GPIO via the "gpio-poweroff" driver,
this card house falls apart. That driver only registers itself if pm_power_off
is NULL to ensure it doesn't override board specific logic. However, since we
always set pm_power_off to the generic power off logic (which will just not
power off the machine if no ppc_md.power_off call is implemented), we can't
implement power off via the generic GPIO power off driver.

To fix this up, let's get rid of the ppc_md.power_off logic and just always use
pm_power_off as was intended. Then individual drivers such as the GPIO power off
driver can implement power off logic via that function pointer.

With this patch set applied and a few patches on top of QEMU that implement a
power off GPIO on the virt e500 machine, I can successfully turn off my virtual
machine after halt.

e16c876553 powerpc/e6500: Add support for hardware threads
The general idea is that each core will release all of its
threads into the secondary thread startup code, which will
eventually wait in the secondary core holding area, for the
appropriate bit in the PACA to be set. The kick_cpu function
pointer will set that bit in the PACA, and thus "release"
the core/thread to boot. We also need to do a few things that
U-Boot normally does for CPUs (like enable branch prediction).

497c8b6096 powerpc/mpc85xx: add support for Keymile's kmcoge4 board
This patch introduces the support for Keymile's kmcoge4 board which is
the internal reference design for boards based on Freescale's
P2040/P2041 SoCs. This internal reference design is named kmp204x.

The peripherals used on this board are:
- SPI NOR Flash as bootloader medium
- NAND Flash with a ubi partition
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
  CPLD
- 2 I2C busses
- last but not least, the mandatory serial port

The patch also adds a defconfig file for this reference design that is
necessary because of the lowmem option that must be set higher due to
the number of PCIe devices with big ioremapped mem ranges on the boad.

2751b628c9 powerpc: Fix SMP issues with ppc64le ABIv2
There is no need to put a function descriptor in
__secondary_hold_spinloop. Use ppc_function_entry to get the
instruction address and put it in __secondary_hold_spinloop instead.

Also fix an issue where we assumed cur_cpu_spec held a function
descriptor.

48b16180d0 fsl/pci: The new pci suspend/resume implementation
If we do nothing in suspend/resume, some platform PCIe ip-block
can't guarantee the link back to L0 state from sleep, then, when
we read the EP device will hang. Only we send pme turnoff message
in pci controller suspend, and send pme exit message in resume, the
link state will be normal.

When we send pme turnoff message in pci controller suspend, the
links will into l2/l3 ready, then, host cannot communicate with
ep device, but pci-driver will call back EP device to save them
state. So we need to change platform_driver->suspend/resume to
syscore->suspend/resume.

So the new suspend/resume implementation, send pme turnoff message
in suspend, and send pme exit message in resume. And add a PME handler,
to response PME & message interrupt.

Change platform_driver->suspend/resume to syscore->suspend/resume.
pci-driver will call back EP device, to save EP state in
pci_pm_suspend_noirq, so we need to keep the link, until
pci_pm_suspend_noirq finish.
