0200db650e target-xtensa: add Avnet LX60/LX110/LX200 boards
These boards carry similar hardware: SDRAM (48M for LX110, 64M for LX60,
96M for LX200), 16 Mbyte FLASH, FPGA, 10/100 Mbps Ethernet PHY and 16550
UART. FPGA may be loaded with almost any Tensilica processor. It is also
used to implement Ethernet MAC, e.g. OpenCores 10/100 Mbps Ethernet MAC
and LED/DIP switches access.

ddd1055b07 PPC: booke timers
While working on the emulation of the freescale p2010 (e500v2) I realized that
there's no implementation of booke's timers features. Currently mpc8544 uses
ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for
example booke uses different SPR).

5c145dacac PPC: E500: Add PV spinning code
CPUs that are not the boot CPU need to run in spinning code to check if they
should run off to execute and if so where to jump to. This usually happens
by leaving secondary CPUs looping and checking if some variable in memory
changed.

In an environment like Qemu however we can be more clever. We can just export
the spin table the primary CPU modifies as MMIO region that would event based
wake up the respective secondary CPUs. That saves us quite some cycles while
the secondary CPUs are not up yet.

So this patch adds a PV device that simply exports the spinning table into the
guest and thus allows the primary CPU to wake up secondary ones.

0fc6b5828f Fix build on OpenBSD with BSD userland emu and smartcard NSS enabled
The first issue is the hard coded POSIX Real Time extensions library in the
libcacard/Makefile. From looking at the code it doesn't seem this is necessary
anyway. Robert Relyea seems to think it most likely isn't necessary.

The second issue was the missing exclusion of the BSD userland binary
builds from the addition of this Makefile target for the smartcard NSS
code which breaks the builds if smartcard NSS support is enabled.

093bc2cd88 Hierarchical memory region API
The memory API separates the attributes of a memory region (its size, how
reads or writes are handled, dirty logging, and coalescing) from where it
is mapped and whether it is enabled.  This allows a device to configure
a memory region once, then hand it off to its parent bus to map it according
to the bus configuration.

Hierarchical registration also allows a device to compose a region out of
a number of sub-regions with different properties; for example some may be
RAM while others may be MMIO.

Consequently, the patch removes and build-time checks for kvm and vhost

s390 needs some extra love as it carries redefinitions from kernel
