This patchset adds support for building a 64bit PowerPC little
endian kernel.
binutils and gcc support (powerpcle/powerpc64le) is already
upstream. For gcc you can use gcc tip, or for the less adventurous
the gcc 4.8 branch works too.
QEMU patches to boot a little endian kernel will be posted

We want ppc64 to be able to select between optimised assembly
checksum routines in big endian, and the generic lib/checksum.c
routines in little endian.
The lpfc driver is forcing CONFIG_GENERIC_CSUM on which means
we are unable to make the choice of when to enable and disable
it in the arch
We need to fix some endian issues in our checksum code. For now
just enable the generic checksum routines for little endian builds.

This patch allows the kbuild system to successfully compile a kernel for
the little endian PowerPC64 architecture.
To build such a kernel a supported platform must be used and
CONFIG_CPU_LITTLE_ENDIAN must be set. If cross compiling, CROSS_COMPILE
must point
POWER7 takes alignment exceptions on some unaligned addresses, so
disable HAVE_EFFICIENT_UNALIGNED_ACCESS. This fixes an early boot
issue in the printk code.

This is the pseries_defconfig with CONFIG_CPU_LITTLE_ENDIAN enabled
and CONFIG_VIRTUALIZATION disabled (required until we fix some
endian issues in KVM).

Perhaps it is a BIOS option ROM like you suggested earlier. The

- fixes several drivers that are used in the MPC512x platform (UART,
SPI, ethernet, PCI, USB, CAN, NAND flash, video capture) in how they
handle clocks (appropriately acquire and setup them, hold references
during use, release clocks after use)
- introduces support for the common
cleanup the MPC512x SoC's SPI master's use of the clock API
- get, prepare, and enable the MCLK during probe; disable, unprepare and
put the MCLK upon remove; hold a reference to the clock over the
period of use
- fetch MCLK rate (reference) once during probe and slightly reword BCLK
cleanup the clock API use of the UART driver which is shared among the
MPC512x and the MPC5200 platforms
- get, prepare, and enable the MCLK during port allocation; disable,
unprepare and put the MCLK upon port release; hold a reference to the
clock over the period of use; check for and
use devm_clk_get() for automatic put after device close, check for and
propagate errors when enabling clocks, need to prepare clocks before
they can get enabled, adjust error code paths to correctly balance
get/put and prepare/unprepare and enable/disable calls
