[RFC PATCH 0/4] Big Endian support for ARM64 kernel

[ankit.jindal@linaro.org (Ankit Jindal)]

This patchset adds support for using Big Endian mode of AArch64 CPUs

All patches have been tested on APM X-Gene Storm SOC.

The Big Endian toolchain used for development can be found at:
http://cbuild.validation.linaro.org/snapshots/big_endian

We have tested both 32bit BE and 64bit BE root filesystems with these
patches.

The 64bit BE root filesystem was build manually using busybox-1.21.1 and
above mentioned toolchain.

The 32bit BE root filesystem was readily available from Linaro releases
located at: http://snapshots.linaro.org/openembedded/images

Ankit Jindal (4):
  ARM64: Add Kconfig option to enable Big Endian kernel
  ARM64: Include appropriate byteorder for Big Endian
  ARM64: Big Endian fixes for kernel booting
  ARM64: Support for 32-bit big endian userspace
