Hi all,

I've been working with Ben Dooks to get a big-endian kernel working on
my Exynos 4412 board.  Primarily this series consists of:

  - Replacing the __raw_{read,write}l accessors, which aren't
    endian-clean, with their respective {read,write}l_relaxed versions
    across various drivers.

  - Adding endian-aware {set,clear}_bit functions to the Exynos serial
    driver as the __{set,clear}_bit() functions aren't endian-clean.

  - Make the low-level Exynos debug printing macros endian-clean.

There may well be other things that are broken under BE that we've not
tested but this series should be enough to allow a board to boot
user-space to a login prompt.

Comments/feedback welcome!

Thanks,
Matt
