Heiko Schocher - April 1, 2011, 7:16 a.m.
From: Holger Brunck <holger.brunck@keymile.com>

This patch reworks all headerfiles for keymile boards. Furthermore
the environment variables are refactored.

Changes:
  - introduce km-powerpc.h file and extract ppc specific parts to it
  - move ARM specific options and vaiables to km_arm.h
  - sort the environment variables to logical groups
  - enhance the description of the environment variables
  - remove KM specific HW key and board id from kernel command line

Changes for v2:
  - new patch in v2, first patch in v1 was split up
  - fix checkpatch.pl errors and warnings
Changes for v3:
  - rebased only
