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 Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Kim Phillips <kim.phillips@freescale.com> cc: Kim Phillips <kim.phillips@freescale.com> cc: Wolfgang Denk <wd@denx.de> cc: Valentin Longchamp <valentin.longchamp@keymile.com>master
