[U-Boot] [PATCH 1/8] POST/arm: adaptations needed for POST on ARM to work

[Valentin Longchamp]

For post to run on ARM, 3 things are needed:
- post_log_word to be defined in gd
- a post.h include in arch/arm/lib/board.c
- most ARM boards will set POST_WORD in RAM, so we need gd->ram, and
  thus DECLARE_GLOBAL_DATA_PTR is needed in post.h
