[U-Boot] [PATCH v3 0/8] POST: support for km_arm and mem_regions test definition

[Valentin Longchamp]

This series adds support for POST on the km_arm boards. These boards use a jumper
to run some self-tests at the board power-up. There are some adaptations for POST
to run on the ARM architecture.

This series defines a new mem_regions POST test. This test also takes place before
relocation, but it only tests some regions of the RAM so that it is quicker.

Changes for v2:
 - added CONFIG_POST_EXTERNAL_WORD_FUNCS to allow to redefine post_word_load/store
   in the board support file when the proposed functions are not suitable.

Changes for v3:
 - moved COFNIG_POST_EXTERNAL_WORD_FUNCS to an individual patch
 - moved memory test configuration for km_arm from post to board code

Valentin Longchamp (8):
  POST/arm: adaptations needed for POST on ARM to work
  POST: allow redefinition of post_word_load/store
  POST: add post_log_res field for post results in global data
  POST: make env test flags fetching optional
  POST: drivers/memory.c coding style cleanup
  POST: add new memory regions test
  km_arm: change CONFIG_SYS_TEXT_BASE to end of RAM
  km_arm: enable POST for these boards
