Subject: POST: allow redefinition of post_word_load/store
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3e161ced8fd3276aa77e4276e9237ae972b21f33;p=u-boot.git

POST: allow redefinition of post_word_load/store

The predefinde post_word_load/store functions do not fit all boards,
so we introduce a way to define post_word_load/store as externs in
post.h that then can be defined in board specific files. This is done
with the CONFIG_POST_EXTERNAL_WORD_FUNCS #define
