Subject: board_f: Make init_helpers generic
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=96d4b75c0d7f1bbbbde19e6225b09b1f7e7b60fe;p=u-boot.git

board_f: Make init_helpers generic

This header file is used by two archs. It could be used by all of them
since it allows the cache to be on during relocation. Move it into a
generic file.
