Subject: [PATCH 7_9] Replace ace_readw_ace_writeb functions with macros
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f4852ebe6ca946a509667eb68be42026f837be76;p=u-boot.git

[PATCH 7_9] Replace ace_readw_ace_writeb functions with macros

Register read/write does not need to be wrapped in a full function.  The
patch replaces them with macros.
