Subject: [PATCH 7_9] Replace ace_readw_ace_writeb functions with macros
X-Git-Tag: v1.3.0-rc1~164^2~2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f4852ebe6ca946a509667eb68be42026f837be76;p=karo-tx-uboot.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.
