From: Andreas Bießmann Date: Mon, 26 May 2014 20:55:18 +0000 (+0200) Subject: macb: make checkpatch clean X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ceef983bf9b687926b274ad0eee8aae5a1812c92;p=u-boot.git macb: make checkpatch clean This also renames the CONFIG_SYS_MACB_xx defines. They are used just local and therefore don't need the CONFIG_SYS_ prefix.
