From: Michael Neuling Date: Mon, 25 Jun 2012 13:33:16 +0000 (+0000) Subject: powerpc: Change mtcrf to use real register names X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=86e32fdce7c6582a52b9468106714779d871c773;p=openwrt%2Fstaging%2Fblogic.git powerpc: Change mtcrf to use real register names mtocrf define is just a wrapper around the real instructions so we can just use real register names here (ie. lower case). Also remove braces in macro so this is possible.
