From: Grant Likely Date: Wed, 10 Oct 2007 18:48:18 +0000 (+1000) Subject: [POWERPC] Only call ppc_md.setup_arch() if it is provided X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=38db7e740ade7f07f6315e3a3b1172d7e456b793;p=openwrt%2Fstaging%2Fblogic.git [POWERPC] Only call ppc_md.setup_arch() if it is provided This allows platforms which don't have anything to do at setup_arch time (like a bunch of the 4xx platforms) to eliminate an empty setup_arch hook.
