http://www.coreboot.org/pipermail/coreboot/2007-September/024665.html It's about time we follow this advice. Also move some manually set __PRE_RAM__ defines (ap_romstage.c) to the Makefile and drop unused CPP define Signed-off-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Acked-by: Patrick Georgi <patrick@georgi-clan.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6482 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
