commit 409d26d66630c0901403cd46cc34b8007e32922e Author: Julius Werner jwerner@chromium.org Date: Tue Nov 12 14:46:07 2013 -0800
arm: Remove some pointless CFLAGS
This patch removes the -ffixed-r8 CFLAG from the coreboot and libpayload Makefiles. This seems to be a relic from U-Boot, which uses that register to keep it's global data structure pointer. There's no reason for us to throw away a perfectly fine register on this already pretty constrained architecture.
Also removed a config.h inclusion from the Makefile because that should really be done inside the C files.
