-gerrit commit 3275900df69bc56d723f17abc5f88250ac9a4b31 Author: David Hendricks <[email protected]> Date: Thu Dec 27 13:30:55 2012 -0800 update CFLAGS for armv7 This updates $CFLAGS used for armv7. Most of them were just added to be consistent with what u-boot does. The important ones here are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions). I removed the hard float support because it got errors and coreboot should never use floats anyway. We're still having trouble with enums but I want to see how far it gets with this patch.
