From 10c90d31264b5698320a1ac2666823532d110258 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Thu, 27 Dec 2012 13:30:55 -0800 Subject: 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. Also, put the flags in a form that makes diffs easier to read. It's almost impossible otherwise. Finally, move some flags to the architecture Makefile, and rely on the fact that some are set for all architectures.
