2013-01-04update CFLAGS for armv7David Hendricks
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.

2013-01-03armv7: pass bootblock offset from Kconfig into cbfstoolDavid Hendricks
This replaces a somewhat useless calculation used earlier (which always evaluated to 0) with an offset to specify the location of the Coreboot bootblock.

2013-01-03armv7: create init.S for early ARMv7 initDavid Hendricks
The old start.S file did a lot of work and had AP-specific #ifndef's. The new init.S will eventually contain only bare minimum generic ARM code for use by the bootblock. Processor-specific stuff and things that take place later in the boot process should go elsewhere.
