To: u-boot
When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD,
some files fail to build, most of the time because they include
mcr instructions, which only exist for Thumb-2.
This patch introduces a Kconfig option CONFIG_THUMB2 and uses
it to select between Thumb-2 and ARM mode for the aforementioned
files.
Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

This patch has been build-tested and run-tested on ED Mini V2,
above the "edmini: switch to SPL" patch, and found to reduce
U-Boot size by 25% and SPL size by 14%... and to run fine. :)
This patch has also been tested against side effects on the
non-Thumb wireless_space target. The binaries produced with
and without this patch were found to differ only by their
version string.
Changes in v7: None
Changes in v6: None
Changes in v5: None
Changes in v4: None
Changes in v3:
- added arch/arm/lib/mem{set,cpy}.S to the list of modules
which should always be built in ARM state.
- Selected HAS_THUMB2 for CPU_V7M.
- Fixed invalidate_l2_cache() when building for Thumb-1.
Changes in v2:
- fixed a typo in the commit message
- added file arch/arm/thumb1/include/asm/proc-armv/system.h,
which overrides arch/arm/include/asm/proc-armv/system.h
when building for Thumb-1 and provides non-functional but
Thumb-compilable IRQ and FIQ related macros and functions.
