I have been in trouble for a while to debug some nasty problem
where neighter a debugger nor printf() function is available.
I found the lowlevel debug feature in ARM Linux can be used as is
in U-Boot too.
I tested this series on our SoCs (32bit ARM, specificly Coretex-A9).
Because I was not sure about aarch64, I have this feature
depend on ! ARM64.
1/6 and 2/6 refactor a bit and move CONFIG_ARM64 to Kconfig.
3/6 imports some source files from Linux 3.16 and
5/6 adds the Kconfig menu.

vexpress64: kconfig: consolidate CONFIG_TARGET_VEXPRESS_AEMV8A_SEMI
kconfig: armv8: move CONFIG_ARM64 to Kconfig
arm: debug: import debug files from Linux 3.16
arm: debug: replace license blocks with SPDX
arm: debug: add Kconfig entries for lowlevel debug
arm: debug: adjust for U-Boot

Tested on Trats2(Exynos4412) - works fine.
