description:
Reorganize Exynos code step 1 of N
create config files that use evbarm/exynos rather than evbarm/odroid for
the machdep portion.
point ODROID-XU4 at those files
add evbarm/exynos/exyos_{start.S, machdep.c} and platform.h that are exynos
5422 specific. -- We'll edit in other exynos platforms once this one
fully works.
This boots the Odroid XU4 to the same point as using evbarm/odroid does, but
with some differences in gpio handling. Everything else should be semantically
equivalent.
