Thanks for your patch!

Might be easier to read and maintain by splitting in "hard" and "useful"
dependencies:
depends on OF
depends on ARCH_SOCFPGA || NIOS2 || COMPILE_TEST

This means it is only useful on DT-based Exynos platforms, but compiles
everywhere?
Do you still have support for non-DT Exynos platforms?
ARCH_EXYNOS depends on ARCH_MULTI_V7?
(and its help text mentions Exynos 4/5 only, no 3?)

Perhaps
depends on ARCH_TEGRA || COMPILE_TEST
depends on ARC || ARM || ARM64 || M68K || RISCV || SUPERH || SPARC
# needs <foo>
to remember which <foo> feature is needed?
