Yes, that would also work if we find a compelling reason to keep it that
way. You can actually keep it private to fs/minix/Kconfig by writing it
as
config MINIX_FS_NATIVE_ENDIAN
def_bool y
depends on H8300 || M32R || MICROBLAZE || MIPS || S390 || SUPERH || SPARC || XTENSA
We normally use select for arch specific options, but in this case I think
I would prefer the single option since we know we don't want new architectures
to do it too.
