Forgive me if this sounds weird, but I was under the impression that
most people who want to reflash their BIOS on x86 (most prominent
physmap usecase on x86) are using a pure userspace solution with
flashrom <> nowadays.

flashrom has the advantage of not needing a kernel recompile if you want
support for new chips/chipsets. flashrom doesn't use MTD and accesses
/dev/mem instead. AFAIK flashrom supports BIOS/EFI/... flashing on all
x86 chipsets which are supported by MTD, and on a few other x86 chipsets
(and network/storage/graphics cards) which are not supported by MTD.
