OTOH, it could simply be an ELF loaded by FILO. That allows upgrades of
flashrom as needed, and if FILO can load flash images from any media, it
should be able to do the same with executable code.

Now that is indeed a compelling reason to have FILO support flashing.
Then again, if flashrom-in-FILO doesn't check a cryptographic signature
of the new flash image, the flash protection effect is rather limited.

Anyway, I can do it if you let me do it.
