Haven't seen anything, but Linux can be made to boot much faster, e.g.
if you have hardware which supports Coreboot firmware/BIOS, Linux can
also be loaded from flash along with this, as its payload. So maybe this
and a very minimal filesystem generated with something like
OpenEmbedded, could be one approach.

Also wondered if SimH could be ported to a UEFI application. The
environment seems to provide some O/S like features, but no idea how
much would be missing or significantly different.
