Has SIMH been ported to a low overhead (instant-on)

I ask the question because the startup time of Linux is distracting when
powering on a PiDP-11/70 or similar clone systems based on SIMH.
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.
