how to enumerate all ROMs on a system?

Hi,

Dumb question of the day: :-)

Besides the main system ROM image, I'm wondering how to enumerate what
other Option/Expansion ROMs there might be on the system and it's
peripherals, both legacy BIOS as well as new UEFI, all architectures,
and busses (ISA, PCIe, etc.) not just the subset that're loaded.

I don't know much about USB and how their firmware works. I've been told
they don't have Option ROMs, is there some USB place to look for
non-OpROM-based firmware?

Is there a way to do this, with chipsec_util? If not chipsec_util, does
anyone know of any other tool that could help? If no tool, could anyone
help point to the right specs/sections so I can read up on how to do it?

Thanks,
Lee
