I'm more worried about the CONFIG_OPTIONROMS_DEPLOYED patches for

That's a good point. Need to think about how to best handle that.
SeaBIOS supports up to two static option roms so maybe what we need to
do is make use of that mechanism for things like linuxboot/extboot.
Keep loading custom roms (e.g. from -option-rom) with rom_add_file starting at
0xc8000.
Modify SeaBIOS to scan the memory range for pre-deployed option roms before
deploying
PCI roms. SeaBIOS will find the last pre-deployed rom and have a starting
address for
deploying PCI roms. This will keep ISA option roms working.
