Yeah, it needs fixing but we absolutely want to build the roms as part
of the normal build process.

I disagree. For the most part I'd expect roms to be better maintained as a side project.

For things like gpxe where there's a well defined boundary between QEMU and the rom, yes, that makes sense.

For something like the PC BIOS, it's proven to be very difficult to maintain it out of tree. It's difficult for people to develop patches for it, difficult for people to test those patches, and then difficult for the maintainers to pull in those patches.

Making it part of the tree and a standard part of the build system will tremendously simplify that.

I think the chances of the user having appropriate toolchains readily available (without significant additional per-rom configury) are extremely slim.

Actually, for x86, all of our ROMs will just use GCC so when building x86 on x86, it's very likely the right tool chain is available.
