for target-i386 and target-x86_64:

AFAIK, no one is actually working on these.  EFI is also not terribly useful
without a CSM and I suspect porting SeaBIOS to tiano core is going to be a
big effort.

Several Linux distributions are getting UEFI support ironed out now,
so UEFI can be used without a CSM.  QEMU support for UEFI could
help the Linux distributions to enable UEFI support...

I see a CSM as a pre-requisite for merging a uefi rom. A user can already use a uefi rom by simply using the -bios parameter so there's nothing inhibiting testing. My concern about introducing a new machine type is that it would require duplicate testing and force the selection of uefi up through the management tool stack.

OTH, uefi + a CSM based on SeaBIOS could be used as the default firmware. I don't think it's a reasonable target for 0.12 but I think if someone actively worked on it, it would be possible for future releases.
