I don't think one should exclude the other, I think it would make
great sense to combine them. So have coreboot on QEMU read some
hardware description from QEMU and use that either as input to a
table generator, or even have the read data be the tables themselves.
It might or might not be easier and/or make more sense to generate
tables in coreboot rather than in QEMU - that's unclear so far.

Is there something inherent to the AML generator code in coreboot
which makes it suck for the purpose of also generating a DSDT?
