It seem way worse with newer "FSP" blobs...
On qemu, coreboot is not necessary: some coreboot payloads (like
seabios) are capable of beeing the full bootstrap firware(because
qemu is really simple: most of the complex hardware already works).
Then I really wonder what's left for coreboot in the systems that uses
the FSP blob.
If I understood correctly, coreboot would run as hooks, and do some
mostly standard stuff that a payload (or coreboot) can do.
Then at the end coreboot would run a payload.
