Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson, Karthik Ramasubramanian, Felix Held,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/59867

to look at the new patch set (#3).

Change subject: soc/amd/cezanne: Separate signed amdfw
......................................................................

soc/amd/cezanne: Separate signed amdfw

Put signed amd firmwares into SIGNED_AMDFW_[AB] region which is outside
FW_MAIN_[AB]. Vboot only verifies FW_MAIN_[AB] so these regions will not
be verified by vboot; instead the PSP will verify them.

As a result we have less to load and verify from SPI rom which means
faster boot time.

BUG=b:206909680
TEST=build guybrush with modified fmap and Kconfig
