FSBL authentication by BootROM

Dear community

Despite extensive research in UG585 and UG850 I could not answer the following question clearly:
What does the BootROM use to authenticate the FSBL? Does it only get access to the PPK hash, or does it also use a vendor specific endorsement key embedded somewhere in the FSBL?

Friendly greetings

Can section 32.2.5 in UG585(v1.12.2) answer your questions?

Is this the only measure performed to authenticate a FSBL?
