Ryzen Zen2 on-chip BL hangs in error loop

[RobertBuhren]

The Ryzen Zen2 on-chip BL hangs in an error loop. The error probably occurs at 0xffff04cc. Maybe some emulated fuses return invalid values?
When enabling the PSP debug mode via "--psp-dbg-mode", the emulator successfully loads the off-chip bootloader. The off-chip BL however, seems to be stuck after ""POST CODE (X86): PSPSTATUS_MASTER_GOT_BOOT_MODE_AND_SENT_TO_ALL_SLAVES"
