PS1, Line 9: When USE_PSPSECUREOS isn't selected, we get stuck in FSP-S.
> Is that by design, or a bug in FSP-S?

in stoneyridge with psp generation 1 that part of amdfw was optional; it's not optional for the psp generation 2 that is used on picasso/cezanne, so without that it'll be operating out of spec; fsp-s is just the place where we probably have an assert for the psp being unhappy about that. so i'm pretty sure that it's not a bug in fsp-s; i am however a bit surprised that it even gets so far without that part of the psp firmware. i don't have much visibility into what the psp wants and does exactly though
