Locations of SEEPROM and BMC SPI Flash

I can find this reference on IBM's site, https://developer.ibm.com/technologies/linux/articles/protect-system-firmware-openpower

The SBE has several stages, with the first part stored in processor one-time programmable read-only memory (OTPROM) and another part stored in the SEEPROM module located on the POWER processor module.

which suggests that SEEPROM is actually a tiny chip outside the POWER9?/POWER8? die, but I am not positive.

Also, this wiki page mentions "BMC SPI Flash", but I am unsure if this is a separate physical flash chip from PNOR?
