FSP integration

[Zvi Vered]

Hello,

I'm using an FSP file for coreboot porting.
According to Intel's "atom-e3800-fsp-integration-guide":
FspInit is calling "Bus and Devices Init"
NotifyPhase is calling "Boot Device Init"

How can I know what initialization is required in each phase ?

FSP has documented return values.
I assume FSP is run by coreboot.
Where can I inspect this return value ?

Thank you,
Zvika
