According to Platform Initialization (PI) Specification [1] and
discussion on edk2 mailing list [2],
StandaloneMm shouldn't create Hob but it should be passed from TF-A.
IOW, TF-A should pass boot information via HOB list to initialise
StandaloneMm properly.
And this HOB lists could be delivered via
- SPM_MM: Transfer List according to the firmware handoff spec[3]
- FF-A v1.1 >= : FF-A boot protocol.
This patch introduces a TF-A HOB creation library and
some of definitions which StandaloneMm requires to boot.
