![]() 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.
