Hello I am new with coreboot and I am trying to understand base functionalities. Before coreboot I was using SBL and in SBL we could pass data to payload by building HOBs. I searched the coreboot code to see if there is a BuildHOB function but I couldn't find it. Is there a BuildHOB function in coreboot or does it have a different function which could pass data to payload. (I am using EDK2 as payload) Thanks for the answers.
hi Hamit,
with coreboot + edk2 payload, edk2 will parse the necessary info from the coreboot tables in memory (cbmem) and create the HOBs it needs; coreboot does not create them
regards, Matt
