Hi At present, I don't see any specific hardware requirement for EBBR except
ARMv8 CPU. Current document covers it very well.
You have to have block storage. Perhaps UEFI implies that. Boards like the CHIP only have raw NAND and a USB connector by default. So is USB MS enough?
Yes but such need is not must to have EBBR running.
I think being explicit with h/w requirements implied by UEFI would be a good thing. If I'm designing a board, I don't want to have to sort thru UEFI specs to distill down a bullet list of h/w reqs.
I like to cover here, all on/off chip components could be IP/peripherals needed for EBBR. Like if USB is present, minimum version of xchi or echi needs to be supported by hardware.

IMO, we can deferred this ticket. Thoughts ?
