Hi Heinrich,

What if I just want a simple embedded boot stack where I don't
want any secure world and just want to be able to boot a COTS linux
distribution via EFI?

Assuming, that there might be a simple dedicated EEPROM to store the
variables which is not exposed to linux, is that something which would
be rejected by u-boot mainline now?
