I think this is a worthwhile effort if someone has the time to fill in the blanks, come up with a PoC, and test it with various versions of BIOS, it would accelerate deprecation of BIOS. BIOS holds us back when making decisions around boot stack, bootloader, firmware upgrade tools, etc. You may

U-Boot for x86 BIOS systems

Hey all, I was chatting with Marcin Juszkiewicz about U-Boot on ARM wrt its "generic UEFI boot" feature where it can execute UEFI applications. We use this capability for Fedora on ARM platforms to go from the utterly barebones and weird initialization processes for various boards to a UEFI-like e
