Re: You still missed the basic.

Going with UEFI in an embedded system is really overcomplicated. Some industrial boot loaders (u-boot, that may be used as a coreboot payload for Intel for those crazy enough to uses their chips in a embedded context) do the job very nicely without unneeded pain. And avoiding to build dependencies in code between the boot loader and the OS. Aka the UEFI runtime services, that replace the old BIOS "interrupts" that used to provide such services & were abused very early by boot viruses... leading their modern counterpart UEFI to implement secure boot. Complexity over complexity to fix a very bad dependency that is as much as possible avoided elsewhere but Microsoft always relied on.
That's what I call "basics".
