I don't think "u-boot/linux boot/embedded systems" vs "UEFI/private
code" is the right distinction. It's "device tree/related" vs
"ACPI/related" as the difference between U-Boot (for example) and EDK II
(for another example) on aarch64 booting a system via EFI is that U-Boot
is likely to be passing in a device tree (setting aside what we can do
on x86 as a digression) and EDK II being likely to pass ACPI/related.
In both cases we can quite easily be talking about all of the data
having been written to persistent flash and automatically passed along.
To riff on a phrase, U-Boot can be quite boring too.
