There is no such thing as a "device tree variant". As long as your
bootloader implements EFI, everything will work correctly, whether
you're using DT, ACPI, or the anything else.
This already works today, without any need to add anything to the
kernel (I have systems using EDK II and u-boot, both implementing EFI,
and I'm able to kexec without any issue). If your bootloader doesn't
support EFI, here's a good opportunity to implement it!
Thanks,
M.
