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. -- Without deviation from the norm, progress is not possible. _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
