As far as I know they’re all configured to, and we should be pushing to
make sure they continue to, especially as it requires basically no
effort from them other than enabling a config option. Other operating
systems, both Linux and non-Linux, use, or even require, UEFI support
for booting. If all the major distros only provide UEFI-using media
then the path of least resistance for vendors will be to use that
rather than other pre-U-Boot UEFI support Linux-specific boot methods.
Let’s not repeat the arm and arm64 histories a third time.
