Here some concrete examples. The major bootloaders on ARM today are:
        * UEFI
        * U-boot
        * GRUB

I will leave UEFI aside as people will usually chainload to GRUB and
then boot whatever they want.

In both GRUB and U-boot a user will be able to modify the command line
from the bootloader shell.

Thanks. So I think the takeaway is that ARM doesn't strictly need
the Dom0 part of the handling, but then again if this was common
code it also shouldn't hurt.

Correct. As long as the he expected behavior (e.g how they options are combined) is fully documented.

Note that I was not able to find any documentation about this in xen-commandline.markdown.

Cheers,
