Which isn’t to say we shouldn’t do it; but it might be nice to also have an
intermediate solution that works right now, even if it’s not optimal.
I propose the following behaviour by updste-grub:
1. Look for an ELF note, TBD. If it's found, make XSM boot entries.
(For now, skip this step, since the ELF note is not defined.)
I am afraid the ELF note is a very x86 thing. On Arm, we don't have such
thing for the kernel/xen (actually the final binary is not even an ELF).
2. Look for a .config alongside the Xen binary. Look for
^CONFIG_XSM_FLASK=y
If the file is is not found, or no line matches, make no XSM
boot entries.
... this would probably be the best solution for Arm.
