The LinuxLoader is a legacy thing which needs to go away.
Proper UEFI support in the kernel is one way of making that possible.

Don't really understand yor comments about the arm kernel UEFI support,
but there seems to be some misunderstanding here, so I don't think going
over your email and tickbox-refuting them one by one will be of much
use to anyone.

I will be posting an updated set of the arm patches today, to go with
the updated UEFI stub patches submitted by Roy last night. I will be
happy to discuss the topics mentioned as part of this message as part
of the review of those, if you still consider them an issue.

But let's be clear - my intent is to get UEFI first-class citizen
status in the arm kernel.
