Subject: [PATCH] xen/arm: Remove EXPERT dependancy
Date: Wed, 21 Oct 2020 18:43:10 -0700	[thread overview]
Message-ID: <20201022014310.GA70872@mattapan.m5p.com> (raw)

Linux requires UEFI support to be enabled on ARM64 devices.  While many
ARM64 devices lack ACPI, the writing seems to be on the wall of UEFI/ACPI
potentially taking over.  Some common devices may need ACPI table
support.

Presently I think it is worth removing the dependancy on CONFIG_EXPERT.
I am rather tempted to add defaulting enabled, but I'm not yet confident
of going that far yet.

I hope a popular ARM device capable of running Xen will soon be running
Xen on ACPI/UEFI, but it isn't quite there yet.  As such I would like to
have "default y", but I don't think that is likely to be accepted yet.
