Subject: [PATCH] SUPPORT.md: clarify support of booting 32-bit Xen on ARMv8
Date: Thu, 29 Feb 2024 13:13:52 +0100	[thread overview]
Message-ID: <20240229121352.11264-1-michal.orzel@amd.com> (raw)

Since commit bd1001db0af1 ("xen/arm: arm32: Allow Xen to boot on
unidentified CPUs"), it's been possible to boot 32-bit Xen on ARMv8A CPUs
in AArch32 state (assuming HW supports EL2 execution in AArch32). Clarify
the support statement and mark it as Tech Preview, as this use case is
uncommon and hasn't really been tested/hardened.
