Subject: [PATCH 2/6] drivers/hv: Enable VTL mode for arm64
Date: Fri, 10 May 2024 09:05:01 -0700	[thread overview]
Message-ID: <20240510160602.1311352-3-romank@linux.microsoft.com> (raw)
In-Reply-To: <20240510160602.1311352-1-romank@linux.microsoft.com>

From: Roman Kisel <romank@linux.microsoft.com>

This change removes dependency on ACPI when buidling the hv drivers to
allow Virtual Trust Level boot with DeviceTree.
