Subject: [PATCH 2/2] arm64: dts: qcom: agatti: Address Gunyah memory alignment needs
Date: Mon, 29 Dec 2025 12:42:58 +0530	[thread overview]
Message-ID: <20251229071258.456254-2-sumit.garg@kernel.org> (raw)
In-Reply-To: <20251229071258.456254-1-sumit.garg@kernel.org>

From: Sumit Garg <sumit.garg@oss.qualcomm.com>

Gunyah hypervisor requires it's memory start address to be 2MB aligned.
So the address map for Agatti is updated to incorporate that requirement.
This should be a backwards compatible DT change which should work with
legacy QHEE based firmware stack too.
