Subject: [PATCH 2/2] arm64: dts: qcom: agatti: Address Gunyah memory alignment needs
Date: Mon, 29 Dec 2025 12:37:12 +0530 [thread overview]
Message-ID: <20251229070712.456138-2-sumit.garg@oss.qualcomm.com> (raw)
In-Reply-To: <20251229070712.456138-1-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.
