[PATCH 2/2] arm64: dts: qcom: agatti: Address Gunyah memory alignment needs

From: Sumit Garg
Date: Mon Dec 29 2025 - 02:13:55 EST


From: Sumit Garg <sumit.garg@xxxxxxxxxxxxxxxx>

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.
