[PATCH v2 0/2] arm64: dts: qcom: shikra: Add EL2 overlay for EVK variants
From: Komal Bajaj
Date: Wed Sep 30 2026 - 08:00:41 EST
All existing Shikra EVK board variants boot Linux under a hypervisor,
which means Linux typically runs at EL1. For EL2 boot without the
hypervisor, remote processor firmware IOMMU streams must be described in
the DeviceTree consumed by Linux.
Add a Shikra EL2-specific DT overlay and wire it up in the Makefile to
produce -el2.dtb artifacts for the Shikra EVK variants alongside the
regular dtbs.
This series also relaxes the Qualcomm PAS remoteproc `iommus` item limit,
needed for Shikra EL2 remoteproc SMMU mappings.
