Subject: [PATCH v4 2/2] arch: arm64: boot: dts: qcom: add IMEM and PIL regions for glymur
Date: Fri, 27 Mar 2026 03:24:36 -0700	[thread overview]
Message-ID: <20260327-glymur-imem-v4-2-8fe0f20ad9fd@oss.qualcomm.com> (raw)
In-Reply-To: <20260327-glymur-imem-v4-0-8fe0f20ad9fd@oss.qualcomm.com>

Add an IMEM on glymur which falls back to mmio-sram and define the
PIL relocation info region as its child, for post mortem tools to
locate the loaded remoteprocs.
