From 92ccf83b8d58f9dca5752a824f0e81ac54665889 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Mon, 20 Jul 2026 22:12:11 +0800 Subject: [PATCH] arm64: dts: imx8ulp: Correct SRAM node address and size to cover full SSRAM P2 The SSRAM P2 partition starts at 0x22010000 with a size of 64 KB. The previous node only mapped the last 4 KB (0x2201f000, 0x1000) which was used for the SCMI shared memory buffer. Update the base address and size to cover the full P2 region so it can also serve as a general purpose SRAM pool.
