Subject: [PATCH v2 3/9] arm64: dts: imx8ulp: Correct SRAM node address and size to cover full SSRAM P2
Date: Mon, 20 Jul 2026 22:12:11 +0800 [thread overview]
Message-ID: <20260720-imx8ulp-dts-v2-3-d05c67676f53@nxp.com> (raw)
In-Reply-To: <20260720-imx8ulp-dts-v2-0-d05c67676f53@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
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.
