[PATCH v2 3/9] arm64: dts: imx8ulp: Correct SRAM node address and size to cover full SSRAM P2

From: Peng Fan (OSS)

Date: Mon Jul 20 2026 - 10:47:46 EST


From: Peng Fan <peng.fan@xxxxxxx>

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.
