[PATCH v2 1/3] arm64: dts: imx95: Avoid 32-bit PCIe window System RAM overlap
From: <hidden>
Date: 2026-08-21 05:39:43
Also in:
imx, linux-devicetree, lkml
Subsystem:
arm/freescale imx / mxc / layerscape arm architecture, the rest · Maintainers:

From: Richard Zhu <hongxing.zhu@nxp.com>
Move the PCIe non-prefetchable memory PCI bus address from 0xe0000000
to 0x10000000 to avoid overlap with DRAM. The 0x10000000 range is
reserved and safe to use.
Fixes: dbecf38e60d4e ("arm64: dts: imx95: Correct PCIe outbound address space configuration")
