[PATCH v2 2/3] arm64: dts: imx94: Avoid 32-bit PCIe window System RAM overlap
From: hongxing . zhu
Date: Fri Aug 21 2026 - 01:40:24 EST
From: Richard Zhu <hongxing.zhu@xxxxxxx>
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: ffccbd6804e88 ("arm64: dts: imx94: Correct PCIe outbound address space configuration")
