This patch series fixes PCIe non-prefetchable memory window overlap with system DRAM on i.MX9 series SoCs (imx95, imx94, and imx943). The current CPU address 0xe0000000 conflicts with DRAM regions. Sashiko reports the similar potential issue in below review: https://lore.kernel.org/imx/[email protected]/ The fix relocates the CPU address to 0x10000000, a reserved and safe range. The PCI bus address and window size remain unchanged.
