arm64: dts: imx943: Correct PCIe outbound address space configuration
Fix the PCIe outbound memory ranges for both pcie1 controllers on i.MX943. The memory window size was incorrectly set to 256MB during initial bring-up, but the hardware supports up to 4GB of outbound address space per controller. Additionally, the ECAM region cannot be mapped as I/O space. Use a memory-mapped region for I/O space instead, and relocate the 1MB I/O region to immediately follow the memory region at offset 0xf0000000 within each window. Update the outbound address space layout per controller as follows: - 3.5GB 64-bit prefetchable memory - 256MB 32-bit non-prefetchable memory - 1MB I/O Fixes: fa6067fd8ea7 ("arm64: dts: imx943: Add pcie1 and pcie1-ep supports") Signed-off-by: Richard Zhu <hongxing.zhu@nxp.com> Signed-off-by: Frank Li <Frank.Li@nxp.com>
