Things seemed to change rapidly that in Nov 2014 with the following QEMU commits: commit e6b4e5f4795b ("PPC: e500: Move CCSR and MMIO space to upper end of address space") and commit cb3778a0455a ("PPC: e500 pci host: Add support for ATMUs") the PCI memory and IO physical address were moved to beyond 4 GiB, but PCI bus address remained below 4 GiB, hence a non-identity mapping was created. Unfortunately corresponding U-Boot updates were missed along with the QEMU changes and the U-Boot QEMU ppce500 PCI support has been broken since then, until this issue was fixed recently in U-Boot mainline v2021.04 release, specifically by the following U-Boot series: http://patchwork.ozlabs.org/project/uboot/list/?series=230985&state=* The cross-compilation toolchain used to build the U-Boot image is: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/10.1.0/x86_64-gcc-10.1.0-nolibc-powerpc-linux.tar.xz Signed-off-by: Bin Meng Signed-off-by: David Gibson --- diff --git a/pc-bios/u-boot.e500 b/pc-bios/u-boot.e500 index 732660f348f..d2e29f81d64 100644 Binary files a/pc-bios/u-boot.e500 and b/pc-bios/u-boot.e500 differ diff --git a/roms/u-boot b/roms/u-boot index d3689267f92..b46dd116ce0 160000 --- a/roms/u-boot +++ b/roms/u-boot @@ -1 +1 @@ -Subproject commit d3689267f92c5956e09cc7d1baa4700141662bff +Subproject commit b46dd116ce03e235f2a7d4843c6278e1da44b5e1
