roms/u-boot: Bump ppce500 u-boot to v2021.04 to fix broken pci support
When QEMU originally supported the ppce500 machine back in Jan 2014, it was created with a 1:1 mapping of PCI bus address. 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 <bmeng.cn@gmail.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
