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>
- SeaBIOS (bios.bin) is the successor of pc bios. See http://www.seabios.org/ for more information. - The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios project (http://www.nongnu.org/vgabios/). - OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable firmware implementation. The goal is to implement a 100% IEEE 1275-1994 (referred to as Open Firmware) compliant firmware. The included images for PowerPC (for 32 and 64 bit PPC CPUs), Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built from OpenBIOS SVN revision 1280. - SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware implementation for certain IBM POWER hardware. The sources are at https://github.com/aik/SLOF, and the image currently in qemu is built from git tag qemu-slof-20210217. - sgabios (the Serial Graphics Adapter option ROM) provides a means for legacy x86 software to communicate with an attached serial console as if a video card were attached. The master sources reside in a subversion repository at http://sgabios.googlecode.com/svn/trunk. A git mirror is available at https://gitlab.com/qemu-project/sgabios.git. - The PXE roms come from the iPXE project. Built with BANNER_TIME 0. Sources available at http://ipxe.org. Vendor:Device ID -> ROM mapping: 8086:100e -> pxe-e1000.rom 8086:1209 -> pxe-eepro100.rom 1050:0940 -> pxe-ne2k_pci.rom 1022:2000 -> pxe-pcnet.rom 10ec:8139 -> pxe-rtl8139.rom 1af4:1000 -> pxe-virtio.rom - The sources for the Alpha palcode image is available from: https://github.com/rth7680/qemu-palcode.git - The u-boot binary for e500 comes from the upstream denx u-boot project where it was compiled using the qemu-ppce500 target. A git mirror is available at: https://gitlab.com/qemu-project/u-boot.git The hash used to compile the current version is: 2072e72 - Skiboot (https://github.com/open-power/skiboot/) is an OPAL (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can run an hypervisor OS or simply a host OS on the "baremetal" platform, also known as the PowerNV (Non-Virtualized) platform. - QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to provide virtualised drivers for PPC MacOS guests. - The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI variable store templates built from the TianoCore community's EFI Development Kit II project <https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images were built at git tag "edk2-stable202008". The firmware binaries bundle parts of the OpenSSL project, at git tag "OpenSSL_1_1_1g" (the OpenSSL tag is a function of the edk2 tag). Parts of the Berkeley SoftFloat library are bundled as well, at Release 3e plus a subsequent typo fix (commit b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit ARM. Licensing information is given in "edk2-licenses.txt". The image files are described by the JSON documents in the "pc-bios/descriptors" directory, which conform to the "docs/interop/firmware.json" schema. - OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source reference implementation of the RISC-V Supervisor Binary Interface (SBI) specifications for platform-specific firmwares executing in M-mode. For all supported platforms, OpenSBI provides several runtime firmware examples. These example firmwares can be used to replace the legacy riscv-pk bootloader and enable the use of well-known bootloaders such as U-Boot. OpenSBI is distributed under the terms of the BSD 2-clause license ("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI source code also contains code reused from other projects desribed here: https://github.com/riscv/opensbi/blob/master/ThirdPartyNotices.md. - npcm7xx_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for Nuvoton NPCM7xx BMC devices. It currently implements the bare minimum to load, parse, initialize and run boot images stored in SPI flash, but may grow more features over time as needed.
