   1- SeaBIOS (bios.bin) is the successor of pc bios.
   2  See http://www.seabios.org/ for more information.
   3
   4- The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios
   5  project (http://www.nongnu.org/vgabios/).
   6
   7- OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable
   8  firmware implementation. The goal is to implement a 100% IEEE
   9  1275-1994 (referred to as Open Firmware) compliant firmware.
  10  The included images for PowerPC (for 32 and 64 bit PPC CPUs),
  11  Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built
  12  from OpenBIOS SVN revision 1280.
  13
  14- SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware
  15  implementation for certain IBM POWER hardware.  The sources are at
  16  https://github.com/aik/SLOF, and the image currently in qemu is
  17  built from git tag qemu-slof-20210217.
  18
  19- sgabios (the Serial Graphics Adapter option ROM) provides a means for
  20  legacy x86 software to communicate with an attached serial console as
  21  if a video card were attached.  The master sources reside in a subversion
  22  repository at http://sgabios.googlecode.com/svn/trunk.  A git mirror is
  23  available at https://gitlab.com/qemu-project/sgabios.git.
  24
  25- The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
  26  Sources available at http://ipxe.org.  Vendor:Device ID -> ROM mapping:
  27
  28        8086:100e -> pxe-e1000.rom
  29        8086:1209 -> pxe-eepro100.rom
  30        1050:0940 -> pxe-ne2k_pci.rom
  31        1022:2000 -> pxe-pcnet.rom
  32        10ec:8139 -> pxe-rtl8139.rom
  33        1af4:1000 -> pxe-virtio.rom
  34
  35- The sources for the Alpha palcode image is available from:
  36  https://github.com/rth7680/qemu-palcode.git
  37
  38- The u-boot binary for e500 comes from the upstream denx u-boot project where
  39  it was compiled using the qemu-ppce500 target.
  40  A git mirror is available at: https://gitlab.com/qemu-project/u-boot.git
  41  The hash used to compile the current version is: 2072e72
  42
  43- Skiboot (https://github.com/open-power/skiboot/) is an OPAL
  44  (OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
  45  run an hypervisor OS or simply a host OS on the "baremetal"
  46  platform, also known as the PowerNV (Non-Virtualized) platform.
  47
  48- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
  49  provide virtualised drivers for PPC MacOS guests.
  50
  51- The "edk2-*.fd.bz2" images are platform firmware binaries and matching UEFI
  52  variable store templates built from the TianoCore community's EFI Development
  53  Kit II project
  54  <https://github.com/tianocore/tianocore.github.io/wiki/EDK-II>. The images
  55  were built at git tag "edk2-stable202008". The firmware binaries bundle parts
  56  of the OpenSSL project, at git tag "OpenSSL_1_1_1g" (the OpenSSL tag is a
  57  function of the edk2 tag). Parts of the Berkeley SoftFloat library are
  58  bundled as well, at Release 3e plus a subsequent typo fix (commit
  59  b64af41c3276f97f0e181920400ee056b9c88037), as an OpenSSL dependency on 32-bit
  60  ARM. Licensing information is given in "edk2-licenses.txt". The image files
  61  are described by the JSON documents in the "pc-bios/descriptors" directory,
  62  which conform to the "docs/interop/firmware.json" schema.
  63
  64- OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
  65  reference implementation of the RISC-V Supervisor Binary Interface (SBI)
  66  specifications for platform-specific firmwares executing in M-mode. For all
  67  supported platforms, OpenSBI provides several runtime firmware examples.
  68  These example firmwares can be used to replace the legacy riscv-pk bootloader
  69  and enable the use of well-known bootloaders such as U-Boot.
  70  OpenSBI is distributed under the terms of the BSD 2-clause license
  71  ("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI
  72  source code also contains code reused from other projects desribed here:

  75- npcm7xx_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for Nuvoton
  76  NPCM7xx BMC devices. It currently implements the bare minimum to load, parse,
  77  initialize and run boot images stored in SPI flash, but may grow more
  78  features over time as needed. The source code is available at:
  79  https://github.com/google/vbootrom
