Add OpenSBI version 0.4 as a git submodule and as a prebult binary. 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. In this case all of the code we are using from OpenSBI is BSD 2-clause as we aren't using the Kendryte code (Apache-2.0) with QEMU and libfdt is dual licensed as BSD 2-clause (and GPL-2.0+). OpenSBI isn't being linked with QEMU either it is just being included with QEMU.

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/).
|
|
|
|
- The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is
|

available at https://repo.or.cz/openhackware.git.
|
|
|
|
- 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-20190703.
|
|
|
|
- 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://git.qemu.org/git/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:
|
|

|
- 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://git.qemu.org/git/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

- 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-stable201905". The firmware binaries bundle parts
|
|
of the OpenSSL project, at git tag "OpenSSL_1_1_1b" (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.
