Fabiano Rosas 35ed01ba54 optionrom: Remove build-id section
Our linker script for optionroms specifies only the placement of the
.text section, leaving the linker free to place the remaining sections
at arbitrary places in the file.

Since at least binutils 2.39, the .note.gnu.build-id section is now
being placed at the start of the file, which causes label addresses to
be shifted. For linuxboot_dma.bin that means that the PnP header
(among others) will not be found when determining the type of ROM at
optionrom_setup():

(0x1c is the label _pnph, where the magic "PnP" is)

$ xxd /usr/share/qemu/linuxboot_dma.bin | grep "PnP"
00000010: 0000 0000 0000 0000 0000 1c00 2450 6e50  ............$PnP

$ xxd pc-bios/optionrom/linuxboot_dma.bin | grep "PnP"
00000010: 0000 0000 0000 0000 0000 4c00 2450 6e50  ............$PnP
                                   ^bad

Using a freshly built linuxboot_dma.bin ROM results in a broken boot:

  SeaBIOS (version rel-1.16.2-0-gea1b7a073390-prebuilt.qemu.org)
  Booting from Hard Disk...
  Boot failed: could not read the boot disk

  Booting from Floppy...
  Boot failed: could not read the boot disk

  No bootable device.

We're not using the build-id section, so pass the --build-id=none
option to the linker to remove it entirely.

Note: In theory, this same issue could happen with any other
section. The ideal solution would be to have all unused sections
discarded in the linker script. However that would be a larger change,
specially for the pvh rom which uses the .bss and COMMON sections so
I'm addressing only the immediate issue here.

- 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-20220719.

- VOF (Virtual Open Firmware) is a minimalistic firmware to work with
  -machine pseries,x-vof=on. When enabled, the firmware acts as a slim shim and
  QEMU implements parts of the IEEE 1275 Open Firmware interface.

- 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-stable202302". The firmware binaries bundle parts
  of the OpenSSL project, at git tag "OpenSSL_1_1_1s" (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:

- 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. The source code is available at:
  https://github.com/google/vbootrom
