[PATCH 00/38] x86: Use qemu-x86_64 to boot EFI installers

[Simon Glass]

This series adds various minor features so that qemu-x86_64 can boot the
Ubuntu 2022.04 installer using a virtio device:

    qemu-system-x86_64 -M pc -drive format=raw,file=root.img
        -bios /tmp/b/qemu-x86_64/u-boot.rom
        -drive if=virtio,file=ubuntu-22.04.2-desktop-amd64.iso
        -smp 4 -m 4G -serial mon:stdio

The main changes include:
- Enable video in SPL while running in 32-bit mode
- Drop the duplicate ACPI tables with EFI
- Support PCI autoconfig in SPL
- Support FAT on a CDROM filesystem
- Improved bootstd rules around device tree and efi_set_bootdev()

There are also quite a number of minor tweaks and fixes to make things
easier to use.

This series is based on an older version of the SPL-video series from
Nikhil M Jain. It is available at u-boot-dm/bryc-working
