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
Changes in v5:
- Make mtrr_type_name[] static
- Fix 'abrievated' typo

- Add a comment about QFW putting its tables up high
- Add a comment that the bloblist is always in high memory
- Use "gpio" for log return
- Use QEMU instead of qemu
- Drop patch 'Show the number of physical address bits'
Changes in v4:
- Drop patch "video: Allow building video drivers for SPL"
- Drop use of video in SPL
Changes in v3:
- Fix invalid commit IDs obtained from another branch
- Add a tag name for the blob
- Add new patch to refactor table-writing code a ltitle
- Adjust the code to handle qemu writing a pointer to tables in memory
Changes in v2:
- Add new patch with docs for mtrr command
- Add docs to board_init_f_r() too
- Fix BINS typo
- Drop the Ooops string
- Drop ** in strings and use log_err() for messages
- Use log_warning() for the warning
- Handle the case where the tables are in the bloblist
- Add new patch to convert some debug statements to use logging
- Add new patch to support Micron memory
- Add new patch to make sure that the LPC is active before SDRAM init
- Add new patch to support outputing function names in SPL
- Drop patch to set high bits of the mtrr base register, for now
- Bring in to qemu series
- Rebase to -next
- Drop unused of_match
- Fix Boschs typo
- Rename bochs_init_linear_fb() function to drop 'linear'
- Fix uninited variable
