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 v3: - 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 show the number of physical address bits - 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
