Some devices have multiple partition types available on the same media. It is sometimes useful to see these to check that everything is working correctly.
Provide a way to manually set the partition-table type, avoiding the auto-detection process.
Do you have an example image where we get it wrong?
Linux does not need that. What is different in our table type priorities to Linux?
I am not yet convinced we need to set this manually.
There is an example in the documentation I added. That is using the Ubuntu 22.04 ISO. Can you give it a try?
Linux would mount this as iso9660.
U-Boot lacks a driver for this file system.
There is no need to mount the file as CD-ROM drive. You could mount it as virtio drive instead or as USB. Then U-Boot can read the EFI partition with sector size 512.
Computers nowadays are installed from USB. Most workstation cases don't foresee optical drives anymore.
Best regards

You can also try it with a CDROM drive, something like:
qemu-system-x86_64 -drive format=raw,file=root.img -bios /tmp/b/qemu-x86_64/u-boot.rom -cdrom ubuntu-22.04.2-desktop-amd64.iso -hdb fat:rw:/home/sglass/cosarm/win/seabios -nographic -m 4096
