The current UPL spec[1] has been tidied up and improved over the last year, since U-Boot's original UPL support was written.
This series addresses various issues, with a goal of having U-Boot boot EDK2.
There is still more work to do, but this series gets to the point (on QEMU) where the ACPI tables are required. Further work will be needed to relocate the tables out of the QEMU firmware-filesystem.
