The EDK2 based UEFI/ACPI had not been updated in something like 5 years.
The status is (as of about 3 weeks ago) official:

QUOTE
PROJECT DISCONTINUED

This EDK-2/ACPI UEFI firmware project is no longer maintained.

The project has been discontinued due to friction in the ACPI
standardization process. Modern U-Boot now ships with the required
facilities for booting a generic Linux distribution designed for UEFI
(using Device-Tree).

For instructions on installing Ubuntu and other UEFI-compatible
operating systems on the LX2160A using modern U-Boot, please refer to
the Official SolidRun LX2160A Software Page.
