Please, provide a link to the specification that defines what XBOOTLDR is and that this GUID should be used in the commit message.

The Extended Boot Loader Partition (XBOOTLDR) is a standard defined by the Discoverable Partitions Specification (DPS) to host boot loader resources outside of the EFI System Partition. Defining this GUID (bc13c2ff-59e6-4262-a352-b275fd6f7172) allows U-Boot to correctly identify and label these partitions using the "xbootldr" shorthand.
