Odd. I was certainy able to build u-boot-am335x-boneblack from commit
6b99afeef89233b71d113a63cf04a6b4b49a4679 when it was introduced in 2019,
though it has been quite some time since I tested it...

I will take a guess that it was commit
c2c1dfdf5760873f1db86d14873f725a105f7feb which removed the "name" bit:

 (define-public u-boot-am335x-boneblack
-  (let ((base (make-u-boot-package
-               "am335x_evm" "arm-linux-gnueabihf"
-               ;; Patch out other device trees to build an image small enough
-               ;; to fit within typical partitioning schemes where the first
-               ;; partition begins at sector 2048.
-               #:configs '("CONFIG_OF_LIST=\"am335x-evm am335x-boneblack\""))))
-    (package
-      (inherit base)
-      (name "u-boot-am335x-boneblack")
