Patch that builds, but haven't tested on an actual board (do have rpi2
and rpi3b+ could test sometime):

Which leads me to wonder, why have the name and description argument at
all, when you could just inherit and set the name, like done with the
boneblack?

(define-public u-boot-am335x-boneblack
  (let ((base (make-u-boot-package "am335x_evm" "arm-linux-gnueabihf")))
    (package
      (inherit base)
      (name "u-boot-am335x-boneblack")
      (description "U-Boot is a bootloader used mostly for ARM
boards. It also initializes the boards (RAM etc).
...


And of course, thanks for working on this! :)
