Can you handle the mask into this struct aswell like
https://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git/commit/?h=v5.2/drivers&id=dce47aed20c7de3ee2011b7a63e67f08e9dcfb5e
 ?

You should also add the new IDs like in :
https://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git/commit/?h=v5.2/drivers&id=65f80df58eb770b2b687c35142c113d1ad6fa415

Can you also show the board model from DT like the original show_board_info() ?

Looks good, but can you move this code to a separate C file, like board-info.c ?
