Actually, doing a full boot I get
ERROR: invalid device tree
Found EFI removable media binary efi/boot/bootarm.efi
1929216 bytes read in 92 ms (20 MiB/s)
libfdt fdt_check_header(): FDT_ERR_BADMAGIC

And if I interrupt boot and do printenv I get fdtfile=undefined so
while it fixes the detection and printing of the actual model it seems
it's too load for the device tree file logic, which now why I remember
I was looking at the show_board_info function above, the
board_late_init seems to late for the DT logic.
