You can control boot targets using the boot_targets env var and boot
methods using the bootmeths env var.

For normal generic use the full bootstd commands should not be needed,
do you have special scripting requirements that require access to full
bootstd commands?

All rockchip boards use standard boot, this only enables full commands
for one particular board, why is this board special? Or is there merit
to imply enable of full commands for all rockchip boards?

Jonas
