As per current implemenetation, default value of board env is based on board filename i.e ls2080ardb.
With distro support changes, this env is used to decide upon kernel dtb which is different for other SoCs (ls2088a, ls2081a) combination supported with this board.
Add support to modify board env based on SoC type
Please point me to where environmental variable "board" is used for distro boot. I only see it for PXE.

Please double check this. I think "setenv" has been replaced by "env_set" as of commit 382bee57f.
