Is this function really needed? It is always empty.

It seems you don't make any use of board_name and board_rev.
Are they really needed?

This is not needed after you switch to distro config. This root= information is distro specific and should not be part of the standard config.
Please look at include/configs/wandboard.h for example for a much more compact example.

Not used with distro config.

This is not needed.
