>
> Update igep00x0 code with the following features:
> - Add board and revision detection for the boards:
> - IGEP0020-RF
> - IGEP0020-RC
> - IGEP0030-RG
> - IGEP0030-RE
> - Merge IGEP0020 and IGEP0030 mux tables
> - Add suport to use GPIO_126, GPIO_127 and GPIO_129
> - board_name and board_rev environment variables display board and
> revision informations
> - Move dtb name selection from code to boot script
>

> Changes:
> -v2: Move dtb name selection from code to boot script
> Use board_rev to hold board revision
