[U-Boot] [PATCH] board/t4240rdb: VID support

[Ying Zhang]

Hi, York,
                All the boards are required to set to Intel mode. If it’s not in Intel mode, VID is not support.
                I have a look how to do.

                Thanks.

Can software detect IR mode and support both? Or skip the vid part if the mode is not supported?

Hi, York,
I know this issue. It's occurred because the IR chip on T4RDB worked on AMD mode, it can work well on INTEL mode.
Nexcom will collect all the boards and set the IR chip to INTEL mode.
Before that, What should we do?

Thanks.

I tested it on top of b57843e68804c2d53d2cff2b8b2238e37b388faa, with two boards.
The result is the same.
