The commit log for the patch is not that correct. I miss understanding dcd skip previously.
After set dcd_skip to true, non-spl version uboot could not be started.

I do not see log from SPL part,

My log:

I do not have patch currently. You could fix it if you would like to do.

The code default switch to SPL, the non-spl uboot not supported based on this patch.
The commit log is wrong, but I do not prefer to revert it. A new option could be provided
to let people choose dcd_skip to true or false.

Thanks,
Peng.
