Thanks for the information. I tried and it works.
However it seems using uboot fdt commands is much complicated than kernel
command line way as i did in this patch.
We probably may would rather using add more board dts way if can not accept this patch series.
I already replied that concern in last mail, can you help check it and provide suggestions?
