Okay. Does this mean I need not modify get_board_mach_type() and

Seems Jiaxun is interested in the board and is willing to help.

I have been told that Ingenic is focusing on IoT market and X1000 is
intended for IoT segment. I think that they would be selling several
100Ks of chip over the coming years. But I feel Ingenic spends time
only on maintaining their Linux port which is usually based on very
old kernel version.
