I proposed this patch for a long time, but it was rejected by Wolfgang.

I am seeing multiple companies implementing small CPU modules
incorporating CPU + FPGA, and the customers will adopt the FPGA
code for their own need, and then they need to create a new machine id.

Having such a patch will allow people in this situation to use the 
U-Boot on the board without recompilation.
