It will be good if you comment out for the MPPs that you are configuring

Same here, pls explain the each bit and associated LED used for

It's better if you shift "x_bootcmd_ethernet" to below line to make it more readable

Comments need to be in lined with used PHY

Apart from above cosmetic changes, the patch looks okay to me
