Should I register machine? I develop DT only:
"NOTE 1:If you are developing a DT-only platform, you do not need to register a machine type for it.
Please do not register a machine type. Thanks."
Do I need this MACH_TYPE_* at all?

No, this is no pointer modifier, it's together %pM and it prints ethaddr like this: 02:22:23:15:86:a5.

Yes, I knew that, but I have looked many other board files and they use both GPIO and PIO in one file.
If is necessary I'll re-base it to PIO.

Is that true? I thought use one copy env, if not then use default.
