The MPPs 5, 7 and 12 are not used. Please drop their configuration.

Moreover, AFAIK, the board revision GPIOs are not used. I am not even
sure they hold a coherent value.

In addition, can we also set the machine ID ? Without breaking the DT
boot ? It would be nice to support the two Linux booting methods: DT
and legacy (machine ID, ATAGs). Note that the Linux kernel provided by
the LaCie stock firmware is not DT compliant.

Maybe you could simply undef CONFIG_MISC_INIT_R ?

Except the points above, the whole patch looks good to me.

Thanks,
