Hi Troy,

> + };

This partition ends at 0x800000. On the CoM260 with EDK2, 0x700000 to
0x7c0000 holds the variable store (NVRAM and FTW), so reflashing this
partition from Linux would erase it.

I think we could split it like this:

uboot@210000 {
reg = <0x210000 0x4f0000>;
};

var@700000 {
reg = <0x700000 0xc0000>;
read-only;
};

What do you think?

The Pico-ITX node also uses 0x5f0000, but I think it should be modified to split out the var part too if it makes sense here.

The Pico-ITX flash node also has vcc-supply = <&aldo2>.
Shouldn't this be present here as well?

The rest of the patch LGTM and matches what we have already tested in the Ubuntu kernel.

Thanks,
Sarah
