This node is labeled as "gmac1" in mt7621.dtsi, so you don't need to redefine
/ethernet at 1e100000/mac at 1 here to be able to modify the node. Use &gmac1 {...} like you do
with spi0.
You can also drop the references to ethernet at 1e100000 and mac at 0, since you don't modify
any of their properties.

Is this the partition layout as defined in partition-table, or the runtime one from
/proc/mtd? We've noticed they can be different, and the runtime one is actually the one
that should be used in order to not erase the stock configuration.

This is the default value according to Documentation/devicetree/bindings/pci/host-generic-
pci.txt. Any particular reason you're specifying it here explicitly?

Is pcie0 used for anything? Otherwise it can probably also be disabled, or you can drop
this block to make the device DTS smaller.

Ah, so you *are* modifying gmac0! Maybe put the &gmac1 section here too, then.

Does the CPU connect to the switch by both gmac-s? If so, leave a comment so this can be
enabled once support for this arrives. Otherwise I think you could drop port at 5. You also
enable gmac1, but AFAICT it doesn't seem to be connected to anything.

This could also just go into the definition of partition at 90000 itself, but either way is
fine for me.

Missing $(Device/dsa-migration).

Is the 'pad-to 64k' required? mtdsplit can split at arbitrary boundaries, so I think the
padding here isn't very useful. The other device with FIT images on mt7621 also don't add
padding to the kernel.

This is a patch against firmware-utils, so it should be submitted separately for that
repository.
