Both have the same representation in the resulting DTB, but this is a list, so:
devices = <&fwconcat0>, <&fwconcat1>;

Since this is where the bootloader is going to look for a kernel, I'm pretty
sure the
kernel will need to be contained entirely in this partition (or you need a
kernel loader).
That would mean it must fit inside 6016 kiB.

So you will probably need two check-size calls here:
IMAGE/sysupgrade.bin := append-kernel | check-size 6016k | \
append-rootfs | pad-rootfs | check-size | append-metadata
Side note: You're definitely not the only one with flash constraints on mt76x8,
so I
wonder if a small-flash configuration/package selection would make sense.
Best,
Sander
