With CONFIG_OF_ALL_DTBS=y, as set by eg. allmodconfig, we see lots of

Unfortunately yes. This patch will break uboot code in Meraki MX60(W) / MX60.

Backstory: There are two version of the Meraki MX60. The MX60
and the MX60W. The difference is that the MX60W has a populated
mini-pcie slot on the PCB for a >W<ireless card.
That said, this is not earth shattering.
I'm happy to revert that hunk if you think any one is actually booting
mainline on those.
The MX60(W) or APM82181 in general?
The APM82181 devices run really well on the kernel 5.8. The APM82181
had some bitrot and missing pieces. But I started at around 4.4 with
upstreaming various bits and stuff. For proof, I can post a bootlog from
my MyBook Live dev station running my mbl-debian on this weekend:
<https://github.com/chunkeey/mbl-debian>.
Here is the MyBook Live's Single Bootlog for 5.9-rc4.
