Indeed. Fortunately not all of it, as some removals were TX4938-only.

Sorry, I'm not following the linux-mips list that closely, so I hadn't
seen them.  It's always a good idea to CC linux-kernel, and perhaps the
few people who last touched the affected files.

No, I don't have anything from the list above.
The RBTX4927 is basically my last MIPS-based system I do boot
current kernels on.

In active use, not for development:
  - Ubiquiti EdgeRouter-X (Ralink-based).

Stored in my attic:
  - NetGear WNDR4300 (AtherOS-based),
  - MikroTik Routerboard 150 (ADMtek-based, no (longer?) supported upstream),
  - NEC DDB VRC-5476 (upstream support removed 15 years ago ;-)

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.
