Hi Arnd,

Yes, it was removed and so far I've received 0 complaints/questions 
about it.
Even in the years before removal, it hardly ever generated any fuzz.
(I guess I was nearly the only one judging by mail history ..)

The board I used for working on this target also became EOL upstream, as 
the SoC used on it also EOL'd at Cavium.

I tried 2 times to still add support for it using kernel 5.4 last 
summer, but supporting some
pheripherals mentioned in the boardfile resulted in devicetree horror.
(It's me lacking DT knowledge here)

All these issues, combined with EOL status and an extremely low audience 
resulted in final removal.

Regards,

Koen
