I have an RBTX4927 development board in my board farm, boot-test every
bi-weekly renesas-drivers release on it, and fix kernel issues when they
appear.

Is that sufficient to keep it?

TX49xx SoCs were used in Sony LocationFree base stations, running
VxWorks. You can no longer buy them.
I'm not aware of anyone ever porting Linux to them.

I only noticed the planned removal when I saw the SPI patch was applied.
Doesn't matter for me, as SPI is only present on TX4938, not on TX4927 ;-)

Gr{oetje,eeting}s,
