But there is not a single SPI device on the Sequoia board, and if you
attach one, you have to write driver code for it that implements  the
chip  select handling and the specific device protocol. We would have
a driver included, without any  "users"  (code  that  actually  calls
these functions).

In other words, this driver is a prerequisite for  other  SPI  device
drivers  that  might  follow  later,  but as is, it's just a waste of
memory.

It would just waste memory to enable it.

Best regards,

Wolfgang Denk
