Dear Ben Warren,

Why not enable this feature on Sequoia? Wolfgang's argument for keeping the patch out then goes away. IMHO, eval boards should have as many options enabled by default as possible, and the user then has the option to opt out.
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
