No, there are two usable settings for spi1 and one setting for spi0.
I'm dropping this from the series since it's specific to how I wired up
the homebrew cape I use for spi testing on the Bone. I publish the
branch where all these extra "test-specific" patches (that aren't intended
to be merged) are at in the cover letter. Anybody that needs context of
how/what worked and was tested can grab them there.
