Hi Ion (sorry just noticed you've been signing Ion, but your email says Tony),


Yeah, I am Ion Alexandru Beza, always was and be.
That Tony was assigned to me by gmail, I don't know why.
(let's not debug this)

No - it will work fine for the last case - worst case is that you just
have to waste a pin for the chip select which doesn't get connected to
anything.

omap2_mcspi.c might work on the OMAP side (and Gumstix) of the SPI.

The first problem remains detection of 1278 during the word "booting" shown in the log of the boot
file, at init, based on .modalias="ads1278" in board-overo.c.
