Incidentally, the original raspberry pi linux kernel only
supported programmed i/o for spi. If the documentation for
the bcm2835 SoC had been the usual "just read the linux
driver" that most vendors consider adequate, we wouldn't have
known how to speed up the spi with dma.
I wonder how well this ESPRESSOBin board and SoC will be
documented? The kickstarter blurb lists a "host of operating
systems" they say they will support, but they're all linux.
