[PATCH] Add GPIO, I2C and SPI support for the RPi BSP

[Alan Cudmore]

Sebastian,
Makes sense. I think I understand the idea a little better now, we are
using the linux uapi i2c API, but not the actual i2c bus and device driver
implementations from linux, right?

For the Pi ( and others like the Beagleboard ) we need to come up with an
i2c BSP bus driver ( similar to cadence-i2c.c/h ) then a set of i2c device
drivers to go in cpukit/dev/i2c.

Do the individual device drivers, such as cpukit/dev/i2c/gpi-nxp-pca9535.c,
resemble the equivalent linux driver?

Thanks,
Alan
