Since Grant has added the coldfire-qspi driver to next-spi, here is the platform support for the parts that have qspi hardware. This sets up gpio to do the spi chip select using the default chip select pins; it should be trivial for boards that require different or additional spi chip selects to use other gpios as needed.
