The Marvell Armada 3700 SoC includes an SPI controller. This controller supports up to 4 SPI slave devices, with dedicated chip selects, CPIO or FIFO mode with DMA or CPU transfers and different SPI transfer modes (Standard single, Dual or Quad). This set of patches adds a basic support for the CPIO mode, then it enables the FIFO mode (CPU-side only, DMA not supported yet). It also adds the required definitions of the spi nodes to the devicetree.
