spi: Add support for Armada 3700 SPI Controller
Marvell Armada 3700 SoC comprises an SPI Controller. This Controller supports up to 4 SPI slave devices, with dedicated chip selects,supports SPI mode 0/1/2 and 3, CPIO or Fifo mode with DMA transfers and different SPI transfer mode (Single, Dual or Quad). This commit adds basic driver support for FIFO mode. In this mode, dedicated registers are used to store the instruction, the address, the read mode and the data. Write and Read FIFO are used to store the outcoming or incoming data. The data FIFOs are accessible via DMA or by the CPU. Only the CPU is supported for now.
