spi/bcm63xx: move register definitions into the driver Move all register definitions and structs into the driver. This allows us dropping the platform_data struct and drop any arch specific includes. Make use of different device names to identify the version of the block we have. Since we now have full control over the message width, we can drop the size check, which was broken anyway, since it never set ret to any error code. Also since we now have no arch depedendent resources, we can now allow compiling it for any arch, hidden behind COMPILE_TEST.

MIPS: BCM63XX: add support for BCM3368 Cable Modem The Broadcom BCM3368 Cable Modem SoC is extremely similar to the existing BCM63xx DSL SoCs, in particular BCM6358, therefore little effort in the existing code base is required to get it supported. This patch adds support for the following on-chip peripherals: - two UARTS - GPIO - Ethernet - SPI - PCI - NOR Flash The most noticeable difference with 3368 is that it has its peripheral register at 0xfff8_0000 we check that separately in ioremap.h. Since 3368 is identical to 6358 for its clock and reset bits, we use them verbatim.

MIPS: BCM63XX: remove duplicate spi register definitions BCM6338 and BCM6348, and BCM6358 and everything after that share the same register layout. To not have to redefine them for each new chip and keep the code size small, only use the definitions for the first chip with the certain layout.

MIPS: BCM63xx: Fix SPI message control register handling for BCM6338/6348. BCM6338 and BCM6348 have a message control register width of 8 bits, instead of 16-bits like what the SPI driver assumes right now. Also the SPI message type shift value of 14 is actually 6 for these SoCs. This resulted in transmit FIFO corruption because we were writing 16-bits to an 8-bits wide register, thus spanning on the first byte of the transmit FIFO, which had already been filed in bcm63xx_spi_fill_txrx_fifo(). Fix this by passing the message control register width and message type shift through platform data back to the SPI driver so that it can use it properly.

MIPS: BCM63xx: Add stub to register the SPI platform driver This patch adds the necessary stub to register the SPI platform driver. Since the registers are shuffled between the 4 BCM63xx CPUs supported by this SPI driver we also need to generate the internal register layout and export this layout for the driver to use it properly.
