2015-04-20	spi: rb4xx: Fix set_cs logic.	Bert Vermeulen	1	-1/+1
	As it turns out, the set_cs() enable parameter refers to the logic level on the CS pin, not the state of chip selection. This broke functionality of the LEDs behind the CPLD, or at least delayed the commands until another one came in to toggle CS.

2015-04-18	spi: Add SPI driver for Mikrotik RB4xx series boards	Bert Vermeulen	1	-0/+210
	This driver mediates access between the connected CPLD and other devices on the bus. The m25p80-compatible boot flash and (some models) MMC use regular SPI, bitbanged as required by the SoC. However the SPI-connected CPLD has a two-wire mode, in which two bits are transferred per SPI clock cycle. The second bit is transmitted with the SoC's CS2 pin.
