powerpc/mpc85xx:Add BSC9131 RDB Support
BSC9131RDB is a Freescale reference design board for BSC9131 SoC. BSC9131 SOC
is an integrated device that targets Femto base station market. It combines
Power Architecture e500v2 and DSP StarCore SC3850 core technologies with
MAPLE-B2F baseband acceleration processing elements
BSC9131RDB Overview
-----------------
-1Gbyte DDR3 (on board DDR)
-128Mbyte 2K page size NAND Flash
-256 Kbit M24256 I2C EEPROM
-128 Mbit SPI Flash memory
-USB-ULPI
-eTSEC1: Connected to RGMII PHY
-eTSEC2: Connected to RGMII PHY
-DUART interface: supports one UARTs up to 115200 bps for console display
Apart from the above it also consists various peripherals to support DSP
functionalities.
This patch adds support for mainly Power side functionalities and peripherals
