[PATCH][v2] powerpc/85xx:Add BSC9131 RDB Support

[Prabhakar Kushwaha]

BSC9131RDB is a Freescale reference design board for BSC9131 SoC.The BSC9131 is
integrated SoC that targets Femto base station market. It combines Power
Architecture e500v2 and DSP StarCore SC3850 core technologies with MAPLE-B2F
baseband acceleration processing elements.

The BSC9131 SoC includes the following function and features:
    . Power Architecture subsystem including a e500 processor with 256-Kbyte shared
      L2 cache
    . StarCore SC3850 DSP subsystem with a 512-Kbyte private L2 cache
    . The Multi Accelerator Platform Engine for Femto BaseStation Baseband
      Processing (MAPLE-B2F)
    . A multi-standard baseband algorithm accelerator for Channel Decoding/Encoding,
      Fourier Transforms, UMTS chip rate processing, LTE UP/DL Channel processing,
      and CRC algorithms
    . Consists of accelerators for Convolution, Filtering, Turbo Encoding,
      Turbo Decoding, Viterbi decoding, Chiprate processing, and Matrix Inversion
      operations
    . DDR3/3L memory interface with 32-bit data width without ECC and 16-bit with
      ECC, up to 400-MHz clock/800 MHz data rate
    . Dedicated security engine featuring trusted boot
    . DMA controller
    . OCNDMA with four bidirectional channels
    . Interfaces
    . Two triple-speed Gigabit Ethernet controllers featuring network acceleration
      including IEEE 1588. v2 hardware support and virtualization (eTSEC)
    . eTSEC 1 supports RGMII/RMII
    . eTSEC 2 supports RGMII
    . High-speed USB 2.0 host and device controller with ULPI interface
    . Enhanced secure digital (SD/MMC) host controller (eSDHC)
    . Antenna interface controller (AIC), supporting three industry standard
      JESD207/three custom ADI RF interfaces (two dual port and one single port)
      and three MAXIM's MaxPHY serial interfaces
    . ADI lanes support both full duplex FDD support and half duplex TDD support
    . Universal Subscriber Identity Module (USIM) interface that facilitates
      communication to SIM cards or Eurochip pre-paid phone cards
    . TDM with one TDM port
    . Two DUART, four eSPI, and two I2C controllers
    . Integrated Flash memory controller (IFC)
    . TDM with 256 channels
    . GPIO
    . Sixteen 32-bit timers

The DSP portion of the SoC consists of DSP core (SC3850) and various
accelerators pertaining to DSP operations.

 BSC9131RDB Overview
 ----------------------
     BSC9131 SoC
     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

 Linux runs on e500v2 core and access some DSP peripherals like AIC

 Note:   Name of PSC9131 has been changed to BSC9131 because of new nomenclature
	Please reject earlier patch"powerpc/85xx:Add PSC9131 RDB Support"
	  http://patchwork.ozlabs.org/patch/146349/

 Beased on http://git.kernel.org/pub/scm/linux/kernel/git/galak/powerpc.git
	    branch master

 Changes for v2: 
 	- Change board file name as bsc913x_rdb.c
	- Removed all I2C's board device. A separate patch will be send.
	- Combined SPI's 2 RFS partition into single RFS parition
	- Added SEC/crypto node in dts
