1d2949aeb3 board/bsc9131rdb: Update default boot environment settings
BSC9131RDB has 1GB DDR.
Out of this, only 880MB is passed on to Linux via bootm_size.
Remaining
-16MB is reserved for PowerPC-DSP shared control area
-128MB is reserved for DSP private area.

Also 256MB, out of this 880MB is required for data communication between
PowerPC and DSP core.
For this bootargs are modified to pass parameter to create 1 hugetlb
page of 256MB via default_hugepagesz, hugepagesz and hugepages

087cf44fcd board/bsc9131rdb: Add targets for Sysclk 100MHz
BSC9131RDB supports Sysclk
-66MHz if jumper J16 is close (default state)
-100MHz if jumper J16 is open

Add targets
-BSC9131RDB_NAND_SYSCLK100 : for NAND boot at Sysclk 100MHz
-BSC9131RDB_SPIFLASH_SYSCLK100: for SPI boot at Sysclk 100MHz

7530d341c7 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
