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

Building U-boot
--------------
To build the u-boot for BSC9131RDB:
-1. NAND Flash
+1. NAND Flash with sysclk 66MHz(J16 on RDB closed, default)
make BSC9131RDB_NAND
-2. SPI Flash
+2. NAND Flash with sysclk 100MHz(J16 on RDB open)
+ make BSC9131RDB_NAND_SYSCLK100
+3. SPI Flash with sysclk 66MHz(J16 on RDB closed, default)
make BSC9131RDB_SPIFLASH
+4. SPI Flash with sysclk 100MHz(J16 on RDB open)
+ make BSC9131RDB_SPIFLASH_SYSCLK100
