+2. 800/400/667
+
+Boot Methods Supported
+-----------------------
+1. NAND Flash
+2. SPI Flash
+
+Default Boot Method
+--------------------
+NAND boot
+
+Building U-boot
+--------------
+To build the u-boot for BSC9131RDB:
+1. NAND Flash with sysclk 66MHz(J16 on RDB closed, default)
+	make BSC9131RDB_NAND
+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
+
+Memory map
+-----------
+ 0x0000_0000	0x7FFF_FFFF	DDR			1G cacheable
+ 0xA0000000	0xBFFFFFFF	Shared DSP core L2/M2 space	512M
+ 0xC100_0000	0xC13F_FFFF	MAPLE-2F		4M
+ 0xC1F0_0000	0xC1F3_FFFF	PA SRAM Region 0	256K
+ 0xC1F8_0000	0xC1F9_FFFF	PA SRAM Region 1	128K
+ 0xFED0_0000	0xFED0_3FFF	SEC Secured RAM		16K
+ 0xFEE0_0000	0xFEE0_0FFF	DSP Boot ROM		4K
+ 0xFF60_0000	0xFF6F_FFFF 	DSP CCSR		1M
+ 0xFF70_0000	0xFF7F_FFFF	PA CCSR			1M
+ 0xFF80_0000	0xFFFF_FFFF	Boot Page & NAND Buffer 8M
+
+DDR Memory map
+---------------
+ 0x0000_0000	0x36FF_FFFF	Memory passed onto Linux
+ 0x3700_0000	0x37FF_FFFF	PowerPC-DSP shared control area
+ 0x3800_0000	0x4FFF_FFFF	DSP Private area
+
+ Out of 880M, passed onto Linux, 1hugetlb page of 256M is reserved for
+ data communcation between PowerPC and DSP core.
+ Rest is PowerPC private area.
+
+Flashing Images
+---------------
+To place a new u-boot image in the NAND flash and then boot
+with that new image temporarily, use this:
+	tftp 1000000 u-boot-nand.bin
+	nand erase 0 100000
+	nand write 1000000 0 100000
+	reset
+
+Using the Device Tree Source File
+---------------------------------
+To create the DTB (Device Tree Binary) image file,
+use a command similar to this:
+
+	dtc -b 0 -f -I dts -O dtb bsc9131rdb.dts > bsc9131rdb.dtb
+
+Likely, that .dts file will come from here;
+
+	linux-2.6/arch/powerpc/boot/dts/bsc9131rdb.dts
+
+Booting Linux
+-------------
+Place a linux uImage in the TFTP disk area.
+
+	tftp 1000000 uImage
+	tftp 2000000 rootfs.ext2.gz.uboot
+	tftp c00000 bsc9131rdb.dtb
+	bootm 1000000 2000000 c00000
