+Overview
+=========
+The P2041 Processor combines four Power Architecture processor cores
+with high-performance datapath acceleration architecture(DPAA), CoreNet
+fabric infrastructure, as well as network and peripheral bus interfaces
+required for networking, telecom/datacom, wireless infrastructure, and
+military/aerospace applications.
+
+P2041RDB board is a quad core platform supporting the P2041 processor
+of QorIQ DPAA series.
+
+Boot from NOR flash
+===================
+1. Build image
+	make P2041RDB_config
+	make all
+
+2. Program image
+	=> tftp 1000000 u-boot.bin
+	=> protect off all
+	=> erase eff80000 efffffff
+	=> cp.b 1000000 eff80000 80000
+
+3. Program RCW
+	=> tftp 1000000 rcw.bin
+	=> protect off all
+	=> erase e8000000 e801ffff
+	=> cp.b 1000000 e8000000 50
+
+4. Program FMAN Firmware ucode
+	=> tftp 1000000 ucode.bin
+	=> protect off all
+	=> erase ef000000 ef0fffff
+	=> cp.b 1000000 ef000000 2000
+
+5. Change DIP-switch
+	SW1[1-5] = 10110
+	Note: 1 stands for 'on', 0 stands for 'off'
+
+Boot from SDCard
+===================
+1. Build image
+	make P2041RDB_SDCARD_config
+	make all
+
+2. Generate PBL imge
+   Use PE tool to produce a image used to be programed to
+   SDCard which contains RCW and U-Boot image.
+
+3. Program the PBL image to SDCard
+	=> tftp 1000000 pbl_sd.bin
+	=> mmcinfo
+	=> mmc write 1000000 8 441
+
+4. Program FMAN Firmware ucode
+	=> tftp 1000000 ucode.bin
+	=> mmc write 1000000 46a 10
+
+5. Change DIP-switch
+	SW1[1-5] = 01100
+	Note: 1 stands for 'on', 0 stands for 'off'
+
+Boot from SPI flash
+===================
+1. Build image
+	make P2041RDB_SPIFLASH_config
+	make all
+
+2. Generate PBL imge
+   Use PE tool to produce a image used to be programed to
+   SPI flash which contains RCW and U-Boot image.
+
+3. Program the PBL image to SPI flash
+	=> tftp 1000000 pbl_spi.bin
+	=> spi probe 0
+	=> sf erase 0 100000
+	=> sf write 1000000 0 $filesize
+
+4. Program FMAN Firmware ucode
+	=> tftp 1000000 ucode.bin
+	=> sf erase 110000 10000
+	=> sf write 1000000 110000 $filesize
+
+5. Change DIP-switch
+	SW1[1-5] = 10100
+	Note: 1 stands for 'on', 0 stands for 'off'
+
+CPLD command
+============
+The CPLD is used to control the power sequence and some serdes lane
+mux function.
+
+cpld reset			 - hard reset to default bank
+cpld reset altbank		 - reset to alternate bank
+cpld lane_mux <lane> <mux_value> - set multiplexed lane pin
+		lane 6: 0 -> slot1 (Default)
+			1 -> SGMII
+		lane a: 0 -> slot2 (Default)
+			1 -> AURORA
+		lane c: 0 -> slot2 (Default)
+			1 -> SATA0
+		lane d: 0 -> slot2 (Default)
+			1 -> SATA1
+
+Using the Device Tree Source File
+=================================
+To create the DTB (Device Tree Binary) image file, use a command
+similar to this:
+	dtc -O dtb -b 0 -p 1024 p2041rdb.dts > p2041rdb.dtb
+
+Or use the following command:
+	{linux-2.6}/make p2041rdb.dtb ARCH=powerpc
+
+then the dtb file will be generated under the following directory:
+	{linux-2.6}/arch/powerpc/boot/p2041rdb.dtb
+
+Booting Linux
+=============
+Place a linux uImage in the TFTP disk area.
+	tftp 1000000 uImage
+	tftp 2000000 rootfs.ext2.gz.uboot
+	tftp 3000000 p2041rdb.dtb
+	bootm 1000000 2000000 3000000
