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
