Tom Rini 6e7df1d151 global: Finish CONFIG -> CFG migration
At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

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 eff40000 efffffff
	=> cp.b 1000000 eff40000 c0000

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 eff00000 eff3ffff
	=> cp.b 1000000 eff00000 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 8 672

4. Program FMAN Firmware ucode
	=> tftp 1000000 ucode.bin
	=> mmc write 1000000 690 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'

Device tree support and how to enable it for different configs
--------------------------------------------------------------
Device tree support is available for p2041rdb for below mentioned boot,
1. NOR Boot
2. NAND Boot
3. SD Boot
4. SPIFLASH Boot

To enable device tree support for other boot, below configs need to be
enabled in relative defconfig file,
1. CONFIG_DEFAULT_DEVICE_TREE="p2041rdb" (Change default device tree name if required)
2. CONFIG_OF_CONTROL
3. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at
   CFG_RESET_VECTOR_ADDRESS - 0xffc

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
