Overview
=========
The P1010RDB-PB is a Freescale Reference Design Board that hosts the P1010 SoC.
P1010RDB-PB is a variation of previous P1010RDB-PA board.

The P1010 is a cost-effective, low-power, highly integrated host processor
based on a Power Architecture e500v2 core (maximum core frequency 1GHz),that
addresses the requirements of several routing, gateways, storage, consumer,
and industrial applications. Applications of interest include the main CPUs and
I/O processors in network attached storage (NAS), the voice over IP (VoIP)
router/gateway, and wireless LAN (WLAN) and industrial controllers.

Switch P1010RDB-PB boot mode via software without setting DIP-switch
====================================================================
=> run boot_bank0    (boot from NOR bank0)
=> run boot_bank1    (boot from NOR bank1)
=> run boot_nand     (boot from NAND flash)
=> run boot_spi      (boot from SPI flash)
=> run boot_sd       (boot from SD card)


Frequency combination support on P1010RDB-PB
=============================================
SW1[4:7] SW5[1] SW5[5:8] SW2[2] Core(MHz) Platform(MHz) DDR(MT/s)
0101      1      1010     0       800       400		800
1001      1      1010     0       800       400		667

1001      1      1010     1       1000      400		667


Setting of pin mux
==================
Since pins multiplexing, TDM and CAN are muxed with SPI flash.
SDHC is muxed with IFC. IFC and SPI flash are enabled by default.

To enable TDM:
=> setenv hwconfig fsl_p1010mux:tdm_can=tdm
=> save;reset

To enable FlexCAN:
=> setenv hwconfig fsl_p1010mux:tdm_can=can
=> save;reset

To enable SDHC in case of NOR/NAND/SPI boot
   a) For temporary use case in runtime without reboot system
      run 'mux sdhc' in u-boot to validate SDHC with invalidating IFC.

   b) For long-term use case
      set 'esdhc' in hwconfig and save it.

To enable IFC in case of SD boot
   a) For temporary use case in runtime without reboot system
      run 'mux ifc' in u-boot to validate IFC with invalidating SDHC.

   b) For long-term use case
      set 'ifc' in hwconfig and save it.


Build images for different boot mode
====================================
First setup cross compile environment on build host
   $ export ARCH=powerpc
   $ export CROSS_COMPILE=<your-compiler-path>/powerpc-linux-gnu-

1. For NOR boot
   $ make P1010RDB-PB_NOR

2. For NAND boot

2. NAND boot
   => tftp 1000000 u-boot-nand.bin
   => nand erase 0 $filesize; nand write $loadaddr 0 $filesize
   Set SW4[1:4]= 1010 and SW3[3:4]= 01, then power on the board

3. SPI boot
   1)  cat p1010rdb-config-header.bin u-boot.bin > u-boot-spi-combined.bin

   3)  =>  sf probe 0; sf erase 0 100000; sf write 1000000 0 100000
   set SW4[1:4]= 0110 and SW3[3:4]= 00, then power on the board

4. SD boot
   1)	cat p1010rdb-config-header.bin u-boot.bin > u-boot-sd-combined.bin
   2)	=> tftp 1000000 u-boot-sd-combined.bin
   3)	=> mux sdhc
   4)	=> mmc write 1000000 0 1050
   set SW4[1:4]= 0111 and SW3[3:4]= 10, then power on the board


Boot Linux from network using TFTP on P1010RDB-PB
=================================================
Place uImage, p1010rdb.dtb and rootfs files in the TFTP download path.
	=> tftp 1000000 uImage
	=> tftp 2000000 p1010rdb.dtb
	=> tftp 3000000 rootfs.ext2.gz.uboot.p1010rdb
	=> bootm 1000000 3000000 2000000
