The code base adds P1 & P2 RDB platforms support.
The folder and file names can cater to future SOCs of P1/P2 family.
P1 & P2 processors are 85xx platforms, part of Freescale QorIQ series.

Tested following on P2020RDB:
1. eTSECs
2. DDR, NAND, NOR, I2C.

+Overview
+--------
+P2020RDB is a Low End Dual core platform supporting the P2020 processor
+of QorIQ series. P2020 is an e500 based dual core SOC.
+
+Building U-boot
+-----------
+To build the u-boot for P2020RDB:
+       make P2020RDB_config
+       make
+
+NOR Flash Banks
+-----------
+RDB board for P2020 has two flash banks. They are both present on boot.
+
+Booting by default is always from the boot bank at 0xef00_0000.
+
+Memory Map
+----------
+0xef00_0000 - 0xef7f_ffff      Alernate bank           8MB
+0xe800_0000 - 0xefff_ffff      Boot bank               8MB
+
+0xef78_0000 - 0xef7f_ffff      Alternate u-boot address        512KB
+0xeff8_0000 - 0xefff_ffff      Boot u-boot address             512KB
+
+Switch settings to boot from the NOR flash banks
+------------------------------------------------
+SW4[8]=0 default NOR Flash bank
+SW4[8]=1 Alternate NOR Flash bank
+
+Flashing Images
+---------------
+To place a new u-boot image in the alternate flash bank and then boot
+with that new image temporarily, use this:
+       tftp 1000000 u-boot.bin
+       erase ef780000 ef7fffff
+       cp.b 1000000 ef780000 80000
+
+Now to boot from the alternate bank change the SW4[8] from 0 to 1.
+
+To program the image in the boot flash bank:
+       tftp 1000000 u-boot.bin
+       protect off all
+       erase eff80000 ffffffff
+       cp.b 1000000 eff80000 80000
+
+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 p2020rdb.dts > p2020rdb.dtb
+
+Likely, that .dts file will come from here;
+
+       linux-2.6/arch/powerpc/boot/dts/p2020rdb.dts
+
+Booting Linux
+-------------
+Place a linux uImage in the TFTP disk area.
+
+       tftp 1000000 uImage.p2020rdb
+       tftp 2000000 rootfs.ext2.gz.uboot
+       tftp c00000 p2020rdb.dtb
+       bootm 1000000 2000000 c00000
+
+Implementing AMP(Asymmetric MultiProcessing)
+---------------------------------------------
+1. Build kernel image for core0:
+
+       a. $ make 85xx/p1_p2_rdb_defconfig
+
+       b. $ make menuconfig
+          - un-select "Processor support"->
+               "Symetric multi-processing support"
+
+       c. $ make uImage
+
+       d. $ cp arch/powerpc/boot/uImage /tftpboot/uImage.core0
+
+2. Build kernel image for core1:
+
+       a. $ make 85xx/p1_p2_rdb_defconfig
+
+       b. $ make menuconfig
+          - Un-select "Processor support"->
+               "Symetric multi-processing support"
+          - Select "Advanced setup" ->
+               "Prompt for advanced kernel configuration options"
+               - Select
+                       "Set physical address where the kernel is loaded"
+                       and set it to 0x20000000, asssuming core1 will
+                       start from 512MB.
+               - Select "Set custom page offset address"
+               - Select "Set custom kernel base address"
+               - Select "Set maximum low memory"
+          - "Exit" and save the selection.
+
+       c. $ make uImage
+
+       d. $ cp arch/powerpc/boot/uImage /tftpboot/uImage.core1
+
+3. Create dtb for core0:
+
+       $ dtc -I dts -O dtb -f -b 0
+                arch/powerpc/boot/dts/p2020rdb_camp_core0.dts >
+                /tftpboot/p2020rdb_camp_core0.dtb
+
+4. Create dtb for core1:
+
+       $ dtc -I dts -O dtb -f -b 1
+                arch/powerpc/boot/dts/p2020rdb_camp_core1.dts >
+                /tftpboot/p2020rdb_camp_core1.dtb
+
+5. Bring up two cores separately:
+
+       a. Power on the board, under u-boot prompt:
+               => setenv <serverip>
+               => setenv <ipaddr>
+               => setenv bootargs root=/dev/ram rw console=ttyS0,115200
+       b. Bring up core1's kernel first:
+               => setenv bootm_low 0x20000000
+               => setenv bootm_size 0x10000000
+               => tftp 21000000 uImage.core1
+               => tftp 22000000 ramdiskfile
+               => tftp 20c00000 p2020rdb_camp_core1.dtb
+               => interrupts off
+               => bootm start 21000000 22000000 20c00000
+               => bootm loados
+               => bootm ramdisk
+               => bootm fdt
+               => fdt boardsetup
+               => fdt chosen $initrd_start $initrd_end
+               => bootm prep
+               => cpu 1 release $bootm_low - $fdtaddr -
+       c. Bring up core0's kernel(on the same u-boot console):
+               => setenv bootm_low 0
+               => setenv bootm_size 0x20000000
+               => tftp 1000000 uImage.core0
+               => tftp 2000000 ramdiskfile
+               => tftp c00000 p2020rdb_camp_core0.dtb
+               => bootm 1000000 2000000 c00000
+
+Please note only core0 will run u-boot, core1 starts kernel directly
+after "cpu release" command is issued.
