The P1023RDS board is the reference board for the P1023 SoC.
Add support for booting it from NOR or NAND, with fixed 2G of DDR, PCIe,
UART, I2C, etc.

+Overview
+--------
+The P1023 process includes a performance optimized implementation of the
+QorIQ data Path Acceleration Architecture (DPAA). This architecture
+provides the infrastructure to support simplified sharing of networking
+interfaces and accelerators by multiple CPU cores. P1023 is an e500 based
+dual core SOC.
+
+P1023RDS board is a Low End Dual core platform supporting the P1023
+processor of QorIQ series.
+
+Building U-boot
+---------------
+To build the u-boot for P1023RDS:
+Configure to NOR boot:
+ make P1023RDS_config
+Configure to NAND boot:
+ make P1023RDS_NAND_config
+Build:
+ make
+
+Board Switches
+--------------
+Most switches on the board should not be changed. The most frequent
+user-settable switches on the board are used to configure
+the flash banks.
+
+J4: all open
+
+Default NOR flash boot switch setting:
+ Sw3[1:8]: off on on off on on off off

+0x8000_0000 0xbfff_ffff PCI Express Mem 1G non-cacheable
+0xc000_0000 0xdfff_ffff PCI 512M non-cacheable
+0xe100_0000 0xe3ff_ffff PCI IO range 4M non-cacheable

+
+Flashing u-boot Images
+---------------
+To program the image in the boot flash bank:
+NOR flash boot:
+ => tftp 1000000 u-boot.bin
+ => protect off all
+ => erase eff80000 efffffff
+ => cp.b 1000000 eff80000 80000
+
+NAND flash boot:
+ => tftp 1000000 u-boot-nand.bin
+ => nand erase 0 80000
+ => nand write 1000000 0 80000
+
+Firmware ucode location
+---------------------------------
+Microcode(ucode) to FMAN's IRAM is needed to make FMAN Ethernet work.
+u-boot loads ucode FLASH. The location for ucode:
+NOR Flash: 0xfe000000
+NAND Flash: 0x1f00000
+
+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 p1023rds.dts > p1023rds.dtb
+
+Likely, that .dts file will come from here;
+
+ linux-2.6/arch/powerpc/boot/dts/p1023rds.dts
+or
+ make p1023rds.dtb ARCH=powerpc
+in linux-2.6 directory.
+
+Booting Linux
+-------------
+Place a linux uImage in the TFTP disk area.
+
+ tftp 1000000 uImage
+ tftp 2000000 rootfs.ext2.gz.uboot
+ tftp c00000 p1023rds.dtb
+ bootm 1000000 2000000 c00000
