mpc83xx: New board support for SIMPC8313

This patch will create a new board, SIMPC8313, from Sheldon Instruments.  This
board boots from NAND devices and is configureable for either large or small
page devices.  The board supports non-soldered DDR2, one ethernet port, a
Marvell 88E1118 PHY, and PCI host support.  The board also has a FPGA connected
to the eLBC providing glue logic to a TMS320C67xx DSP.

+Sheldon Instruments SIMPC8313 Board
+-----------------------------------------
+
+1.	Board Switches and Jumpers
+
+	S2 is used to set CFG_RESET_SOURCE.
+
+	To boot the image in Large page NAND flash, use these DIP
+	switch settings for S2:
+
+	+----------+ ON
+	| * * **** |
+	|  * *     |
+	+----------+
+	  12345678
+
+	To boot the image in Small page NAND flash, use these DIP
+	switch settings for S2:
+
+	+----------+ ON
+	| *** **** |
+	|    *     |
+	+----------+
+	  12345678
+	(where the '*' indicates the position of the tab of the switch.)
+
+2.	Memory Map
+	The memory map looks like this:
+
+	0x0000_0000	0x1fff_ffff	DDR			512M
+	0x8000_0000	0x8fff_ffff	PCI MEM			256M
+	0x9000_0000	0x9fff_ffff	PCI_MMIO		256M
+	0xe000_0000	0xe00f_ffff	IMMR			1M
+	0xe200_0000	0xe20f_ffff	PCI IO			16M
+	0xe280_0000	0xe280_7fff	NAND FLASH (CS0)	32K
+	or
+	0xe280_0000	0xe281_ffff	NAND FLASH (CS0)	128K
+	0xff00_0000	0xff00_7fff	FPGA (CS1)		1M
+
+3.	Compilation
+
+	Assuming you're using BASH (or similar) as your shell:
+
+	export CROSS_COMPILE=your-cross-compiler-prefix-
+	make distclean
+	make SIMPC8313_LP_config
+	(or make SIMPC8313_SP_config, depending on the page size
+	of your NAND flash)
+	make
+
+4.	Downloading and Flashing Images
+
+4.1	Reflash U-boot Image using U-boot
+
+	=>run update_uboot
+
+	You may want to try
+	=>tftp $loadaddr $uboot
+	first, to make sure that the TFTP load will succeed before it
+	goes ahead and wipes out your current firmware.  And of course,
+	if the new u-boot doesn't boot, you can plug the board into
+	your PCI slot and with the supplied driver and sample app
+	you can reburn a working u-boot.
+
+4.2	Downloading and Booting Linux Kernel
+
+	Ensure that all networking-related environment variables are set
+	properly (including ipaddr, serverip, gatewayip (if needed),
+	netmask, ethaddr, eth1addr, fdtfile, and bootfile).
+
+	=>tftp $loadaddr uImage
+	=>nand write $loadaddr kernel $filesize
+	=>tftp $loadaddr $fdtfile
+	=>nand write $loadaddr 7e0000 1800
+
+	=>boot
+
+5	Notes
+
+	The console baudrate for SIMPC8313 is 115200bps.
