mpc83xx: add support for the MPC8323E RDB

MPC8323E based board with 64MB fixed SDRAM, 16MB flash,
five 10/100 ethernet ports connected via an ICPlus IP175C
switch, one PCI slot, and serial.  Features not supported
in this patch are SD card interface, 2 USB ports, and the
two phone ports.

+Freescale MPC8323ERDB Board
+-----------------------------------------
+
+1.	Memory Map
+	The memory map looks like this:
+
+	0x0000_0000	0x03ff_ffff	DDR		 64M
+	0x8000_0000	0x8fff_ffff	PCI MEM		 256M
+	0x9000_0000	0x9fff_ffff	PCI_MMIO	 256M
+	0xe000_0000	0xe00f_ffff	IMMR		 1M
+	0xd000_0000	0xd3ff_ffff	PCI IO		 64M
+	0xfe00_0000	0xfeff_ffff	NOR FLASH (CS0)	 16M
+
+2.	Compilation
+
+	Assuming you're using BASH (or similar) as your shell:
+
+	export CROSS_COMPILE=your-cross-compiler-prefix-
+	make distclean
+	make MPC8323ERDB_config
+	make
+
+3.	Downloading and Flashing Images
+
+3.1	Reflash U-boot Image using U-boot
+
+	N.b, have an alternate means of programming
+	the flash available if the new u-boot doesn't boot.
+
+	First try a:
+
+	tftpboot $loadaddr $uboot
+
+	to make sure that the TFTP load will succeed before
+	an erase goes ahead and wipes out your current firmware.
+	Then do a:
+
+	run tftpflash
+
+	which is a shorter version of the manual sequence:
+
+	tftp $loadaddr u-boot.bin
+	protect off fe000000 +$filesize
+	erase fe000000 +$filesize
+	cp.b $loadaddr fe000000 $filesize
+
+	To keep your old u-boot's environment variables, do a:
+
+	saveenv
+
+	prior to resetting the board.
+
+3.2	Downloading and Booting Linux Kernel
+
+	Ensure that all networking-related environment variables are set
+	properly (including ipaddr, serverip, gatewayip (if needed),
+	netmask, ethaddr, eth1addr, rootpath (if using NFS root),
+	fdtfile, and bootfile).
+
+	Then, do one of the following, depending on whether you
+	want an NFS root or a ramdisk root:
+
+	run nfsboot
+
+	or
+
+	run ramboot
+
+4	Notes
+
+	The console baudrate for MPC8323ERDB is 115200bps.
