+Freescale MPC8313ERDB Board
+-----------------------------------------
+
+1.	Board Switches and Jumpers
+
+	SW3 is used to set CFG_RESET_SOURCE.
+
+	To boot the image at 0xFE000000 in NOR flash, use these DIP
+	switche settings for SW3 SW4:
+
+	+------+	+------+
+	|      |	| **** |
+	| **** |	|      |
+	+------+ ON	+------+ ON
+	  4321		  4321
+	(where the '*' indicates the position of the tab of the switch.)
+
+2.	Memory Map
+	The memory map looks like this:
+
+	0x0000_0000	0x07ff_ffff	DDR		 128M
+	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 (CS1) 32K
+	0xf000_0000	0xf001_ffff	VSC7385 (CS2)	 128K
+	0xfa00_0000	0xfa00_7fff	Board Status/	 32K
+					LED Control (CS3)
+	0xfe00_0000	0xfe7f_ffff	NOR FLASH (CS0)	 8M
+
+3.	Definitions
+
+3.1	Explanation of NEW definitions in:
+
+	include/configs/MPC8313ERDB.h
+
+	CONFIG_MPC83xx		MPC83xx family
+	CONFIG_MPC831x		MPC831x specific
+	CONFIG_MPC8313ERDB	MPC8313ERDB board specific
+
+4.	Compilation
+
+	Assuming you're using BASH (or similar) as your shell:
+
+	export CROSS_COMPILE=your-cross-compiler-prefix-
+	make distclean
+	make MPC8313ERDB_33_config
+	(or make MPC8313ERDB_66_config, depending on the speed of
+	 the oscillator on your board)
+	make
+
+5.	Downloading and Flashing Images
+
+5.1	Reflash U-boot Image using U-boot
+
+	=>run tftpflash
+
+	You may want to try
+	=>tftpboot $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,
+	have an alternate means of programming the flash available
+	if the new u-boot doesn't boot.
+
+5.2	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
+
+6	Notes
+
+	Booting from NAND flash is not yet supported.
+	The console baudrate for MPC8313ERDB is 115200bps.
