+Freescale MPC8315ERDB Board
+-----------------------------------------
+
+1.	Board Switches and Jumpers
+
+	S3 is used to set CFG_RESET_SOURCE.
+
+	To boot the image at 0xFE000000 in NOR flash, use these DIP
+	switche settings for S3 S4:
+
+	+------+	+------+
+	|      |	| **** |
+	| **** |	|      |
+	+------+ 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
+	0xe030_0000	0xe03f_ffff	PCI IO		 1M
+	0xe060_0000	0xe060_7fff	NAND FLASH (CS1) 32K
+	0xfe00_0000	0xfe7f_ffff	NOR FLASH (CS0)	 8M
+
+3.	Definitions
+
+3.1	Explanation of NEW definitions in:
+
+	include/configs/MPC8315ERDB.h
+
+	CONFIG_MPC83xx		MPC83xx family
+	CONFIG_MPC831x		MPC831x specific
+	CONFIG_MPC8315		MPC8315 specific
+	CONFIG_MPC8315ERDB	MPC8315ERDB board specific
+
+4.	Compilation
+
+	Assuming you're using BASH (or similar) as your shell:
+
+	export CROSS_COMPILE=your-cross-compiler-prefix-
+	make distclean
+	make MPC8315ERDB_config
+	make all
+
+5.	Downloading and Flashing Images
+
+5.1	Reflash U-boot Image using U-boot
+
+	tftp 40000 u-boot.bin
+	protect off all
+	erase fe000000 fe1fffff
+
+	cp.b 40000 fe000000 xxxx
+	protect on all
+
+	You have to supply the correct byte count with 'xxxx'
+	from the TFTP result log.
+
+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 MPC8315ERDB is 115200bps.
