+Freescale MPC8313ERDB 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 Large 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
+	0xfa00_0000	0xfa00_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,
+	have an alternate means of programming the flash
available
+	if the new u-boot doesn't boot.
+
+4.2	Downloading and Booting Linux Kernel
+
+	TODO:
+
+5	Notes
+
+	The console baudrate for SIMPC8313 is 115200bps.
