+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.

-The port was tested on Wind River System Sbc8560 board <www.windriver.com>.
-U-Boot was installed on the flash memory of the CPU card (no the SODIMM).
-
-NOTE: Please configure uboot compile to the proper PCI frequency and
-setup the appropriate DIP switch settings.
-
-SBC8560 board:
-
-Make sure boards switches are set to their appropriate conditions.
-Refer to the Engineering Reference Guide ERG-00300-002. Of particular
-importance are: 1)Tthe settings for JP4 (JP4 1-3 and 2-4), which
-select the on-board FLASH device (Intel 28F128Jx); 2) The settings
-for the Clock SW9 (33 MHz or 66 MHz).
-
-	Note:	SW9 Settings: 66 MHz
-		4:1 ratio CCB clocks:SYSCLK
-		3:1 ration e500 Core:CCB
-		pos1 - on, pos2 - on, pos3 - off, pos4 - on, pos5 - off, pos6 - on
-	Note:	SW9 Settings: 33 MHz
-		8:1 ratio CCB clocks:SYSCLK
-		3:1 ration e500 Core:CCB
-		pos1 - on, pos2 - on, pos3 - on, pos4 - off, pos5 - off, pos6 - on

-
-Flashing the FLASH device with the "Wind River ICE":
-
-1) Properly connect and configure the Wind River ICE to the
-   target JTAG port. This includes running the SBC8560 register script.
-   Make sure target memory can be read and written.
-
-2) Build the u-boot image:
-	make distclean
-	make SBC8560_66_config or SBC8560_33_config
-	make CROSS_COMPILE=.../ELDK3.0/ppc_8xx-/ all
-
-   Note: reference is made to the ELDK3.0 compiler but any 85xx cross-compiler
-	 should suffice.
-
-3) Convert the uboot (.elf) file to a uboot.bin file (using visionClick converter).
-   The bin file should be converted from fffc0000 to ffffffff
-
-4) Setup the Flash Utility (tools menu) for:
-
-   Determine the clock speed of the PCI bus and set SW9 accordingly
-	Note: the speed of the PCI bus defaults to the slowest PCI card
-   PlayBack the "default" register file for the SBC8560
-   Select the uboot.bin file with zero bias
-   Select the initialize Target prior to programming
-   Select the V28F640Jx (8192 x 8) 1 device FLASH Algorithm
-   Select the erase base address from FFFC0000 to FFFFFFFF
-   Select the start address from 0 with size of 4000
-
-5) Erase and Program
