Freescale MPC837xE-RDB Board
-----------------------------------------

1.	Board Description

	The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
	MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.

	The MPC837xE-RDB's have the following common features:

	A) 256-MBytes on-board DDR2 unbuffered SDRAM
	B) 8-Mbytes NOR Flash
	C) 32-MBytes NAND Flash
	D) 1 Secure Digital High Speed Card (SDHC) Interface
	E) 1 Gigabit Ethernet
	F) 5-port Ethernet switch (Vitesse 7385)
	G) 1 32-bit, 3.3 V, PCI slot
	H) 1 32-bit, 3.3 V, Mini-PCI slot
	I) 4-port USB 2.0 Hub
	J) 1-port OTG USB
	K) 2 serial ports (top main console)
	L) on board Oscillator: 66M

	The MPC837xE-RDB's have the following differences:

			    MPC8377E-RDB    MPC8378E-RDB    MPC8379E-RDB
	SATA controllers	2		0		4
	PCI-Express (mini)	2		2		0
	SGMII Ports		0		2		0


2.	Memory Map

2.1.	The memory map should look pretty much like this:

	Address Range			Device			Size		Port Size
								(Bytes)		(Bits)
	===========================	=================	=======		=========
	0x0000_0000	0x0fff_ffff	DDR			256M		64
	0x1000_0000	0x7fff_ffff	Empty			1.75G		-
	0x8000_0000	0x8fff_ffff	PCI MEM prefetch	256M		32
	0x9000_0000	0x9fff_ffff	PCI MEM non-prefetch	256M		32
	0xe030_0000	0xe03f_ffff	PCI I/O space		1M		32
	0xe000_0000	0xe00f_ffff	Int Mem Reg Space	1M		-
	0xe060_0000	0xe060_7fff	NAND Flash		32K		8
	0xfe00_0000	0xfe7f_ffff	NOR Flash on CS0	8M		16


3. Definitions

3.1 Explanation of NEW definitions in:

	include/configs/MPC837XERDB.h

    CONFIG_MPC83XX	    MPC83xx family for both MPC8349 and MPC8360
    CONFIG_MPC837X	    MPC837x specific
    CONFIG_MPC837XERDB	    MPC837xE-RDB board specific


4. Compilation

	Assuming you're using BASH shell:

		export CROSS_COMPILE=your-cross-compile-prefix
		cd u-boot
		make distclean
		make MPC837XERDB_config
		make


5. Downloading and Flashing Images

5.0 Download over serial line using Kermit:

	loadb $loadaddr
	[Drop to kermit:
	    ^\c
	    send <u-boot-bin-image>
	    c
	]


	Or via tftp:

	tftp $loadaddr u-boot.bin

5.1 Reflash U-boot Image using U-boot

	tftp $loadaddr u-boot.bin
	protect off fe000000 fe0fffff
	erase fe000000 fe0fffff
	cp.b $loadaddr fe000000 $filesize


6. Additional Notes:
	1) The console is connected to the top RS-232 connector and the
	   baudrate for MPC837XE-RDB is 115200bps.
