4 1.	Board Description
5 
6 	The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
7 	MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.
8 
9 	The MPC837xE-RDB's have the following common features:
10 
11 	A) 256-MBytes on-board DDR2 unbuffered SDRAM
12 	B) 8-Mbytes NOR Flash
13 	C) 32-MBytes NAND Flash
14 	D) 1 Secure Digital High Speed Card (SDHC) Interface
15 	E) 1 Gigabit Ethernet
16 	F) 5-port Ethernet switch (Vitesse 7385)
17 	G) 1 32-bit, 3.3 V, PCI slot
18 	H) 1 32-bit, 3.3 V, Mini-PCI slot
19 	I) 4-port USB 2.0 Hub
20 	J) 1-port OTG USB
21 	K) 2 serial ports (top main console)
22 	L) on board Oscillator: 66M
23 
24 	The MPC837xE-RDB's have the following differences:
25 
26 			    MPC8377E-RDB    MPC8378E-RDB    MPC8379E-RDB
27 	SATA controllers	2		0		4
28 	PCI-Express (mini)	2		2		0
29 	SGMII Ports		0		2		0

32 2.	Memory Map
33 
34 2.1.	The memory map should look pretty much like this:
35 
36 	Address Range			Device			Size		Port Size
37 								(Bytes)		(Bits)
38 	===========================	=================	=======		=========
39 	0x0000_0000	0x0fff_ffff	DDR			256M		64
40 	0x1000_0000	0x7fff_ffff	Empty			1.75G		-
41 	0x8000_0000	0x8fff_ffff	PCI MEM prefetch	256M		32
42 	0x9000_0000	0x9fff_ffff	PCI MEM non-prefetch	256M		32
43 	0xe030_0000	0xe03f_ffff	PCI I/O space		1M		32
44 	0xe000_0000	0xe00f_ffff	Int Mem Reg Space	1M		-
45 	0xe060_0000	0xe060_7fff	NAND Flash		32K		8
46 	0xfe00_0000	0xfe7f_ffff	NOR Flash on CS0	8M		16

71 5. Downloading and Flashing Images
72 
73 5.0 Download over serial line using Kermit:
74 
75 	loadb $loadaddr
76 	[Drop to kermit:
77 	    ^\c
78 	    send <u-boot-bin-image>
79 	    c
80 	]
