+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)

+4. Compilation
+
+       Assuming you're using BASH shell:
+
+               export CROSS_COMPILE=your-cross-compile-prefix
+               cd u-boot
