+Freescale MPC837xEMDS 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:

+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 MPC837XEMDS 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.
