+-----------------------------------------
+
+1. Board Switches and Jumpers
+
+ S3 is used to set CFG_RESET_SOURCE.
+
+ To boot the image at 0xFE000000 in NOR flash, use these DIP
+ switche settings for S3 S4:
+
+ +------+ +------+
+ | | | **** |
+ | **** | | |
+ +------+ 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

+
+ CONFIG_MPC83xx MPC83xx family
+ CONFIG_MPC831x MPC831x specific
+ CONFIG_MPC8315 MPC8315 specific
+ CONFIG_MPC8315ERDB MPC8315ERDB board specific
+
+4. Compilation
+
+ Assuming you're using BASH (or similar) as your shell:
+
+ export CROSS_COMPILE=your-cross-compiler-prefix-
+ make distclean
+ make MPC8315ERDB_config
+ make all
+
+5. Downloading and Flashing Images
+
+5.1 Reflash U-boot Image using U-boot
+
+ tftp 40000 u-boot.bin
+ protect off all
+ erase fe000000 fe1fffff
+
+ cp.b 40000 fe000000 xxxx
+ protect on all
+
+ You have to supply the correct byte count with 'xxxx'
+ from the TFTP result log.
+
+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 MPC8315ERDB is 115200bps.

+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:
+
+ Address Range Device Size Port Size
+ (Bytes) (Bits)
+ =========================== ================= ======= =========
+ 0x0000_0000 0x0fff_ffff DDR 256M 64
+ 0x1000_0000 0x7fff_ffff Empty 1.75G -
+ 0x8000_0000 0x9fff_ffff PCI1 memory space 512M 32
+ 0xa000_0000 0xbfff_ffff PCI2 memory space 512M 32
+ 0xc200_0000 0xc2ff_ffff PCI1 I/O space 16M 32
+ 0xc300_0000 0xc3ff_ffff PCI2 I/O space 16M 32

+ 0xe280_0000 0xe47f_ffff NAND Flash 32M 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 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
