mpc83xx: New board support for SIMPC8313

Browse Source 
This patch will create a new board, SIMPC8313, from Sheldon Instruments.  This
board boots from NAND devices and is configureable for either large or small
page devices.  The board supports non-soldered DDR2, one ethernet port, a
Marvell 88E1118 PHY, and PCI host support.  The board also has a FPGA connected
to the eLBC providing glue logic to a TMS320C67xx DSP.

Sheldon Instruments SIMPC8313 Board
-----------------------------------------
1. Board Switches and Jumpers
S2 is used to set CFG_RESET_SOURCE.
To boot the image in Large page NAND flash, use these DIP
switch settings for S2:
+----------+ ON
| * * **** |
| * * |
+----------+
12345678
To boot the image in Small page NAND flash, use these DIP
switch settings for S2:
+----------+ ON
| *** **** |
| * |
+----------+
12345678
(where the '*' indicates the position of the tab of the switch.)
2. Memory Map
The memory map looks like this:
0x0000_0000 0x1fff_ffff DDR 512M
0x8000_0000 0x8fff_ffff PCI MEM 256M
0x9000_0000 0x9fff_ffff PCI_MMIO 256M
0xe000_0000 0xe00f_ffff IMMR 1M
0xe200_0000 0xe20f_ffff PCI IO 16M
0xe280_0000 0xe280_7fff NAND FLASH (CS0) 32K
or
0xe280_0000 0xe281_ffff NAND FLASH (CS0) 128K
0xff00_0000 0xff00_7fff FPGA (CS1) 1M
3. Compilation
Assuming you're using BASH (or similar) as your shell:
export CROSS_COMPILE=your-cross-compiler-prefix-
make distclean
make SIMPC8313_LP_config
(or make SIMPC8313_SP_config, depending on the page size
of your NAND flash)
make
4. Downloading and Flashing Images
4.1 Reflash U-boot Image using U-boot
=>run update_uboot
You may want to try
=>tftp $loadaddr $uboot
first, to make sure that the TFTP load will succeed before it
goes ahead and wipes out your current firmware. And of course,
if the new u-boot doesn't boot, you can plug the board into
your PCI slot and with the supplied driver and sample app
you can reburn a working u-boot.
4.2 Downloading and Booting Linux Kernel
Ensure that all networking-related environment variables are set
properly (including ipaddr, serverip, gatewayip (if needed),
netmask, ethaddr, eth1addr, fdtfile, and bootfile).
=>tftp $loadaddr uImage
=>nand write $loadaddr kernel $filesize
=>tftp $loadaddr $fdtfile
=>nand write $loadaddr 7e0000 1800
=>boot
5 Notes
The console baudrate for SIMPC8313 is 115200bps.
