+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.
