[U-Boot] [PATCH] mpc83xx: New board support SIMPC8313

Ron Madrid
2008-11-05T00:37:45Z

This patch will create a new board, SIMPC8313, from Sheldon Instruments. This
board boots from NAND devices and is configurable for either a large page or
small page device.

+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
+
+ TODO:
+
+5 Notes
+
+ The console baudrate for SIMPC8313 is 115200bps.
