-The port was tested on Wind River System Sbc8560 board <www.windriver.com>.
-U-Boot was installed on the flash memory of the CPU card (no the SODIMM).
-
-NOTE: Please configure uboot compile to the proper PCI frequency and
-setup the appropriate DIP switch settings.
-
-SBC8560 board:
-
-Make sure boards switches are set to their appropriate conditions.
-Refer to the Engineering Reference Guide ERG-00300-002. Of particular
-importance are: 1)Tthe settings for JP4 (JP4 1-3 and 2-4), which
-select the on-board FLASH device (Intel 28F128Jx); 2) The settings
-for the Clock SW9 (33 MHz or 66 MHz).
-
-	Note:	SW9 Settings: 66 MHz
-		4:1 ratio CCB clocks:SYSCLK
-		3:1 ration e500 Core:CCB
-		pos1 - on, pos2 - on, pos3 - off, pos4 - on, pos5 - off, pos6 - on
-	Note:	SW9 Settings: 33 MHz
-		8:1 ratio CCB clocks:SYSCLK
-		3:1 ration e500 Core:CCB
-		pos1 - on, pos2 - on, pos3 - on, pos4 - off, pos5 - off, pos6 - on

-Flashing the FLASH device with the "Wind River ICE":
-
-1) Properly connect and configure the Wind River ICE to the
-   target JTAG port. This includes running the SBC8560 register script.
-   Make sure target memory can be read and written.
-
-2) Build the u-boot image:
-	make distclean
-	make SBC8560_66_config or SBC8560_33_config
-	make CROSS_COMPILE=.../ELDK3.0/ppc_8xx-/ all
-
-   Note: reference is made to the ELDK3.0 compiler but any 85xx cross-compiler
-	 should suffice.
-
-3) Convert the uboot (.elf) file to a uboot.bin file (using visionClick converter).
-   The bin file should be converted from fffc0000 to ffffffff
-
-4) Setup the Flash Utility (tools menu) for:
-
-   Determine the clock speed of the PCI bus and set SW9 accordingly
-	Note: the speed of the PCI bus defaults to the slowest PCI card
-   PlayBack the "default" register file for the SBC8560
-   Select the uboot.bin file with zero bias
-   Select the initialize Target prior to programming
-   Select the V28F640Jx (8192 x 8) 1 device FLASH Algorithm
-   Select the erase base address from FFFC0000 to FFFFFFFF
-   Select the start address from 0 with size of 4000
-
-5) Erase and Program
