* Patch by Michael Bendzick, 30 Aug 2004:
- Improve platform.S code for omap1510inn that detects whether code is running from SDRAM or not. Patch allows SDRAM to be configured if code is running out of SRAM at 0x20000000. * Patch by Frederick Klatt, 30 Aug 2004: Add support for the Wind River SBC8540/SBC8560 boards

+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. Further, it seems the ppc_8xx compiler is
+ required for the 85xx (no 85xx designated compiler in ELDK3.0)
+
+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:
+
+ Do a "dc clr" [visionClick] to load the default register settings
+ 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
