- 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
