[U-Boot-Users] [PATCH 9/13] SPARC: Added LEON3 board GR-XC3S-1500.

28 Mar 2008

Hello Wolfgang,
This patch adds support for the LEON3 board:
 * GR-XC3S-1500 (Low cost Xilinx Spartan FPGA board)
Note that by board support I mean support for the
pre synthezied template design for the board. Supporting
any configuration is not possible but almost, due to the
Plug & Play system...
The FPGA can be programmed with the template design by:
 $ cd grlib/designs/BOARD
 $ make ise-prog-prom-ref
This patch is also available at 
ftp://ftp.gaisler.com/gaisler.com/u-boot/patches.
Best Regards,
Daniel Hellstrom
