Hello Wolfgang,
This patch adds support for the LEON3 board: * GR-CPCI-AX2000 (AX system with switchable AX FPGA)
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
