rtems source builder on flexible hardware (FPGA)

Hello Sebastian and Ric,
I think it would be good to think about a unification of these BSPS.
In the Virtex BSB as I understood some information are given by the configure process while others are taken from the xparameters.h file which is generated by the Xilinx tools.
The xparameter.h approach is Xilinx specific and also the syntax of the defines has changed throughout the different versions of Xilinx ISE/XPS
We use for now the virtex bsp together with RSb and environment variables (see other mailing list email)

If I recall correctly, the virtex BSP expects the architecture of a particular Virtex 4 evaluation board and to have certain firmware loaded onto the FPGA fabric.  I wrote the virtex4 and virtex5 BSPs to be generic.
