This patch adds the PCI support (as EXPERIMENTAL) this has been also tested on XLINX XC2V3000 FF1152AMT0221 D1215994A VIRTEX FPGA board. To support the PCI bus the main part has been reworked and both the platform and the PCI specific parts have been moved into different files.

points to two data buffer pointers whereas in CHAINED mode they
