PCIe Hard IP BARs Configuration

Please,I try to communicate a FPGA Cyclone IV (EP) to a DSP C6678 (RC) using a PCIe Switch, I use the PCIe Hard IP and Avalon-MM , I need to configure the FPGA BARs in order to accept the TLPs sent by DSP, i ask if we have the possibility to access the FPGA BARs and configure them (code .vhdl or other thing)I try to communicate a FPGA Cyclone IV (EP) to a DSP C6678 (RC) using a PCIe Switch, I use the PCIe Hard IP and Avalon-MM , I need to configure the FPGA BARs in order to accept the TLPs sent by DSP, i ask if we have the possibility to access the FPGA BARs and configure them (code .vhdl or other thing).
