I am using MPC8378 processor in legacy design. MPC8378 PCI bus is not used in the design and all PCI Address lines were kept open in the design. We have initialized the RCWHR[PCIHOST] = 1 & RCWHR[PCIARB] = 1 in software. We haven't initialized the PCIACR[PM] = 1 or PCI_GCR[BBR] = 1 in software. Now we don't have opportunity to update the software. Is there any impact if we keep default value to PCIACR[PM] & PCI_GCR[BBR] in software?
Thanks for your support.
