Other Parts Discussed in Thread: PCI1520

1.My project alternatives is PPC440EP+PCI1520+CF Card,but  I don't kown  how to initialize  PCI1520.

2.The  principle  of  mapping the address to CPU and CF card,only by this can I operate the CF  Crad.

3.The software plan  is UBOOT+Linux, I wonder  if   I  ought to configure  CF Card  through  PCI1520.Because there are to many registers  in PCI1520.
