Hi all,

             We are porting ecos for ixp425 evalution board, we are using
the grg 
             for the purpose ,
              now we are able to go up to plf_hardware_init

              we are strucking up at cyg_hal_plf_pci_init
 
in pci  it is using this address  are there any specific reasons

*IXP425_PCI_PCIMEMBASE = 0x48494A4B
*IXP425_PCI_AHBMEMBASE = 0x00010203

i am strucking at 

HAL_PCI_CFG_WRITE_UINT32(0, 0, CYG_PCI_CFG_BAR_1, 0x01000000);

can help me what is the reason or any pointers at this stage of porting
