[Drivers] PCI base address

Hi !!
I am developing one linux drive for a nic which is memory mapped. The
problem I am facing is I get two different base memory addresses with two
methods.

My card's base memory address is stored at PCI_BASE_ADDRESS_0 which I will
map using ioremap() but problem is when I read
pcibios_read_config_dword() and
struct pci_dev *pdev=pci_find_slot()

/*************************************/
