handling 16 bit addresses

[Medeiros Edward M NPRI <MedeirosEM@xxxxxxxxxxxxxxxxx>]

Hello,

 

I have a PCI driver that returns a 16 bit I/O space address when I call "pci_resource_start()".   My question is how do I use this 16 bit address??

When I pass it to "ioremap()" it gets mapped to 0x00000000 which is incorrect.  I think I am missing a step here.

 

Thank you.
