Subject: arm: switch to GENERIC_PCI_IOMAP
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e5bfb72ce2ce558b5a5a46cc5694001f0479c7f2;p=mv-sheeva.git

arm: switch to GENERIC_PCI_IOMAP

arm copied pci_iomap from generic code, probably to avoid
pulling the rest of iomap.c in.  Since that's in
a separate file now, we can reuse the common implementation.
