From 5160d3f782a5e0cdb3bdaa8a891a1fb9d9ab83ec Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 20 Apr 2009 18:47:21 +0900 Subject: sh: pci: Consolidate bus<->resource mapping in pci-lib. Now that the io and mem offsets are tracked accordingly, the pci-new version of the bus<->resource mappers can be used generically. This moves them in to pci-lib.
