From daeb4c0c3bf2df72d0cd6e4330bad9e2e520552b Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 10 Mar 2012 11:39:33 +0000 Subject: ARM: PCI: get rid of pci_std_swizzle() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Most PCI implementations use the standard PCI swizzle function, which handles the well defined behaviour of PCI-to-PCI bridges which can be found on cards (eg, four port ethernet cards.) Rather than having almost every platform specify the standard swizzle function, make this the default when no swizzle function is supplied. Therefore, a swizzle function only needs to be provided when there is something exceptional which needs to be handled. This gets rid of the swizzle initializer from 47 files, and leaves us with just two platforms specifying a swizzle function: ARM Integrator and Chalice CATS.
