From 43c34735524d5b1c9b9e5d63b49dd4c1b394bde4 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Thu, 4 Aug 2005 18:06:21 -0700 Subject: [PATCH] pci and yenta: pcibios_bus_to_resource In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).
