Subject: [patch 2/5] pci and yenta: pcibios_bus_to_resource
Date: Thu, 4 Aug 2005 18:06:21 -0700 [thread overview]
Message-ID: <20050805010621.GC19625@kroah.com> (raw)
In-Reply-To: <20050805010533.GA19625@kroah.com>
[-- Attachment #1: pci-pcibios_bus_to_resource.patch --]
[-- Type: text/plain, Size: 8651 bytes --]
From: Dominik Brodowski <linux@dominikbrodowski.net>
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() ?).
