Subject: [patch 02/16] alpha: use generic pci_enable_resources()
Date: Tue, 04 Mar 2008 11:56:48 -0700 [thread overview]
Message-ID: <20080304185820.125200297@ldl.fc.hp.com> (raw)
In-Reply-To: 20080304185646.864917286@ldl.fc.hp.com
Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- skips resources unless requested in "mask"
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"
