This patch series does:
1. max_bus_speed is used to set the device to gen2 speeds
2. on power there's no longer a conflict between the pseries call and other
architectures, because the overwrite is done via a ppc_md hook
3. radeon is using bus->max_bus_speed i
From: Lucas Kannebley Tavares
On pseries machines the detection for max_bus_speed should be done
through an OpenFirmware property. This patch adds a function to perform
this detection and a hook to perform dynamic adding of the function only for
pseries. This is done by overwriting the weak
pcibi
From: Lucas Kannebley Tavares
radeon currently uses a drm function to get the speed capabilities for
the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard
method of performing this detection and this patch changes it to use
the max_bus_speed attribute.
