It makes no sense to do PCIe WA window setup in the individual board support files while the decision whether or not to use the PCIe WA access method is made in a different place, in the PCIe support code. This patch moves the configuration of a PCIe WA window from the individual Orion board support files to the central Orion PCIe support code.
