+This patch allows passing in the gpio output mask used for GPIO0-7 on the
+PLX PCIe bridge. These GPIO's are used for PERST# on the downstream ports.
+
+Allowing the kernel to override the default configuration allows for keeping
+specific devices held in reset. One important use of this is to allow
+temporarily disabling devices that may request too many resources such as
+an unprogrammed i210 device.
