+Subject: [PATCH] usb: xhci: Disable the XHCI 5 second timeout
+
+If the VL805 EEPROM has not been programmed then boot will hang for five
+seconds. The timeout seems to be arbitrary and is an unecessary
+delay on the first boot. Remove the timeout.
+
+This is common code and probably can't be upstreamed unless the timeout
+can be configurable somehow or perhaps the XHCI driver can be skipped
+on the first boot.
