4 Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls
6 the USB host controller init calls take a long time, mostly due to a
7 "minimally 100 msec" delay *per port* during initialization.
8 These are prime candidates for going in parallel to everything else.
10 The USB device ordering is not affected by this due to the
11 serialized-within-eachother property of async initcalls.
