4 | Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls | ||
5 | |||
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. | ||
9 | |||
10 | The USB device ordering is not affected by this due to the | ||
11 | serialized-within-eachother property of async initcalls. | ||
