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