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.
