Thanks for the reply. And 2 more questions:

- there is no timeout control in the wait_until_xxx_ready() functions,
so when there no device plugged in u-boot will hang in these endless
loops.
- there is no root hub control, so we cannot use 'usb info' to get
device 0 root hub config info

do you have any plan to add these?

-Bryan
