[U-Boot] [PATCH] ehci-hcd: Allow cleanups to happen on an EHCI timeout.

[Joel A Fernandes <agnel.joel@gmail.com>]

With this, the EHCI seems to "recover" from a timeout. This is particularly
observable if you were to ping the wrong IP Address and then ping the correct
one or if there was a temporary failure during tftp sessions.

All it takes is one timeout to disable it. If you have a noisy network (lot
of traffic), even if the traffic is not for the board, the timeouts don't occur.

Robert, Could you see if this patch solves the issue you're seeing without
increasing the timeout?
Simon, Could this be a fix for a similar issue you were seeing with asix?
