Dear Stephen Warren,

A known hardware issue of USB1 port where bit 1 (connect status change) of PORTSC register will be set after issuing Port Reset (like "usb reset" in u-boot command line). This will be treated as an error and stops later device enumeration.
Therefore we clear that bit after Port Reset in order to proceed later device enumeration.

Ok, it's icky nvidia stuff :-)
Will you apply it? I'm good with the current shape.
This will be applied to u-boot-tegra/next as soon as I'm done validating Allen's SPL changes.
Good, I'm sure I'm leaving it in good hands :)
Thanks Tom!
Tom
