OK, with the addition of an appropriate pin_mux_usb() function to
harmony.c, this works now. So, please consider the series,
Tested-by: Stephen Warren <swarren@wwwdotorg.org>
Note that I did see the following:
Tegra20 (Harmony) # usb start
(Re)start USB...
USB: Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... Register 10011 NbrPorts 1
USB EHCI 1.00
scanning bus for devices... 5 USB Device(s) found
scanning bus for storage devices... Device NOT ready
Request Sense returned 02 3A 00
2 Storage Device(s) found
scanning bus for ethernet devices... 1 Ethernet Device(s) found
However, both "usb tree" and then "ext2ls" on the USB device succeeded
without issue, so I think that's tested well enough. I even booted a
kernel from the USB device, and the kernel was able to use the USB
device for the root filesystem, so U-Boot hadn't broken it in any way:-)
