Hi,
I was under the wrong impression earlier that CONFIG_USB_DWC3 is needed for USB HOST operation, but it seems it is not so. Just CONFIG_XHCI_DWC3 and CONFIG_XHCI_OMAP are sufficient to get USB host working.
So the real problem was that some offending commits didn't define enable_usb_clocks() and board_usb_init for the XHCI host only case.
Patches 1 and 2 fix this and get USB host working on am57xx and am43xx. NOTE: my am437xx is broken so I've only tested this on am57xx-evm.
The remaining 2 patches attempt to fix USB3 PHY to get Super-Speed host functional but I haven't yet got Super-Speed working in u-boot. Patch 4 does fix an issue with Kernel failing to detect Super-Speed devices.
cheers, -roger
