This patch series breaks USB support on the A10 Cubieboard, with
Cubieboard_defconfig. I'm booting off an SD card, with a USB storage
device plugged into the lower of the two USB ports.
With aa29b11b3f ("Add a sunxi specific function for setting
squelch-detect") and older versions, everything is OK and u-boot can see
the USB device:

With dd3228170a ("Switch to use generic-phy"), I get:

And with f5871a66fd ("Drop legacy usb_phy.c") and later versions
including current master, I get:

Note the 0.00 revision numbers in the EHCI/OHCI lowlevel init output
there. Any ideas about what might have gone wrong?
Let me know if you need any more information...
