Hi Peng, Ye, Peter,
Currently there in no any usb host/gadget support in the mainline U-boot, and seems that no one has posted anything yet to the mailing list (at least I haven't found anything related to this in the ML archives).
I've spent some time testing (usb host, ums etc.) the one in the downstream NXP U-boot (I'm still not sure where is the official NXP downstream rep, because there are no any updates in [1] for the last two years, so I looked into [2], [3]), and just curious if there any plans to get it upstreamed in the near future?
Thanks and looking forward to your reply!
