I've got usb working with my patches here:

https://patchwork.ozlabs.org/project/uboot/list/?series=97658

That means we have all the bootmodes for am335x working as shown in this

http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User%27s_Guide#Compiling_MLO_and_u-boot

The only problem I see is with using environment in falcon boot. Can we
live with that?

Thanks,
