The following patches add support for USB mass storage and USB dfu bootmodes on am654x-idk.
Because of space constrains and the size of the USB stack, there are two different usbmsc and usbdfu defconfigs for building R5 SPL. Fitting both of these into one defconfig requires some changes in the USB subsystem which is a longer term effort
