I've tested USB support on AM62x SK EVM for this whole series based on a
public TI integration branch:

https://git.ti.com/cgit/ti-u-boot/ti-u-boot/log/?h=ti-u-boot-2023.04-next

I did not test DFU, however with some small config changes I could test
fastboot support using:

=> fastboot usb 0

Then from host:
$ fastboot devices
$ fastboot flash <partition_label> <image_file>
