no this is the case only if you supposed that you use U-Boot as second
stage bootloader which is not the case for the PM9263, PM9261 and other
boards (9263ek too for norflash boot as example)

As already agree with Atmel dev, the bootstrap will have to init only what
it need to use which is not the case of the USB Host. U-Boot and other binary
will have to take care of it's own init.
