STM32L4 host implementation

[friesendrywall]

Is there any documentation with an overview of porting an MCU as a host? Any idea how much time this would take?

I have a stm32f7 series host port on my personal projects using HAL_HCD. Probably a few subtle differences but may be a start

You would also need to enable to usb gpio, clocks and usb IRQ etc not shown here
