e6b66f1092 stm32/usb: Initialise cdc variable to prevent compiler warnings.
Some compilers cannot deduce that cdc will always be written before being
used.

47ecbbbecb stm32/usb: Add ability to have 2x VCP interfaces on the one USB device.
This patch adds the configuration MICROPY_HW_USB_ENABLE_CDC2 which enables
a new USB device configuration at runtime: VCP+VCP+MSC.  It will give two
independent VCP interfaces available via pyb.USB_VCP(0) and pyb.USB_VCP(1).
The first one is the usual one and has the REPL on it.  The second one is
available for general use.

This configuration is disabled by default because if the mode is not used
then it takes up about 2200 bytes of RAM.  Also, F4 MCUs can't support this
mode on their USB FS peripheral (eg PYBv1.x) because they don't have enough
endpoints.  The USB HS peripheral of an F4 supports it, as well as both the
USB FS and USB HS peripherals of F7 MCUs.

1f1623d3b7 stm32/usbdev: Be honest about data not being written to HID endpoint.
USB_HID.send() should now return 0 if it could not send the report to the
host.

5c320bd0b0 stm32: Introduce MICROPY_HW_ENABLE_USB and clean up USB config.
This patch allows to completely compile-out support for USB, and no-USB is
now the default.  If a board wants to enable USB it should define:

    #define MICROPY_HW_ENABLE_USB (1)

And then one or more of the following to select the USB PHY:

    #define MICROPY_HW_USB_FS (1)
    #define MICROPY_HW_USB_HS (1)
    #define MICROPY_HW_USB_HS_IN_FS (1)

8e1cb58a23 stm32/usbdev: Fix USBD setup request handler to use correct recipient.
Prior to this patch the USBD driver did not handle the recipient correctly
for setup requests.  It was not interpreting the req->wIndex field in the
right way: in some cases this field indicates the endpoint number but the
code was assuming it always indicated the interface number.

This patch fixes this.  The only noticeable change is to the MSC
interface, which should now correctly respond to the USB_REQ_CLEAR_FEATURE
request and hence unmount properly from the host when requested.

db702ba722 stm32/usbdev: Add support for high-speed USB device mode.
This patch adds support in the USBD configuration and CDC-MSC-HID class for
high-speed USB mode.  To enable it the board configuration must define
USE_USB_HS, and either not define USE_USB_HS_IN_FS, or be an STM32F723 or
STM32F733 MCU which have a built-in HS PHY.  High-speed mode is then
selected dynamically by passing "high_speed=True" to the pyb.usb_mode()
function, otherwise it defaults to full-speed mode.

This patch has been tested on an STM32F733.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
