Damien George 1e4849557d esp32/usb: Further improve speed of USB CDC output.
Following on from ba940250a5, the change here
makes output about 15 times faster (now up to about 550 kbytes/sec).

tinyusb_cdcacm_write_queue will return the number of bytes written, so
there's no need to use tud_cdc_n_write_available.

Damien George 549448e8bb esp32: Enable optimisations and move code to iRAM to boost performance.
This commit enables some significant optimisations for esp32:
- move the VM to iRAM
- move hot parts of the runtime to iRAM (map lookup, load global/name,
  mp_obj_get_type)
- enable MICROPY_OPT_LOAD_ATTR_FAST_PATH
- enable MICROPY_OPT_MAP_LOOKUP_CACHE
- disable assertions
- change from -Os to -O2 for compilation

It's hard to measure performance on esp32 due to external flash and
hardware caching.  But this set of changes improves performance compared to
master by (on a TinyPICO with the GENERIC build, using IDF 4.2.2, running
at 160MHz):

Five tests have more than 3x speed up (200%+).

The performance of the tests bm_fft, bm_pidigits and misc_aes now scale
with CPU frequency (eg changing frequency to 240MHz boosts the performance
of these by 50%), which means they are no longer influenced by timing of
external flash access.  (The viper_call* tests did previously scale with
CPU frequency, and they still do.)

Turning off assertions reduces code size by about 80k, and going from -Os
to -O2 costs about 100k, so the net change in code size (for the GENERIC
board) is about +20k.

If a board wants to enable assertions, or use -Os instead of -O2, that's
still possible by overriding the sdkconfig parameters.

Damien George f046b50ca5 esp32/main: Add option for a board to hook code into startup sequence.
To do this the board must define MICROPY_BOARD_STARTUP, set
MICROPY_SOURCE_BOARD then define the new start-up code.

For example, in mpconfigboard.h:

    #define MICROPY_BOARD_STARTUP board_startup
    void board_startup(void);

in mpconfigboard.cmake:

    set(MICROPY_SOURCE_BOARD
        ${MICROPY_BOARD_DIR}/board.c
    )

and in a new board.c file in the board directory:

    #include "py/mpconfig.h"

    void board_startup(void) {
        boardctrl_startup();
        // extra custom startup
    }

This follows stm32's boardctrl facilities.

leo chung 4fdf795efa esp32/mpthreadport: Fix TCB cleanup function so thread_mutex is ready.
Because vPortCleanUpTCB is called by the FreeRTOS idle task, and it checks
thread, but didn't check the thread_mutex.

And if thread is not NULL, but thread_mutex not ready then it will crash
with an error when calling mp_thread_mutex_lock(&thread_mutex, 1).

As suggested by @dpgeorge, move the thread = &thread_entry0 line to the end
of mp_thread_init().

IhorNehrutsa 52636fa692 esp32/machine_pwm: Add support for all PWM timers and channels.
This commit allows using all the available PWM timers (up to 8) and
channels (up to 16), without affecting the PWM API.

If a new frequency is set, first it checks if another timer is using the
same frequency.  If yes, then it uses this timer, otherwise, it creates a
new one.  If all timers are used, the user should set an already used
frequency, or de-init a channel.

This work is based on #6276 and #3608.

Patrick Van Oosterwijck a66bd7a489 esp32/boards: Add GENERIC_C3_USB board with USB serial/JTAG support.
Add a new board type for ESP32-C3 revision 3 and up that implement the USB
serial/JTAG port on pin 18 and 19.  This variant uses the USB serial for
programming and console, leaving the UART free.

- Pins 18 and 19 are correctly reserved for this variant.  Also pins 14-17
  are reserved for flash for any ESP32-C3 so they can't be reconfigured
  anymore to crash the system.
- Added usb_serial_jtag.c and .h to implement this interface.
- Interface was tested to work correctly together with webrepl.
- Interface was tested to work correctly when sending and receiving
  large files with ampy.
- Disconnecting terminal or USB will not hang the system when it's
  trying to print.

Will Sowerbutts a3675294ae esp32/machine_uart: Add flow kw-arg to enable hardware flow control.
This enables optional support for the hardware UART to use the RTS and/or
CTS pins for flow control.

The new "flow" constructor keyword specifies a bitmask of RTS and/or CTS.
This matches the interface used by machine.UART on stm32 and rp2.

Previously on ESP32 it was possible to specify which pins to use for the
RTS and CTS signals, but hardware flow control was never functional: CTS
was not checked before transmitting bytes, and RTS was always driven high
(signalling no buffer space available).  With this patch, CTS and RTS both
operate as expected.

This also includes an update to the machine.UART documentation.
