Thorsten von Eicken d28dbcd6c7 esp32: Make machine.soft_reset() work in main.py and reset_cause().
This commit fixes two issues on the esp32:
- it enables machine.soft_reset() to be called in main.py;
- it enables machine.reset_cause() to correctly identify a soft reset.

The former is useful in that it enables soft resets in applications that
are started at boot time.  The support is patterned after the stm32 port.

Thorsten von Eicken c10d431819 esp32: Add basic support for Non-Volatile-Storage in esp32 module.
This commit implements basic NVS support for the esp32.  It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace.  The initial support provided is only for signed 32-bit integers
and binary blobs.  It's easy (albeit a bit tedious) to add support for
more types.

Damien George 9b90882146 esp32: Add support to build using IDF with cmake.
This commit adds support for building the esp32 port with cmake, and in
particular it builds MicroPython as a component within the ESP-IDF.  Using
cmake and the ESP-IDF build infrastructure makes it much easier to maintain
the port, especially with the various new ESP32 MCUs and their required
toolchains.

Damien George ad4656b861 all: Rename BYTES_PER_WORD to MP_BYTES_PER_OBJ_WORD.
The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture.  So rename this config value to better reflect what it
measures, and also prefix it with MP_.

For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

Damien George 64180f0742 extmod/machine_i2c: Add init protocol method for generic I2C bindings.

stijn fad4079778 esp32,unix: Support building C++ code.
Support building .cpp files and linking them into the micropython
executable in a way similar to how it is done for .c files.  The main
incentive here is to enable user C modules to use C++ files (which are put
in SRC_MOD_CXX by py.mk) since the core itself does not utilize C++.

However, to verify build functionality a unix overage test is added.  The
esp32 port already has CXXFLAGS so just add the user modules' flags to it.
For the unix port use a copy of the CFLAGS but strip the ones which are not
usable for C++.

Damien George 39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

Damien George 8f20cdc353 all: Rename absolute time-based functions to include "epoch".
For time-based functions that work with absolute time there is the need for
an Epoch, to set the zero-point at which the absolute time starts counting.
Such functions include time.time() and filesystem stat return values.  And
different ports may use a different Epoch.

To make it clearer what functions use the Epoch (whatever it may be), and
make the ports more consistent with their use of the Epoch, this commit
renames all Epoch related functions to include the word "epoch" in their
name (and remove references to "2000").

Along with this rename, the following things have changed:

- mp_hal_time_ns() is now specified to return the number of nanoseconds
  since the Epoch, rather than since 1970 (but since this is an internal
  function it doesn't change anything for the user).

- littlefs timestamps on the esp8266 have been fixed (they were previously
  off by 30 years in nanoseconds).

Otherwise, there is no functional change made by this commit.

Jim Mussared 52d6eeb409 esp32/boards/sdkconfig.base: Set default IDF log level to ERROR.
This commit changes the default logging level on all esp32 boards to ERROR.
The esp32 port is now stable enough that it makes sense to remove the info
logs to make the output cleaner, and to match other ports.  More verbose
logging can always be reenabled via esp.osdebug().

This also fixes issue #6354, error messages from NimBLE: the problem is
that ble.active(True) will cause the IDF's NimBLE port to reset the
"NimBLE" tag back to the default level (which was INFO prior to this
commit).  Even if the user had previously called esp.osdebug(None), because
the IDF is setting the "NimBLE" tag back to the default (INFO), the
messages will continue to be shown.

The one quirk is that if the user does want to see the additional logging,
then they must call esp.osdebug(0, 3) after ble.active(True) to undo the
IDF setting the level back to the default (now ERROR).  This means that
it's impossible (via Python/esp.osdebug) to see stack-startup logging,
you'd have to recompile with the default level changed back to INFO.

Jim Mussared 311b8519af esp32: Pin MicroPython and NimBLE tasks to core 0.
MicroPython and NimBLE must be on the same core, for synchronisation of the

versions (3.3 and 4.0) there are issues (see e.g. #5489) with running
NimBLE on core 1.

This change - pinning both tasks to core 0 - makes it possible to reliably
run the BLE multitests on esp32 boards.
