8b061f2d79 zephyr: Fix floating point configuration.
Zephyr renamed CONFIG_FLOAT to CONFIG_FPU to better reflect its semantics
of enabling the hardware floating point unit (FPU) rather than enabling
toolchain-level floating point support (i.e., software floating point for
FPU-less socs).

38b4f1569e zephyr: Fix and rename stacks_analyze function in zephyr module.
Zephyr deprecated and then removed its stack_analyze function because it
was unsafe.  Use the new zephyr thread analyzer instead and rename the
MicroPython function to zephyr.thread_analyze() to be more consistent with
the implementation.

Tested on mimxrt1050_evk.

The output now looks like this:

>>> zephyr.thread_analyze()
Thread analyze:

05e5d411b5 mimxrt/boards: Set __heap_size__ to 0 in MIMXRT1011.ld.
Do not use the traditional C heap in order to save memory, because the
traditional C heap is unused in MicroPython.

2934e41df0 docs/esp8266: Add quickref documentation for UART on esp8266.
This patch adds quickref documentation for the change in commit
afd0701bf7.  This commit added the ability to
disable the REPL and hence use UART0 for serial communication on the
esp8266, but was not previously documented anywhere.

The text is largely taken from the commit message, with generic information
on using the UART duplicated from the Wipy quickref document.

f3062b5cbd py/obj.h: Clarify comments about mp_map_t is_fixed and is_ordered.
Long ago, prior to 0ef01d0a75, fixed and
ordered maps were the same setting with the "table_is_fixed_array" member
of mp_map_t.  But these settings are actually independent, and it is
possible to have is_fixed=1, is_ordered=0 (although this can currently
only be done by tools/cc1).  So update the comments to reflect this.

95cbe6b65e py/objtype: Use mp_obj_dict_copy() for creating obj.__dict__ attribute.
The resulting dict is now marked as read-only (is_fixed=1) to enforce the
fact that changes to this dict will not be reflected in the class instance.

This commit reduces code size by about 20 bytes, and should be more
efficient because it creates a direct copy of the dict rather than
reinserting all elements.

28370c0450 py/objtype: Add __dict__ attribute for class objects.
The behavior mirrors the instance object dict attribute where a copy of the
local attributes are provided (unless the dict is read-only, then that dict
itself is returned, as an optimisation).  MicroPython does not support
modifying this dict because the changes will not be reflected in the class.

The feature is only enabled if MICROPY_CPYTHON_COMPAT is set, the same as
the instance version.

fix from upstream TinyUSB in the future.

- method overloads must not be declared as a separate method or must
  use :noindex:
- 2 cases where `` should have been used instead of `

834b482e67 examples/bluetooth: Fix incorrect value of BR/EDR flag in advertising.
According to Supplement to the Bluetooth Core Specification v8 Part A
1.3.1, to support BR/EDR the code should set the fifth bit (Simultaneous LE
and BR/EDR to Same Device Capable (Controller)) and fourth bit
(Simultaneous LE and BR/EDR to Same Device Capable (Host)) of the flag.

8b7ae4e099 extmod/modbluetooth: Support bigger characteristic values.
The ring buffer previously used a single unsigned byte field to save the
length, meaning that it would overflow for large characteristic value
responses.

With this commit it now use a 16-bit length instead and has code to
explicitly truncate at UINT16_MAX (although this should be impossible to
achieve in practice).

e6881f0829 extmod/modbluetooth: Make modbluetooth event not a bitfield.
There doesn't appear to be any use for only triggering on specific events,
so it's just easier to number them sequentially.  This makes them smaller
values so they take up only 1 byte in the ringbuf, only 1 byte for the
opcode in the bytecode, and makes room for more events.

Also add a couple of new event types that need to be implemented (to avoid
re-numbering later).

And rename _COMPLETE and _STATUS to _DONE for consistency.

In the future the "trigger" keyword argument can be reinstated by requiring
the user to compute the bitmask, eg:

    ble.irq(handler, 1 << _IRQ_SCAN_RESULT | 1 << _IRQ_SCAN_DONE)

02cc4462b7 mimxrt: Add initial impl of machine.LED class, and basic pin support.
This commit implements an LED class with rudimentary parts of a pin C API
to support it.  The LED class does not yet support setting an intensity.

This LED class is put in the machine module for the time being, until a
better place is found.

One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.

8e591d412a minimal: Make build more flexible and work as 64-bit build.
Changes are:
- string0 is no longer built when building for host as the target, because
  it'll be provided by the system libc and may in some cases clash with the
  system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
  both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
  from mpconfigport.h to make the configuration a bit more minimal, eg as
  a better starting point for new ports.

8f642677f7 tools/codeformat.py: Add verbose option to pass to uncrustify and black.
This adds a new command line option `-v` to `tools/codeformat.py` to enable
verbose printing of all files that are scanned.

Normally `uncrustify` and `black` are called with the `-q` option so
setting verbose suppresses the `-q` option and on `black` also enables the
`-v` option which makes it print out all file names matching the filter
similar to how `uncrustify` does by default.

f03d030080 powerpc/uart: Choose which UART to use at build time, not runtime.
Microwatt may have firmware that places data in r3, which was used to
detect microwatt vs powernv.  This breaks the existing probing of the UART
type in this powerpc port.

Instead build only the appropriate UART into the firmware, selected by
passing the option UART=potato or UART=lpc_serial to the Makefile.

A future enhancement would be to parse the device tree and configure
MicroPython based on the settings.
