bde222ce84 mimxrt/modmachine: Implement machine.bootloader().
If a board defines a custom bootloader entry function it will be called
first, if not and the ROM API supports RUN bootloader API, then
`machine.bootloader()` will jump to the ROM serial downloader in USB mode.

8b72721b29 mimxrt/mpconfigport: Allow configuring different network interfaces.
This commit allows boards to disable Ethernet and keep the networking stack
enabled, to use an alternate networking interface, such as WiFi.

Note that the `network` and `socket` modules are now enabled by default for
a board.

944b4c2058 mimxrt/boards/MIMXRT1064_EVK: Fix board config to use internal flash.
This commit is necessary to make MicroPython work on this eval kit out of
the box, as the eval kit ships with the HyperFlash physically disconnected
from the bus (refer to the schematics or the user guide) and the QSPI
connected instead, but the fuses/board/pins are configured to boot from
internal flash (on FlexSPI2).

Note that enabling the HyperFlash is not trivial, as it requires soldering
and desoldering of many small footprint resistors and changing fuses.

c046b23ea2 shared/runtime/pyexec: Don't allow Ctrl+C to interrupt frozen boot code.
Helps prevent the filesystem from getting formatted by mistake, among other
things.  For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).

Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state.  If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application.  The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it.  But defining
"long enough" is impossible for all the different boards and their possible
behaviour.  The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C.  That code then effectively
acts like normal C start-up code, which also cannot be interrupted.

Note: on the stm32 port this was never seen as an issue because all
start-up code is in C.  But now other ports start to put more things in
_boot.py and so this problem crops up.

db4b416ea8 mimxrt/pendsv: Clean up PendSV code.
The dispatch active flag is only set once and never reset, so it will
always call the dispatch handler (once enabled), and it's not really
needed because it doesn't make things more efficient.

Also remove unused included headers.

38e7b842c6 ports: Implement simple write polling for stdout.
This is a best-effort implementation of write polling.  It's difficult to
do correctly because if there are multiple output streams (eg UART and USB
CDC) then some may not be writeable while others are.  A full solution
should also have a return value from mp_hal_stdout_tx_strn(), returning the
number of bytes written to the stream(s).  That's also hard to define.

The renesas-ra and stm32 ports already implement a similar best-effort
mechanism for write polling.

Fixes issue #11026.

a377302623 extmod/modnetwork: Add network.hostname() and network.country().
This provides a standard interface to setting the global networking config
for all interfaces and interface types.

For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).

For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.

Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).

Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

de1f1dd164 shared/runtime/softtimer: Use consistently the same clock source.
Before, both uwTick and mp_hal_ticks_ms() were used as clock source.  That
assumes, that these two are synchronous and start with the same value,
which may be not the case for all ports.  If the lag between uwTick and
mp_hal_ticks_ms() is larger than the timer interval, the timer would either
rush up until the times are synchronous, or not start until uwTick wraps
over.

As suggested by @dpgeorge, MICROPY_SOFT_TIMER_TICKS_MS is now used in
softtimer.c, which has to be defined in a port's mpconfigport.h with
the variable that holds the SysTick counter.

Note that it's not possible to switch everything in softtimer.c to use
mp_hal_ticks_ms() because the logic in SysTick_Handler that schedules
soft_timer_handler() uses (eg on mimxrt) the uwTick variable directly
(named systick_ms there), and mp_hal_ticks_ms() uses a different source
timer.  Thus it is made fully configurable.

3446d440f6 shared/runtime/gchelper: Drop cpu directive from ARM asm helpers.
This drops the `.cpu` directive from the ARM gchelper_*.s files.  Having
this directive breaks the linker when targeting older CPUs (e.g. `-mthumb
-mthumb-interwork` for `-mcpu=arm7tdmi`).  The actual target CPU should be
determined by the compiler options.

The exact CPU doesn't actually matter, but rather the supported assembly
instruction set.  So the files are renamed to *_thumb1.s and *thumb2.s to
indicate the instruction set support instead of the CPU support.

5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.

The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
  being the 1GB interface.

The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.

This work was done in collaboration with @alphaFred.

8874a09119 extmod/mbedtls: Enable elliptic curve DH and DSA cryptography.
This is necessary to access sites that only support these protocols.

The rp2 port already has ECDH enabled, so this just adds ECDSA there.  The
other ports now gain both ECDH and ECDSA.  The code size increase is:

- rp2 (PICO_W): +2916 bytes flash, +24 bytes BSS
- stm32 (PYBD_SF6): +20480 bytes flash, +32 bytes data, +48 bytes BSS
- mimxrt (TEENSY41): +20708 bytes flash, +32 bytes data, +48 bytes BSS
- unix (standard x86-64): +39344 executable, +1744 bytes data, +96 BSS

This is obviously a large increase in code size.  But there doesn't seem to
be any other option because without elliptic curve cryptography devices are
partially cut off from the internet.  For use cases that require small
firmware size, they'll need to build custom firmware with a custom mbedtls
config.

6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".
