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.

69b93527d5 ports: Make BOARD default from BOARD_DIR in Makefile's.
This allows:

    $ make BOARD_DIR=path/to/board

to infer BOARD=board, rather than the previous behavior that required
additionally setting BOARD explicitly.

Also makes the same change for VARIANT_DIR -> VARIANT on Unix.

This work was funded through GitHub Sponsors.

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.

d6d8722558 extmod: Make extmod.mk self-contained.
This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.

Make all extmod variables (src, flags, etc) private to extmod.mk.

Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.

Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

8e54225140 mimxrt: Format the firmware image to match the new teensy loader.
The new teensy loader keeps the file system under certain conditions:
- The file size is properly set in the file header.
- The header version is 4.3

These changes are implemented here, requiring a backport of
fsl_flexspi_nor_boot.c.  There is still a problem with the command line
version of the teensy loader, which fails on the first attempt.  At the
second attempt it works.  The GUI version of the teensy loader is fine.

fdfe4eca74 ports: Always include debug information in the ELF.
For bare metal ARM & xtensa targets, passing -g will make the ELF file
larger but doesn't change the binary size.  However, this means tools like
gdb, addr2line, etc can extract source-level information from the ELF.

Also standardise -ggdb to -g, these produce the exact same ELF file on
arm-none-eabi-gcc and will use DWARF format for all these ports.

80339f1a33 ports: Adapt mimxrt, nrf and rp2 ports to work with latest TinyUSB.
rp2: change tud_task() to tud_task_ext().

mimxrt: use lib/tinyusb/src/portable/chipidea/ci_hs/dcd_ci_hs.c instead of
lib/tinyusb/src/portable/nxp/transdimension/dcd_transdimension.c.

nrf: add a definition for the changed tud_task().  tud_task() is changed
to tud_task_ext(), and the #define for backward compatibility is in
src/device/usbd.h.

The items I know which are fixed with this version:
- Fix for the SAMD USB lock-up.
- Support the MIMXRT11XX series of MCUs.
- Fix a wrong pin definition for MIMXRT1050_EVKB.

Tested with the MIMXRT boards, rp2 Pico, SAMD boards, nrf board.

a0432ed9cb mimxrt: Update port to work with new nxp_driver v2.10.
The nxp_driver v2.10 allows for/requires some changes to the code:

- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
  library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI.  It's faster and interferes less with
  other modules.
- Use the clock_config.c files of library v2.8.5.  The mimxrt files keeps
  the clock_config.c files from Verson 2.8.5.  With clock_config.c from
  v2.10, the boards do not work.  Refactoring of the clock set-up is on the
  to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
  code.
- The clock_config.* files are moved from the board-specific directories to
  the boards directory and given a MCU related name.

Thanks for the hint, Damien. The DEBUG build got very large recently.
The major difference is, that inline function are now inlined and

that the code speed si now close to the final code. It could be worse

81f706aee4 mimxrt: Support PWM using the FLEXPWM and QTMR modules.
Frequency range 15Hz/18Hz to > 1 MHz, with decreasing resolution of the
duty cycle.  The basic API is supported as documentated, except that
keyword parameters are accepted for both the instatiaton and the
PWM.init() call.

Extensions: support PWM for channel pairs.  Channel pairs are declared by
supplying 2-element tuples for the pins.  The two channels of a pair must
be the A/B channel of a FLEXPWM module.  These form than a complementary
pair.

Additional supported keyword arguments:

- center=value Defines the center position of a pulse within the pulse
  cycle.  The align keyword is actually shortcut for center.

- sync=True|False: If set to True, the channels will be synchronized to a
  submodule 0 channel, which has already to be enabled.

- align=PWM.MIDDLE | PMW.BEGIN | PWM.END. It defines, whether synchronized
  channels are Center-Aligned or Edge-aligned.  The channels must be either
  complementary a channel pair or a group of synchronized channels.  It may
  as well be applied to a single channel, but withiout any benefit.

- invert= 0..3. Controls ouput inversion of the pins.  Bit 0 controls the
  first pin, bit 1 the second.

- deadtime=time_ns time of complementary channels for delaying the rising
  slope.

- xor=0|1|2 xor causes the output of channel A and B to be xored.  If
  applied to a X channel, it shows the value oif A ^ B.  If applied to an A
  or B channel, both channel show the xored signal for xor=1.  For xor=2,
  the xored signal is split between channels A and B.  See also the
  Reference Manual, chapter about double pulses.  The behavior of xor=2 can
  also be achieved using the center method for locating a pulse within a
  clock period.

The output is enabled for board pins only.

CPU pins may still be used for FLEXPWM, e.g. as sync source, but the signal
will not be routed to the output.  That applies only to FLEXPWM pins.  The
use of QTMR pins which are not board pins will be rejected.

As part of this commit, the _WFE() statement is removed from
ticks_delay_us64() to prevent PWM glitching during calls to sleep().

c2e4759cfa mimxrt/modmachine: Implement machine.WDT() and machine.reset_cause().
The API follows that of rp2, stm32, esp32, and the docs.

    wdt=machine.WDT(0, timeout)

        Timeout is given in ms. The valid range is 500 to 128000 (128
        seconds) with 500 ms granularity. Values outside of that range will
        be silently aligned.

    wdt.feed()

        Resets the watchdog timer (feeding).

    wdt.timeout_ms(value)

        Sets a new timeout and feeds the watchdog.

        This is a new, preliminary method which is not yet documented.

    reset_cause = machine.reset_cause()

        Values returned:

        1  Power On reset
        3  Watchdog reset
        5  Software reset: state after calling machine.reset()

More elaborate API functions are supported by the MCU, like an interrupt
called a certain time after feeding.  But for port cosistency that is not
implemented.

- MIMXRT1020_EVK
- MIMXRT1050_EVK
- MIMXRT1060_EVK

Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK.
Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working.
Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not
tested lacking suitable boards.

Tested functions are:
- ping works bothway
- simple UDP transfer works bothway
- ntptime works
- the ftp server works
- secure socker works
- telnet and webrepl works

The MAC address is 0x02 plus 5 bytes from the manifacturing info field,
which can be considered as unique per device.

Some boards do not wire the RESET and INT pin of the PHY transceiver.  For
operation, these are not required.  If they are defined, they will be used.

0d7366c912 mimxrt: Rework flash configuration.
- Moves definition of BOARD_FLASH_SIZE and other header files related to
	flash configuration into the Makefile.
- Adds board specific clock_config.h.
- Adds board.h, pin_mux.h, and peripherals.h as they are
	required by NXP MCU SDK in order to use our own clock_config.h.
- Renames board specific FlexSPI configuration files.
- Updates flash frequency of MIMXRT1020_EVK
- Creates separated flash_config files for QSPI NOR and
	QSPI Hyper flash.
- Unifies VFS start address to be @ 1M for 1010 and 1020 boards.
- Unifies 1050EVK boards
- Adds support to both NOR and HyperFlash on boards with
	both capabilities.
- Adds automatic FlexRAM initialization to start-up code based on
	linker script and NXP HAL.
- Applies code formatting to all files in mimxrt port.

With this change the flash configuration is restructured and
organized. This simplifies the configuration process and
provides a better overview of each board's settings. With the integration
of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better
control of the settings and clock configurations. Furthermore the
implementation of an explicit FlexRAM setup improves the system
performance and allows for performance tuning.

	`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
        to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!

SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.
