These are at the moment more or less identical to the Teensy 4.0 files,

robert-hh 2f365d234e mimxrt/machine_rtc: Add the RTC class to the machine module.
Initial version, using the LP RTC clock.  It provides setting the date and
time with rtc.init() or rtc.datetime(), and reading the date and time with
rtc.datetime() or rtc.now().  The method weekday() reports the weekday of
the current date.  It starts with 0 for Monday.

The tuple order for datetime() and now() matches the CPython sequence:
(year, month, day, hour, minute, second, microsecond, TZ).  TZ is ignored
and reported as None.  Microsecond is provided at a best effort.

If a battery is not supplied, the default boot date/time is 1970/1/1 0:0:0.
With a battery, the clock continues to run even when the board is not
powered.  The clock is quite precise.  If not, using rtc.calibration() may
help.

robert-hh dfd4324eb1 mimxrt: Add flash storage support with VFS and littlefs filesystem.
This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.

Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS.  VFS
  will take up most of the available flash. 1M is reserved for code.  9K is
  reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c.  All flashing
  related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
  module.

It uses sample code from CircuitPython supplied under MIT license, which
uses the NXP SDK example code.

Done in collaboration with Philipp Ebensberger aka @alphaFred who
contributed the essential part to enable writing to flash while code is
executing, among other things.

Damien George 0abf6f830c esp8266/boards/GENERIC_512K: Add custom manifest without FS modules.
The 512k build does not have a filesystem so there is no reason to include
the filesystem-related modules.  This commit provides a custom manifest.py
for this board which no longer includes: _boot.py, flashbdev.py,
inisetup.py, upip.py, upip_utarfile.py.  This cuts the build down by about
9k of flash.

Damien George ea81bcf1c0 stm32/mboot: Leave bootloader from thread mode, not from IRQ.
Leaving the bootloader from an IRQ (eg USB or I2C IRQ) will not work if
MBOOT_LEAVE_BOOTLOADER_VIA_RESET is disabled, ie if mboot jumps directly to
the application.  This is because the CPU will still be in IRQ state when
the application starts and IRQs of lower priority will be blocked.

Fix this by setting a flag when the bootloader should finish, and exit the
bootloader always from the main (top level) thread.

This also improves the USB behaviour of mboot: it no longer abruptly
disconnects when the manifest command is sent.

Damien George 748339b281 stm32/uart: Configure pull-up only on RX and CTS, not TX and RTS.
RX and CTS are the input pins and pull-ups are enabled so they don't cause
a problem if left unconnected.  But the output pins don't need a pull up
(they were originally all configured with pull up in commit
8f7491a109).

If needed, the pull-ups can be disabled in Python using machine.Pin after
the UART is constructed.

See issue #4369.

Damien George a96afae90f stm32/sdio: Fix case of SDIO DMA turning off mid transfer.
The DMA driver will turn off DMA if it hasn't been used for an amount of
time (to save power).  The SDIO driver for cyw43 WLAN was not informing the
DMA driver that it was using DMA and there was a chance that the DMA would
turn off in the middle of an SDIO DMA transfer.  The symptoms of this would
be printing of SDIO error messages and a failure to communicate with the
cyw43 WLAN module.

This commit fixes this issue by changing the SDIO driver to use the
dma_nohal_XXX API to initialise and start the DMA.

Damien George 9a0bca2c2a stm32/mboot: Make LEDs and reset-mode selection more configurable.
A board can now customise mboot with:
- MBOOT_LED1, MBOOT_LED2, MBOOT_LED3, MBOOT_LED4: if it needs to have
  different LEDs for mboot compared to the application
- MBOOT_BOARD_LED_INIT: if it needs a fully customised LED init function
- MBOOT_BOARD_LED_STATE: if it needs a fully customised LED state-setting
  function
- MBOOT_BOARD_GET_RESET_MODE: if it needs a fully customised function to
  get the reset mode

With full customisation, the only requirement is a single LED to show the
status of the bootloader (idle, erasing, flashing, etc), which can be
configured to do nothing if needed.

Damien George 6639e282c7 stm32/mboot: Add MBOOT_LEAVE_BOOTLOADER_VIA_RESET option.
It is enabled by default to get the standard behaviour of doing a reset
after it is finished, but can be disabled by a board to jump straight to
the application (likely the board needs to use MBOOT_BOARD_CLEANUP to make
this work).

The application is passed a reset mode of BOARDCTRL_RESET_MODE_BOOTLOADER
if the bootloader was active and entered via a jump.
