Philipp Ebensberger b8c65b174f mimxrt/machine_adc: Add the ADC class to the machine module.
This adds the machine.ADC class with the read_u16() method.  make-pins.py
and supporting files are updated to generate ADC information.

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.

timers will be stopped via finalisers.

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.

Macarthur Inbody 34d4dab683 extmod/modurandom: Add error message when getrandbits has bad value.
The random module's getrandbits() method didn't give a proper error message
when calling it with a value that was outside of the range of 1-32, which
can lead to confusion using this function (which under CPython can accept
numbers larger than 32).  Now instead of simply giving a ValueError it
gives an error message that states that the number of bits is constrained.

Also, since the random module's functions getrandbits() and randint()
differ from CPython, tests have been added to describe these differences.
For getrandbits the relevant documentation is shown and added to the docs.
The same is given for randint method so that the information is more easily
found.

Finally, since the int object lacks the bit_length() method there is a test
for that method also to include within the docs, showing the difference to
CPython.

Jeff Epler d67f4115b4 py/repl: Don't read past the end of import_str.
asan considers that memcmp(p, q, N) is permitted to access N bytes at each
of p and q, even for values of p and q that have a difference earlier.
Accessing additional values is frequently done in practice, reading 4 or
more bytes from each input at a time for efficiency, so when completing
"non_exist<TAB>" in the repl, this causes a diagnostic:

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.
