Krzysztof Adamski 37d01d4be3 rp2/machine_rtc: Add initial support for RTC.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.

The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.

Damien George 865abba197 esp32/makeimg.py: Load sizes from partition table and verify data fits.
Changes introduced are:
- the application offset is now loaded from the partition table instead of
  being hard-coded to 0x10000
- maximum size of all sections is computed using the partition table
- an error is generated if any section overflows its allocated space
- remaining bytes are printed for each section

Damien George a70a4e6688 py/emitglue: Always flush caches when assigning native ARM code.
Prior to this commit, cache flushing for ARM native code was done only in
the assembler code asm_thumb_end_pass()/asm_arm_end_pass(), at the last
pass of the assembler.  But this misses flushing the cache when loading
native code from an .mpy file, ie in persistentcode.c.

The change here makes sure the cache is always flushed/cleaned/invalidated
when assigning native code on ARM architectures.

This problem was found running tests/micropython/import_mpy_native_gc.py on
the mimxrt port.

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.

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.
