8ad30fa433 lib/utils/printf: Make DEBUG_printf implementation more accessible.
The definition of DEBUG_printf doesn't depend on
MICROPY_USE_INTERNAL_PRINTF so move it out of that preprocessor
block and compile it conditionally just depending on the
MICROPY_DEBUG_PRINTERS macro. This allows a port to use DEBUG_printf
while providing it's own printf definition.

1751f5ac7b drivers/sdcard: Do not release CS during the middle of read operations.
It seems that some cards do not tolerate releasing the card (by setting CS
high) after issuing CMD17 (and 18) and raising it again before reading
data. Somehow this causes the 0xfe data start marker not being read and
SDCard.readinto() is spinning forever (or until this byte is in the data).

This seems to fix weird behviour of SDCard.readblocks() returning different
data, also solved hanging os.mount() for my case with a 16GB Infineon card.

This stackexchange answer gives more context:

14ab81e87a esp32: Reduce latency for handling of scheduled Python callbacks.
Prior to this patch there was a large latency for executing scheduled
callbacks when when Python code is sleeping: at the heart of the
implementation of sleep_ms() is a call to vTaskDelay(1), which always
sleeps for one 100Hz tick, before performing another call to
MICROPY_EVENT_POLL_HOOK.

This patch fixes this issue by using FreeRTOS Task Notifications to signal
the main thread that a new callback is pending.

bccf9d3dcf esp8266: Let machine.WDT trigger the software WDT if obj is not fed.
This patch allows scripts to have more control over the software WDT.  If
an instance of machine.WDT is created then the underlying OS is prevented
from feeding the software WDT, and it is up to the user script to feed it
instead via WDT.feed().  The timeout for this WDT is currently fixed and
will be between 1.6 and 3.2 seconds.

b6e5f82ba5 esp8266/modesp: Run ets_loop_iter before/after doing flash erase/write.
A flash erase/write takes a while and during that time tasks may be
scheduled via an IRQ.  To prevent overflow of the task queue (and loss of
tasks) call ets_loop_iter() before and after slow flash operations.

Note: if a task is posted to a full queue while a flash operation is in
progress then this leads to a fault when trying to print out the error
message that the queue is full.  This patch doesn't try to fix this
particular issue, it just prevents it from happening in the first place.

b488a4a848 py/objgenerator: Eliminate need for mp_obj_gen_wrap wrapper instances.
For generating functions there is no need to wrap the bytecode function in
a generator wrapper instance.  Instead the type of the bytecode function
can be changed to mp_type_gen_wrap.  This reduces code size and saves a
block of GC heap RAM for each generator.

d800ed1877 esp8266/esp8266_common.ld: Put mp_keyboard_interrupt in iRAM.
This function may be called from a UART IRQ, which may interrupt the system
when it is erasing/reading/writing flash.  In such a case all code
executing from the IRQ must be in iRAM (because the SPI flash is busy), so
put mp_keyboard_interrupt in iRAM so ctrl-C can be caught during flash
access.

This patch also takes get_fattime out of iRAM and puts it in iROM to make
space for mp_keyboard_interrupt.  There's no real need to have get_fattime
in iRAM because it calls other functions in iROM.

Fixes issue #3897.

d8dc918deb py/compile: Handle return/break/continue correctly in async with.
Before this patch the context manager's __aexit__() method would not be
executed if a return/break/continue statement was used to exit an async
with block.  async with now has the same semantics as normal with.

The fix here applies purely to the compiler, and does not modify the
runtime at all. It might (eventually) be better to define new bytecode(s)
to handle async with (and maybe other async constructs) in a cleaner, more
efficient way.

One minor drawback with addressing this issue purely in the compiler is
that it wasn't possible to get 100% CPython semantics.  The thing that is
different here to CPython is that the __aexit__ method is not looked up in
the context manager until it is needed, which is after the body of the
async with statement has executed.  So if a context manager doesn't have
__aexit__ then CPython raises an exception before the async with is
executed, whereas uPy will raise it after it is executed.  Note that
__aenter__ is looked up at the beginning in uPy because it needs to be
called straightaway, so if the context manager isn't a context manager then
it'll still raise an exception at the same location as CPython.  The only
difference is if the context manager has the __aenter__ method but not the
__aexit__ method, then in that case uPy has different behaviour.  But this
is a very minor, and acceptable, difference.

e328b4593c extmod/moducryptolib: Refactor functions for clean interface with axTLS.
This will allow implementations other than axTLS.

This commit includes additions of checks and clarifications of exceptions
related to user input.

To make the interface cleaner, I've disallowed switching from encrypt to
decrypt in the same object, as this is not always possible with other
crypto libraries (not all libraries have AES_convert_key like axTLS).

CONFIG_NET_NBUF_RX_COUNT no longer exists in Zephyr, for a while. That

so just remove it (instead of switching to what it was renamed to,
CONFIG_NET_PKT_RX_COUNT).

567bc2d6ce extmod/moducryptolib: Add ucryptolib module with crypto functions.
The API follows guidelines of https://www.python.org/dev/peps/pep-0272/,
but is optimized for code size, with the idea that full PEP 0272
compatibility can be added with a simple Python wrapper mode.

The naming of the module follows (u)hashlib pattern.

At the bare minimum, this module is expected to provide:

* AES128, ECB (i.e. "null") mode, encrypt only

Implementation in this commit is based on axTLS routines, and implements
following:

* AES 128 and 256
* ECB and CBC modes
* encrypt and decrypt

967123d42e stm32/mboot: Only compile in code for the USB periph that is being used.
Prior to this patch, if both USB FS and HS were enabled via the

access invalid memory pointed to by an uninitialised Instance.  This patch
fixes this bug by explicitly referencing the peripheral struct.
