cb3456ddfe stm32: Don't use %lu or %lx for formatting, use just %u or %x.
On this 32-bit arch there's no need to use the long version of the format
specifier.  It's only there to appease the compiler which checks the type
of the args passed to printf.  Removing the "l" saves a bit of code space.

5936168150 extmod/uzlib: Fix C-language sequencing error with uzlib_get_byte calls.
The order of function calls in an arithmetic expression is undefined and so
they must be written out as sequential statements.

Thanks to @dv-extrarius for reporting this issue, see issue #3690.

6681eb809a esp32/modsocket: Correctly handle reading from a peer-closed socket.
If a socket is cleanly shut down by the peer then reads on this socket
should continue to return zero bytes.  The lwIP socket API does not have
this behaviour (it only returns zero once, then blocks on subsequent calls)
so this patch adds explicit checks and logic for peer closed sockets.

fb7dabb971 esp32/README: Add --init to submodule update command.
Add --init to the submodule update example, thus, all submodules get
initialised including the nested (--recursive) ones.  Without it there
might not be a submodule init.

6410e174c5 esp8266: Disable DEBUG_PRINTERS for 512k build.
Disabling this saves around 6000 bytes of code space and gets the 512k
build fitting in the available flash again (it increased lately due to an
increase in the size of the ESP8266 SDK).

db2bdad8a2 tests/pyb: Update tests to run correctly on PYBv1.0.
In adcall.py the pyb module may not be imported, so use ADCAll directly.

In dac.py the DAC object now prints more info, so update .exp file.

In spi.py the SPI should be deinitialised upon exit, so the test can run a
second time correctly.

a03e6c1e05 stm32/irq: Define IRQ priorities directly as encoded hardware values.
For a given IRQn (eg UART) there's no need to carry around both a PRI and
SUBPRI value (eg IRQ_PRI_UART, IRQ_SUBPRI_UART).  Instead, the IRQ_PRI_UART
value has been changed in this patch to be the encoded hardware value,
using NVIC_EncodePriority.  This way the NVIC_SetPriority function can be
used directly, instead of going through HAL_NVIC_SetPriority which must do
extra processing to encode the PRI+SUBPRI.

For a priority grouping of 4 (4 bits for preempt priority, 0 bits for the
sub-priority), which is used in the stm32 port, the IRQ_PRI_xxx constants
remain unchanged in their value.

This patch also "fixes" the use of raise_irq_pri() which should be passed
the encoded value (but as mentioned above the unencoded value is the same
as the encoded value for priority grouping 4, so there was no bug from this
error).

266446624f stm32/dma: Always deinit/reinit DMA channels on L4 MCUs.
The problem is the existing code which tries to optimise the
reinitialisation of the DMA breaks the abstraction of the HAL.  For the
STM32L4 the HAL's DMA setup code maintains two private vars (ChannelIndex,
DmaBaseAddress) and updates a hardware register (CCR).

In HAL_DMA_Init(), the CCR is updated to set the direction of the DMA.
This is a problem because, when using the SD Card interface, the same DMA
channel is used in both directions, so the direction bit in the CCR must
follow that.

A quick and effective fix for the L4 is to simply call HAL_DMA_DeInit() and
HAL_DMA_Init() every time.

d43c737756 py/stream: Use uPy errno instead of system's for non-blocking check.
This is a more consistent use of errno codes.  For example, it may be that
a stream returns MP_EAGAIN but the mp_is_nonblocking_error() macro doesn't
catch this value because it checks for EAGAIN instead (which may have a
different value than MP_EAGAIN when MICROPY_USE_INTERNAL_ERRNO is enabled).

96740be357 py/mperrno: Define MP_EWOULDBLOCK as EWOULDBLOCK, not EAGAIN.
Most modern systems have EWOULDBLOCK aliased to EAGAIN, ie they have the
same value.  But some systems use different values for these errnos and if
a uPy port is using the system errno values (ie not the internal uPy
values) then it's important to be able to distinguish EWOULDBLOCK from
EAGAIN.  Eg if a system call returned EWOULDBLOCK it must be possible to
check for this return value, and this patch makes this now possible.

9f1eafc380 tests/io/bytesio_ext2: Remove dependency on specific EINVAL value
If MICROPY_USE_INTERNAL_ERRNO is disabled, MP_EINVAL is not guaranteed
to have the value 22, so we cannot depend on OSError(22,).
Instead, to support any given port's errno values, without relying
on uerrno, we just check that the args[0] is positive.

8c12f1d916 stm32/adc: Add support for H7 MCU series.
ADC3 is used because the H7's internal ADC channels are connected to ADC3
and the uPy driver doesn't support more than one ADC.

Only 12-bit resolution is supported because 12 is hard-coded and 14/16 bits
are not recommended on some ADC3 pins (see errata).

Values from internal ADC channels are known to give wrong values at
present.

999c8b9711 esp32/modsocket: Add support for registering socket event callbacks.
The esp8266 uses modlwip.c for its usocket implementation, which allows to
easily support callbacks on socket events (like when a socket becomes ready
for reading).  This is not as easy to do for the esp32 which uses the
ESP-IDF-provided lwIP POSIX socket API.  Socket events are needed to get
WebREPL working, and this patch provides a way for such events to work by
explicitly polling registered sockets for readability, and then calling the
associated callback if the socket is readable.
