f92f7dd2bc stmhal/boards: For STM32F411DISC, change I2C pin according to datasheet.
The pin had to be changed to get the I2C sensors on board to work.

16a3534ad4 unix/moduselect: Implement ipoll() method with no-allocation policy.
ipoll() allows to poll streams without allocating any memory: this method
returns an iterator (a poll object itself), and the iterator yields
preallocated "callee-owned tuple" with polling results for each active
stream. The only operation a caller is allowed to do with this tuple is
extracting values from it (storing the tuple as a whole somewhere is
not allowed).

cc2dbdd1fe py/emitbc: Produce correct line number info for large bytecode chunks.
Previous to this patch, for large chunks of bytecode that originated from
a single source-code line, the bytecode-line mapping would generate
something like (for 42 bytecode bytes and 1 line):

  BC_SKIP=31  LINE_SKIP=1
  BC_SKIP=11  LINE_SKIP=0

This would mean that any errors in the last 11 bytecode bytes would be
reported on the following line.  This patch fixes it to generate instead:

  BC_SKIP=31  LINE_SKIP=0
  BC_SKIP=11  LINE_SKIP=1

18e6569166 py/objtype: Implement __delattr__ and __setattr__.
This patch implements support for class methods __delattr__ and __setattr__
for customising attribute access.  It is controlled by the config option
MICROPY_PY_DELATTR_SETATTR and is disabled by default.

ec7dc7f8d7 extmod/vfs: Allow to mount a block device, not just a VFS object.
If the mounted object doesn't have a "mount" method then assume it's a
block device and try to detect the filesystem.  Since we currently only
support FAT filesystems, the behaviour is to just try and create a VfsFat
object automatically, using the given block device.

181f7d1450 extmod/machine_signal: Implement Signal .on() and .off() methods.
Each method asserts and deasserts signal respectively. They are equivalent
to .value(1) and .value(0) but conceptually simpler (and may help to avoid
confusion with inverted signals, where "asserted" state means logical 0
output).

7ae9bee790 stmhal/Makefile: Drop use of -mabi=aapcs-linux; link libgcc by default.
The aapcs-linux ABI is not required, instead the default aapcs ABI is
enough.  And using the default ABI means that the provided libgcc will now
link with the firmware without warnings about variable vs fixed enums.

Although the binary size increases by about 1k, RAM usage is slightly
decreased.  And libgcc may prove useful in the future for things like
long-long division.

aa34c553ec py/nlr: Fix execstack builds for ARM.
It seems that the gcc toolchain on the RaspberryPi
likes %progbits instead of @progbits. I verified that
%progbits also works under x86, so this should
fix #2848 and fix #2842

I verified that unix and mpy-cross both compile
on my RaspberryPi and on my x64 machine.

af622eb2a6 py/map: Change mp_uint_t to size_t where appropriate.
The internal map/set functions now use size_t exclusively for computing
addresses.  size_t is enough to reach all of available memory when
computing addresses so is the right type to use.  In particular, for
nanbox builds it saves quite a bit of code size and RAM compared to the
original use of mp_uint_t (which is 64-bits on nanbox builds).

a25aa2bcc3 py/asmxtensa.h: Explicitly cast args to 32-bits so left-shift is legal.
For archs that have 16-bit pointers, the asmxtensa.h file can give compiler
warnings about left-shift being greater than the width of the type (due to
the inline functions in this header file).  Explicitly casting the
constants to uint32_t stops these warnings.

Damien George
dee47949cc extmod/machine_spi: Remove EVENT_POLL_HOOK from soft-SPI transfer func.
SPI needs to be fast, and calling the EVENT_POLL_HOOK every byte makes it
unusable for ports that need to do non-trivial work in the EVENT_POLL_HOOK
call.  And individual SPI transfers should be short enough in time that
EVENT_POLL_HOOK doesn't need to be called.

If something like this proves to be needed in practice then we will need
to introduce separate event hook macros, one for "slow" loops (eg
select/poll) and one for "fast" loops (eg software I2C, SPI).

d3bb3e38df tests/pyb: Adjust tests so they can run on PYB and PYBLITE.
A few tests still fail on PYBLITE, and that's due to differences in the
available peripheral block numbers on the different MCUs (eg I2C(2)
exists on one, but it's I2C(3) on the other).

27c149efe0 stmhal: Add pyb.fault_debug() function, to control hard-fault behaviour.
This new function controls what happens on a hard-fault:
- debugging disabled: board will do a reset
- debugging enabled: board will print registers and stack and flash LEDs

The default is disabled, ie to do a reset.  This is different to previous
behaviour which flashed the LEDs and waited indefinitely.

b7d27e31e8 cc3200: Refactor "ticks" functions to use common extmod implementation.
The port now uses the common mp_utime_ticks_{ms,us,cpu,add,diff} functions
from extmod/utime_mphal.c.

The mp_utime_sleep_XXX functions are still cc3200-specific because they
handle the GIL differently to the ones in extmod.

The files misc/mpsystick.[ch] have been removed because they contain 2
unused functions, and the other remaining function is renamed to
mp_hal_ticks_us and moved to hal/cc3200_hal.c.

Paul Sokolovsky
d5e9ab6e61 extmod/machine_pulse: Make time_pulse_us() not throw exceptions.
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.
