b4dc4c5b9a stm32/mboot: Use additional CFLAGS to compile string0.c.
This is the same as a902b69dd5 but applied to
mboot's Makefile.

81a7293ed6 stm32/mboot: Set VTOR on start up to ensure it has the correct value.
Commit 8675858465 switched to using the CMSIS
provided SystemInit function which sets VTOR to 0x00000000 (previously it
was 0x08000000).  A VTOR of 0x00000000 will be correct on some MCUs but not
on others where the built-in bootloader is remapped to this address, via
__HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH().

To make sure mboot has the correct vector table, this commit explicitly
sets VTOR to the correct value of 0x08000000.

8675858465 stm32/mboot: Use CMSIS system source code for SystemInit function.
There's no need to duplicate this functionality in mboot, the code provided
in stm32lib/CMSIS does the same thing and makes it easier to support other
MCU series.

a8778c8dc8 stm32/mboot: Use flash routines from main stm32 code rather than custom.
The flash functions in ports/stm32/flash.c are almost identical to those in
ports/stm32/mboot/main.c, so remove the duplicated code in mboot and use
instead the main stm32 code.  This also allows supporting other MCU series.

afd47d58ac stm32/flash: Make flash C-API reusable, and funcs return an error code.
This commit makes the low-level flash C functions usable by code other than
flashbdev.c (eg by mboot).  Changes in this commit are:
- flash_erase() and flash_write() now return an errno error code, a
  negative value on error.
- flash_erase() now automatically locks the flash, as well as unlocking it.
- flash_write() now automatically unlocks the flash, as well as locking it.
- flashbdev.c is modified for the above changes.

5f3c2f1fa8 stm32/irq: Clean up irq.h so it does not depend on core uPy defines.
The irq.h file now just provides low-level IRQ definitions and priorities.
All Python binding definitions are moved to modmachine.h, with some
renaming of pyb -> machine, and also the machine_idle definition (was
pyb_wfi) is moved to modmachine.c.

The cc3200 and teensy ports are updated to build with these changes.

3a9d948032 esp32/esp32_rmt: Call rmt_driver_install before rmt_config.
Otherwise the RMT will repeat pulses when using loop(True).  This repeating
is due to a bug in the IDF which will be fixed in an upcoming release, but
for now the accepted workaround is to swap these calls, which should still
work in the fixed version of the IDF.

a51eef4471 tests/basics: Add tests for variable annotations. 2020-06-16 23:18:01 +10:00

f2e267da68 py/compile: Implement PEP 526, syntax for variable annotations.
This addition to the grammar was introduced in Python 3.6.  It allows
annotating the type of a varilable, like:

    x: int = 123
    s: str

The implementation in this commit is quite simple and just ignores the
annotation (the int and str bits above).  The reason to implement this is
to allow Python 3.6+ code that uses this feature to compile under
MicroPython without change, and for users to use type checkers.

In the future viper could use this syntax as a way to give types to
variables, which is currently done in a bit of an ad-hoc way, eg
x = int(123).  And this syntax could potentially be used in the inline
assembler to define labels in an way that's easier to read.

1783950311 py/compile: Implement PEP 572, assignment expressions with := operator.
The syntax matches CPython and the semantics are equivalent except that,
unlike CPython, MicroPython allows using := to assign to comprehension
iteration variables, because disallowing this would take a lot of code to
check for it.

The new compile-time option MICROPY_PY_ASSIGN_EXPR selects this feature and
is enabled by default, following MICROPY_PY_ASYNC_AWAIT.

This is the result of running...

    uncrustify -c tools/uncrustify.cfg --update-config-with-doc -o tools/uncrustify.cfg

...with some manual fixups to correct places where it changed things it

Essentially it just adds new config parameters introduced in v0.71.0
