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.

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.

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.

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.

irq.h is included by py/mphal.h but it's better to be explicit, eg if mboot
uses powerctrlboot.c.

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.

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.
Fixes issue #6167.
With only `sp_func_proto_paren = remove` set there are some cases where
uncrustify misses removing a space between the function name and the
opening '('. This sets all of the related options to `force` as well.
There are a maximum of 8 USB endpoints and each has 2 buffer slots
(in/out). This commit add support for up to 8 endpoints and adds FIFO
configuration for USB profiles with 2xVCP on MCUs that have device-only USB
peripherals.
Tested on NUCLEO_WB55 in 2xVCP, 2xVCP+MSC and 2xVCP+MSC+HID mode.

The ESP32 RMT peripheral has hardware support for a carrier frequency, and
this commit exposes it to Python with the keyword arguments carrier_freq
and carrier_duty_percent in the constructor. Example usage:
r = esp32.RMT(0, pin=Pin(2), clock_div=80, carrier_freq=38000, carrier_duty_percent=50)
Zephyr renamed CONFIG_FLOAT to CONFIG_FPU to better reflect its semantics
of enabling the hardware floating point unit (FPU) rather than enabling
toolchain-level floating point support (i.e., software floating point for
FPU-less socs).
Zephyr deprecated and then removed its stack_analyze function because it
was unsafe. Use the new zephyr thread analyzer instead and rename the
MicroPython function to zephyr.thread_analyze() to be more consistent with
the implementation.
Tested on mimxrt1050_evk.
The output now looks like this:
>>> zephyr.thread_analyze()
Thread analyze:

rx_workq : unused 1320 usage 180 / 1500 (12 %)

Sending more than 64 bytes to the USB CDC endpoint in HS mode will lead to
a hard crash. This commit fixes the issue, although there may be a better
fix from upstream TinyUSB in the future.
With this commit the code should work correctly regardless of the size of
StackType_t (it's actually 1 byte in size for the esp32's custom FreeRTOS).
Fixes issue #6072.
This commit implements an LED class with rudimentary parts of a pin C API
to support it. The LED class does not yet support setting an intensity.
This LED class is put in the machine module for the time being, until a
better place is found.
One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.
Changes are:
- string0 is no longer built when building for host as the target, because
it'll be provided by the system libc and may in some cases clash with the
system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
from mpconfigport.h to make the configuration a bit more minimal, eg as
a better starting point for new ports.
Microwatt may have firmware that places data in r3, which was used to
detect microwatt vs powernv. This breaks the existing probing of the UART
type in this powerpc port.
Instead build only the appropriate UART into the firmware, selected by
passing the option UART=potato or UART=lpc_serial to the Makefile.
A future enhancement would be to parse the device tree and configure
MicroPython based on the settings.
