93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct.
One can instead lookup __name__ in the modules dict to get the value.

b0a46900de stmhal: Use attribute to avoid inlining.
Use MP_NOINLINE macro to avoid inlining of init_flash_fs. This helps
to keep stack usage of main() low.

4874bde104 stmhal/boards: For OLIMEX_E407, enable UART1 and fix I2C1 mapping.
UART1 can be used even if the switch is enabled.  The schematics for this
board make I2C1 available on PB8/PB9, even though it can also be mapped
to PB6/PB7.

See #2396 and #2427.

1ba516f475 stmhal/extint: Force 0 to 1 transition on swint().
If a user tries to call `swint()` while interrupt is disabled the flag in
SWIER is set but the interrupt is not triggered and therefore the SWIER bit
is not cleared.  When the interrupt is again enabled the next call to
`swint()` won't trigger the IRQ because a 0 to 1 transition will not occur.

06a1194300 stmhal/{accel,lcd}: use GPIO_{set,clear}_pin
different HAL versions implement GPIO differently (BSRR vs BSRRH+BSRRL),
this way both drivers are portable between different HAL's

d89de18f40 stmhal/lcd: De-assert chip select after completing SPI transmission.
The LCD interface library fails to deassert the chip select of the LCD
after an SPI transmission.  Consequently using the SPI with other
peripherals disturbs the state of the LCD.  This patch changes
lcd.lcd_out() to deassert CS after each transmission to the LCD.

f3b5480be7 stmhal,cc3200,esp8266: Consistently use PWRON_RESET constant.
machine.POWER_ON is renamed to machine.PWRON_RESET to match other
reset-cause constants that all end in _RESET.  The cc3200 port keeps a
legacy definition of POWER_ON for backwards compatibility.

e2ac8bb3f1 py: Add MICROPY_USE_INTERNAL_PRINTF option, defaults to enabled.
This new config option allows to control whether MicroPython uses its own
internal printf or not (if not, an external one should be linked in).
Accompanying this new option is the inclusion of lib/utils/printf.c in the
core list of source files, so that ports no longer need to include it
themselves.

fedab995ee stmhal: Set STM32F7DISC CPU Frequency to 216 MHz
This set the CPU frequency to 216 MHz (the max) and
leaves the USB Frequency at 48 MHz.

9c04ef2a67 unix,stmhal,esp8266: When find'ing frozen files don't use extra slash.
This extra forward slash for the starting-point directory is unnecessary
and leads to additional slashes on Max OS X which mean that the frozen
files cannot be imported.

fc73c9b4b2 stmhal/modusocket: set self->nic to MP_OBJ_NULL after socket close

c6983e3ce0 stmhal: Fix timer capture/compare interrupt handling for TIM1 and TIM8.
It turns out that TIM1 and TIM8 have their own Capture/Compare
interrupt vector. For all of the other timers, the capture/compare
interrupt vector is the same as the update vector.

So we need to add handlers for these vectors and enable them
when using capture/compare callbacks.

During testing of this, I also found that passing a channel callback
into the channel constructor would not enable interrupts properly.

I tested using:
```
>>> pyb.Timer(1, freq=4).channel(1, pyb.Timer.OC_TOGGLE, callback=lambda t: print('.', end=''))
```
I tested the above with channels 1, 4, and 8

675d1c9c60 ports: Remove typedef of machine_ptr_t, it's no longer needed.
This type was used only for the typedef of mp_obj_t, which is now defined
by the object representation.  So we can now remove this unused typedef,
to simplify the mpconfigport.h file.

af9889f99a stmhal/adc.c: Get ADC working on STM32L4 MCUs.
Fixing Issue #2243. Main problems were:

- HAL_ADC_GetState(adcHandle) may return other bits set (not only
  HAL_ADC_STATE_EOC_REG) when called - so I AND-ed it out as proposed by
  mattbrejza in Issue #2243.
- ADC Pin has to be configured as GPIO_MODE_ANALOG_ADC_CONTROL not only
  GPIO_MODE_ANALOG.
- Resolved ADC resolution L4 specific (Use L4 define ADC_RESOLUTION_12B).
- Changed setting of Init.EOCSelection toADC_EOC_SINGLE_CONV for L4.
- Added call to ADC_MultiModeTypeDef as this is done on a STM32Cube
  generated project too.
- Clean up: Configuration of ADC is done only in ONE function not the same
  is done in two functions.

Test is done on PA5 pin of STM32L4Discovery-Kit which is connected to the
DOWN button.

Thanks to mattbrejza for discovering the bug.

87981fc517 stmhal/sdcard: Allow to do unaligned read-from/write-to SD card.
For example, the following code now works with a file on the SD card:

    f = open('test', 'rb') # test must be 1024 bytes or more in size
    f.seek(511)
    f.read(513)

Also works for writing.
