Jeff Epler dd6e7f5a8a mimxrt10xx: Add required header for NORETURN definition 2020-09-28 18:56:01 -05:00
Jeff Epler 726dcdb60a Add some NORETURN attributes
I have a function where it should be impossible to reach the end, so I put in a safe-mode reset at the bottom:
```
int find_unused_slot(void) {
    // precondition: you already verified that a slot was available
    for (int i=0; i<NUM_SLOTS; i++) {
        if( slot_free(i)) {
            return i;
        }
    }
    safe_mode_reset(MICROPY_FATAL_ERROR);
}
```
However, the compiler still gave a diagnostic, because safe_mode_reset was not declared NORETURN.

So I started by teaching the compiler that reset_into_safe_mode never returned.  This leads at least one level deeper due to reset_cpu needing to be a NORETURN function.  Each port is a little different in this area.  I also marked reset_to_bootloader as NORETURN.
Additional notes:

 * stm32's reset_to_bootloader was not implemented, but now does a bare reset.  Most stm32s are not fitted with uf2 bootloaders anyway.
 * ditto cxd56
 * esp32s2 did not implement reset_cpu at all.  I used esp_restart().  (not tested)
 * litex did not implement reset_cpu at all.  I used reboot_ctrl_write.  But notably this is what reset_to_bootloader already did, so one or the other must be incorrect (not tested).  reboot_ctrl_write cannot be declared NORETURN, as it returns unless the special value 0xac is written), so a new unreachable forever-loop is added.
 * cxd56's reset is via a boardctl() call which can't generically be declared NORETURN, so a new unreacahble "for(;;)" forever-loop is added.
 * In several places, NVIC_SystemReset is redeclared with NORETURN applied.  This is accepted just fine by gcc.  I chose this as preferable to editing the multiple copies of CMSIS headers where it is normally declared.
 * the stub safe_mode reset simply aborts.  This is used in mpy-cross.

Split pulseio.PWMOut into pwmio
This gives us better granularity when implementing new ports because
PWMOut is commonly implemented before PulseIn and PulseOut.

Fixes #3211

Jeff Epler dddd25a776 Combine similar strings to reduce size of translations
This is a slight trade-off with code size, in places where a "_varg"
mp_raise variant is now used.  The net savings on trinket_m0 is
just 32 bytes.

It also means that the translation will include the original English
text, and cannot be translated.  These are usually names of Python
types such as int, set, or dict or special values such as "inf" or
"Nan".

Jeff Epler f232aef786 supervisor.mk: Compute USB_DEVICES; remove from boards and ports
Since Actions passed on the previous commit, where this computed value
was checked against the specified value (if any), this is no net change,
except that we no longer need to specify it for particular boards or
ports.

Jeff Epler a580f0f1c4 _pew: move to common-hal
I noticed that this code was referring to samd-specific functionality,
and isn't enabled except in one samd board (pewpew10).  Move it.

There is incomplte support for _pew in mimxrt10xx which then caused build
errors; adding a #if guard to check for _pew being enabled fixes it.
The _pew module is not likely to be important on mimxrt but I'll leave the
choice to remove it to someone else.
