Jeff Epler 82be75adb5 Add ability to reserve psram
.. the primary user of which will be the camera, since the framebuffers
must be allocated via esp-idf allocation function and never from the
gc heap.

A board can have a default value, and the value can also be set in the
/.env file using the key CIRCUITPY_RESERVED_PSRAM with the value being
the reserved size in bytes.

Create first BLE-only board, Micro:Bit v2
This fixes build issues with USB off, tweaks the README to allow
for BLE-only boards and adds the Micro:Bit v2 definition.

Fixes #4546

Artyom Skrobov 9a5fb44c76 `workflow_active` was never defined or used
`supervisor_workflow_active` needs to be stubbed for when there's no USB

Artyom Skrobov 4e3c1d4a4c [build] Allow USB to be set to 0
Unify USB-related makefile var and C def as CIRCUITPY_USB.

Always define it as 0 or 1, same as all other settings.

USB_AVAILABLE was conditionally defined in supervisor.mk,
but never actually used to #ifdef USB-related code.

Loosely related to #4546

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.

This can be enforced by pre-commit, but correct it separately to make it easier to review.

Scott Shawcroft 4aeef100f6 atmel-samd: More USB polish
* Introduce a python script to generate the USB descriptor instead of
  a bunch of C macros. In the future, we can use this dynamically in
  CircuitPython.
* Add support for detecting read-only mass storage mounts.

Fixes #377

Scott Shawcroft 6839fff313 Move to ASF4 and introduce SAMD51 support. (#258)
* atmel-samd: Remove ASF3. This will break builds.

* atmel-samd: Add ASF4 for the SAMD21 and SAMD51.

* Introduce the supervisor concept to facilitate porting.

The supervisor is the code which runs individual MicroPython VMs. By
splitting it out we make it more consistent and easier to find.

This also adds very basic SAMD21 and SAMD51 support using the
supervisor. Only the REPL currently works.

This begins the work for #178.
