On systems that cannot feed the watchdog from an ISR (e.g. anything
without a button) then tab completion is risky because the watchdog might
fire before all the options are listed. Fix this by feeding the dog from
the tx routine.

A soft reset doesn't reconfigure the watchdog which means if previous
software on the device has set a bad timeout then we are stuck without
until the battery runs flat or a watchdog reset takes place. Add a
mechanism to stop feeding the dog so that we can wait for it to trigger.

This is mostly use for BLE comms since it allows us to easily share
data structures with our peers.

This allows us to load .mpy files stored in the filesystem without having
to invoke the compiler (e.g. with a much lower memory overhead).

Currently pinetime reserves 64k of FLASH for an unused file system. This
is pointless because we have a 4MB SPI flash that we can use as a
filesystem.
It is also pointless on dsd6 and nitrogen because we'd prefer to run
without a filesystem than to have something so stunted!

These 32 bytes can be used as pseudo-NVRAM to allow communication between
the payload and the bootloader. The pseudo-NVRAM driver can be written in
pure python (using machine.mem32) so there no code changes beyond reserving
the memory are required.
Currently the nrf port doesn't implement a proper RTC (it exposes
raw RTCounters instead) but it is still useful to implement
localtime() and mktime() (although the argument to localtime becomes
mandatory).
Feeding a watchdog from a periodic interrupt isn't the smartest thing
to do (unless you have setup multi-channels) so we also allow us to
express to the WDT driver whether we've arrived from an ISR or not.
Currently it is difficult to deploy uPy on form factor devices without
a reset pin. Any mistake in the boot code risks the system getting
stuck (at least until the battery goes flat). A watchdog and user
button can be combined to give a long-press reset that gives the user
a better shot at recovering the device before the battery runs down!
Move webrepl support code from ports/esp8266/modules into extmod/webrepl
(to be alongside extmod/modwebrepl.c), and use frozen manifests to include
it in the build on esp8266 and esp32.
A small modification is made to webrepl.py to make it work on non-ESP
ports, i.e. don't call dupterm_notify if not available.
- Corrected pin assignments and checked with CubeMX.
- Added additional I2C and UARTs.
- Added Ethernet interface definitions with lwIP and SSL support (but
Ethernet is currently unsupported on H7 MCUs so not fully enabled).
- Removed remarks on DFU/OCD in mpconfigboard.h because deploy-stlink works
fine too.
- Added more UARTs, I2C, corrected SPI, CAN, etc; verified against CubeMX.
- Adapted pins.csv to remove errors, add omissions, etc. according to
NUCLEO-144 User Manual.
- Changed linker file stm32f767.ld to reflect correct size of the Flash.
- Tested with LAN and SD card.
The Nucleo board does not have an SD card slot but does have the requisite
pins next to each other and labelled, so provide the configuration for
convenience.
