* esp32: Reinstate tmr.now() function using esp_timer_get_time()
Also added larger limit before wrapping if Lua's number type supports
it.
* Renamed tmr.now() to node.uptime()
Added second return value to indicate timer wrap
This fixes the panic-on-restart issue and the crash-on-uart-input-before-flash-mapped issue.
Node module updated to reflect new function names for sleep/restart.
node.dsleep() no longer takes options.
node.output() not yet supported (needs syscall registration/chaining support)
Dynamic CPU frequency changing not currently supported in the IDF.
Various chip IDs not currently available/obtainable.
Boot reason completely revamped in ESP32, will need new code.
RTOS driver evicted as it did not play nice with stdio etc.
Implemented a minimal driver to fully support Lua console on UART0. Output
on UART0 done via stdout (provided by the IDF). Input and setup handled
via driver_console/console.c. In addition to the direct input function
console_getc(), the driver also registers in the syscall tables to enable
regular stdio input functions to work (yay!). The Lua VM is still using the
direct interface since it's less overhead, but does also work when going
through stdin/fd 0.
Auto-bauding on the console is not yet functional; revisit when the UART docs
are available.
Module registration/linking/enabling moved over to be Kconfig based. See
updates to base_nodemcu/include/module.h and base_nodemcu/Kconfig for
details.
The sdk-overrides directory/approach is no longer used. The IDF is simply
too different to the old RTOS SDK - we need to adapt our code directly instead.
Everything in app/ is now unused, and will need to be gradually migrated
into components/ though it is probably better to migrate straight from the
latest dev branch.
