bbccb0f630 esp8266: Remove scanning of GC pointers in native code block.
The native code no longer holds live GC pointers so doesn't need to be
scanned.

da2d2b6d88 py/mpconfig.h: Introduce MICROPY_DEBUG_PRINTER for debugging output.
This patch in effect renames MICROPY_DEBUG_PRINTER_DEST to
MICROPY_DEBUG_PRINTER, moving its default definition from
lib/utils/printf.c to py/mpconfig.h to make it official and documented, and
makes this macro a pointer rather than the actual mp_print_t struct.  This
is done to get consistency with MICROPY_ERROR_PRINTER, and provide this
macro for use outside just lib/utils/printf.c.

Ports are updated to use the new macro name.

c3c914f4dd esp8266,esp32: Implement high-res timers using new tick_hz argument.
machine.Timer now takes a new argument in its constructor (or init method):
tick_hz which specified the units for the period argument.  The period of
the timer in seconds is: period/tick_hz.

For backwards compatibility tick_hz defaults to 1000.  If the user wants to
specify the period (numerator) in microseconds then tick_hz can be set to
1000000.  The user can also specify a period of an arbitrary number of
cycles of an arbitrary frequency using these two arguments.

An additional freq argument has been added to allow frequencies to be
specified directly in Hertz.  This supports floating point values when
available.

bccf9d3dcf esp8266: Let machine.WDT trigger the software WDT if obj is not fed.
This patch allows scripts to have more control over the software WDT.  If
an instance of machine.WDT is created then the underlying OS is prevented
from feeding the software WDT, and it is up to the user script to feed it
instead via WDT.feed().  The timeout for this WDT is currently fixed and
will be between 1.6 and 3.2 seconds.

b6e5f82ba5 esp8266/modesp: Run ets_loop_iter before/after doing flash erase/write.
A flash erase/write takes a while and during that time tasks may be
scheduled via an IRQ.  To prevent overflow of the task queue (and loss of
tasks) call ets_loop_iter() before and after slow flash operations.

Note: if a task is posted to a full queue while a flash operation is in
progress then this leads to a fault when trying to print out the error
message that the queue is full.  This patch doesn't try to fix this
particular issue, it just prevents it from happening in the first place.

d800ed1877 esp8266/esp8266_common.ld: Put mp_keyboard_interrupt in iRAM.
This function may be called from a UART IRQ, which may interrupt the system
when it is erasing/reading/writing flash.  In such a case all code
executing from the IRQ must be in iRAM (because the SPI flash is busy), so
put mp_keyboard_interrupt in iRAM so ctrl-C can be caught during flash
access.

This patch also takes get_fattime out of iRAM and puts it in iROM to make
space for mp_keyboard_interrupt.  There's no real need to have get_fattime
in iRAM because it calls other functions in iROM.

Fixes issue #3897.

afd0701bf7 esp8266: Change UART(0) to attach to REPL via uos.dupterm interface.
This patch makes it so that UART(0) can by dynamically attached to and
detached from the REPL by using the uos.dupterm function.  Since WebREPL
uses dupterm slot 0 the UART uses dupterm slot 1 (a slot which is newly
introduced by this patch).  UART(0) must now be attached manually in
boot.py (or otherwise) and inisetup.py is changed to provide code to do
this.  For example, to attach use:

    import uos, machine
    uart = machine.UART(0, 115200)
    uos.dupterm(uart, 1)

and to detach use:

    uos.dupterm(None, 1)

When attached, all incoming chars on UART(0) go straight to stdin so
uart.read() will always return None.  Use sys.stdin.read() if it's needed
to read characters from the UART(0) while it's also used for the REPL (or
detach, read, then reattach).  When detached the UART(0) can be used for
other purposes.

If there are no objects in any of the dupterm slots when the REPL is
started (on hard or soft reset) then UART(0) is automatically attached.
Without this, the only way to recover a board without a REPL would be to
completely erase and reflash (which would install the default boot.py which
attaches the REPL).

6410e174c5 esp8266: Disable DEBUG_PRINTERS for 512k build.
Disabling this saves around 6000 bytes of code space and gets the 512k

increase in the size of the ESP8266 SDK).

033c32e694 esp8266/esp_mphal.h: Fix I2C glitching by using input mode for od_high.
Certain pins (eg 4 and 5) seem to behave differently at the hardware level
when in open-drain mode: they glitch when set "high" and drive the pin
active high for a brief period before disabling the output driver.  To work
around this make the pin an input to let it float high.

58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver.
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.

b691aa0aae esp8266/esppwm: Always start timer to avoid glitch from full to nonfull.
The PWM at full value was not considered as an "active" channel so if no
other channel was used the timer used to mange PWM was not started.  So
when another duty value was set the PWM timer restarted and there was a
visible glitch when driving LEDs.  Such a glitch can be seen with the
following code (assuming active-low LED on pin 0):

    p = machine.PWM(machine.Pin(0))
    p.duty(1023) # full width, LED is off
    p.duty(1022) # LED flashes brightly then goes dim

This patch fixes the glitch.

These were copied from the stm32 port (then stmhal) at the very beginning

definition files with a list of valid pins and their names.  But that has
not been implemented and likely won't be, so remove the corresponding lines
from the Makefile.

4601759bf5 py/objstr: Remove "make_qstr_if_not_already" arg from mp_obj_new_str.
This patch simplifies the str creation API to favour the common case of
creating a str object that is not forced to be interned.  To force
interning of a new str the new mp_obj_new_str_via_qstr function is added,
and should only be used if warranted.

Apart from simplifying the mp_obj_new_str function (and making it have the
same signature as mp_obj_new_bytes), this patch also reduces code size by a
bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs).

37282f8fc1 extmod/uos_dupterm: Update uos.dupterm() and helper funcs to have index.
The uos.dupterm() signature and behaviour is updated to reflect the latest
enhancements in the docs.  It has minor backwards incompatibility in that
it no longer accepts zero arguments.

The dupterm_rx helper function is moved from esp8266 to extmod and
generalised to support multiple dupterm slots.

A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM
config macro to an integer, being the number of slots it wants to have;
0 means to disable the dupterm feature altogether.

The unix and esp8266 ports are updated to work with the new interface and
are otherwise unchanged with respect to functionality.

a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.
