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.

9bcdb0acd1 esp8266/Makefile: Remove commented-out unused lines.
These were copied from the stm32 port (then stmhal) at the very beginning
of this port, with the anticipation that the esp8266 port would have board
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.

badaf3ecfe esp8266/machine_hspi: After an SPI write wait for last byte to transfer.
Because otherwise the function can return with data still waiting to be
clocked out, and CS might then be disabled before the SPI transaction is
complete.  Fixes issue #3487.

4e056d82cc esp8266/modules/webrepl_setup: Fix first-time enable of WebREPL.
Prior to this fix, enabling WebREPL for the first time via webrepl_setup
did not work at all because "boot.py" did not contain any lines with
"webrepl" in them that could be uncommented.

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).

964bf935a3 esp8266/esp8266_common.ld: Put .text of more libs into .irom0.text .
Recent vendor SDKs ship libs with code in .text section, which previously
was going into .irom0.text. Adjust the linker script to route these
sections back to iROM (follows upstream change).

1b146e9de9 py/mpconfig: Introduce reusable MP_HTOBE32(), etc. macros.
Macros to convert big-endian values to host byte order and vice-versa.
These were defined in adhoc way for some ports (e.g. esp8266), allow
reuse, provide default implementations, while allow ports to override.

e766a4af4a esp8266/etshal.h: Make function prototypes compatible with ESP SDK 2.1.0+.
In the vendor SDK 2.1.0, some of the functions which previously didn't
have prototypes, finally acquired them. Change prototypes on our side
to match those in vendor headers, to avoid warnings-as-errors.

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.

9b4666dad5 esp8266/posix_helpers: Set ENOMEM on memory alloc failure.
POSIX requires malloc(), etc. to set ENOMEM on the failure, and e.g.
BerkeleyDB relies on this:

http://pubs.opengroup.org/onlinepubs/9699919799/functions/malloc.html

This should fix confusing OSError exceptions with 0 error code when
working with btree module.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.

in a sustainable way.
