8dcce92606 esp8266/scripts: Don't try to create filesystem on 512KB devices or less.

7d2c685544 esp8266/scripts/_boot: Mount block device on "" instead of "/". 
"" is the correct name of the root directory when mounting a device there
(as opposed to "/").  One can now do os.listdir('/') and open('/abc'), as
well as os.listdir() and open('abc').

df3b1741b6 esp8266: Separate 1-wire timing funcs from Python module to save iRAM. 
esponewire.c contains low-level timing-critical functions that go in

0a2e9650f5 py: Add ability to have frozen persistent bytecode from .mpy files. 
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY.  This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).

19e3c9d53a esp8266/esp_mphal: Don't swallow exceptions in dupterm's read()/write(). 
The idea is that if dupterm object can handle exceptions, it will handle
them itself. Otherwise, object state can be compromised and it's better
to terminate dupterm session. For example, disconnected socket will keep
throwing exceptions and dump messages about that.

3177ef544f esp8266: In callback helpers, pop nlr_buf on successful call. 
nlr_pop must be called if no exception was raised.

Also, return value of these callback helpers is made void because ther
is (currently) no use for it.

40f5ecd3a8 esp8266: Add Python modules for initial configuration. 
Main entry point is _boot.py which checks whether FAT FS in flash mountable,
and if so, mounts it. Otherwise, it checks if flash is empty, and if so,
performs initial module setup: makes FAT FS, configures default AP name,
etc. As a last option, if flash is not empty, and could not be mounted,
it means filesystem corruption, and warning message with instructions is
printed in an infinite loop.

6e87aeb841 esp8266: Implement multistage bootstrap sequence. 
Upon start-up, _boot module is executed from frozen files to do early
initialization, e.g. create and mount the flash filesystem. Then
"boot.py" is executed if it exists in the filesystem. Finally, "main.py"
is executed if exists to allow start-on-boot user applications.

This allows a user to make a custom boot file or startup application
without recompiling the firmware, while letting to do early initialization
in Python code.

Based on RFC https://github.com/micropython/micropython/issues/1955.

8d2bcaf3cd esp8266: Minimize gap between Inst/DataRAM segments and FlashROM segment. 
With .rodata being in FlashROM now, gap can be much smaller now. InstRAM
can be max 32K, and with segment headers, that already makes it more than
32K. Then there's some .data still, and the next Flash page boundary is
0x9000. That figure should be more or less future-proof.

fb6cc96951 esp8266/uart: Comment out old, unused rx buffering code. 
This was originally used for non-event based REPL processing.  Then it
was unused when event-based processing was activated.  But now that event
based is disabled, and non-event based is back, there has been new ring
buffer code to process the chars.

785cf9a61f esp8266: Support dedicated REPL loop (aka pull-style). 
Event-driven loop (push-style) is still supported and default (controlled
by MICROPY_REPL_EVENT_DRIVEN setting, as expected).

Dedicated loop worked even without adding ets_loop_iter(), though that
needs to be revisited later.

777232c9a5 esp8266: Disallow recursive calls to REPL. 
Before this change, if REPL blocked executing some code, it was possible
to still input new statememts and excuting them, all leading to weird,
and portentially dangerous interaction.

while REPL was blocked.

4b597a1c1a esp8266: Reset term_obj on reboot. 
Also, term_obj can be NULL if socket enables REPL duplication signalling

Paul Sokolovsky
98af891610 esp8266: Implement input part of dupterm handling. 
The idea is following: underlying interrupt-driven or push-style data source
signals that more data is available for dupterm processing via call to
mp_hal_signal_dupterm_input(). This triggers a task which pumps data between
actual dupterm object (which may perform additional processing on data from
low-level data source) and input ring buffer.

Paul Sokolovsky
61fa7c8152 esp8266: Switch back to accumulating input data via ring buffer. 
But now it's generic ring buffer implemented via ringbuf.h, and is intended
for any type of input, including dupterm's, not just UART. The general
process work like this: an interrupt-driven input source puts data into
input_buf, and then signals new data available via call to
mp_hal_signal_input().

632d8efa05 esp8266: Add PWM support. 
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.

8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.

Usage:

    import machine
    pwm0 = machine.PWM(machine.Pin(0))
    pwm0.freq(1000)
    pwm0.duty(500)

Frequency is shared (ie the same) for all channels.  Frequency is
between 1 and 1000.  Duty is between 0 and 1023.
