Commit 0abf6f830c removed _boot.py from the
manifest for the GENERIC_512K board because the build does not include a
filesystem.  But the main code expects _boot.py to be there and prints an
error if it's not.  So add a custom _boot.py, which just sets the

0abf6f830c esp8266/boards/GENERIC_512K: Add custom manifest without FS modules.
The 512k build does not have a filesystem so there is no reason to include
the filesystem-related modules.  This commit provides a custom manifest.py
for this board which no longer includes: _boot.py, flashbdev.py,
inisetup.py, upip.py, upip_utarfile.py.  This cuts the build down by about
9k of flash.

39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

8f20cdc353 all: Rename absolute time-based functions to include "epoch".
For time-based functions that work with absolute time there is the need for
an Epoch, to set the zero-point at which the absolute time starts counting.
Such functions include time.time() and filesystem stat return values.  And
different ports may use a different Epoch.

To make it clearer what functions use the Epoch (whatever it may be), and
make the ports more consistent with their use of the Epoch, this commit
renames all Epoch related functions to include the word "epoch" in their
name (and remove references to "2000").

Along with this rename, the following things have changed:

- mp_hal_time_ns() is now specified to return the number of nanoseconds
  since the Epoch, rather than since 1970 (but since this is an internal
  function it doesn't change anything for the user).

- littlefs timestamps on the esp8266 have been fixed (they were previously
  off by 30 years in nanoseconds).

Otherwise, there is no functional change made by this commit.

b28758054b esp8266: Remove release-specific manifest, disable osdebug by default.
This commit removes release-specific builds for the esp8266 and makes the
normal build of the GENERIC board more like the release build.  This makes
esp8266 like all the other ports, for which there is no difference between
a daily build and a release build, making things less confusing.

Release builds were previously defined by UART_OS=-1 (disable OS messages)
and using manifest_release.py to include more frozen modules.

The changes in this commit are:
- Remove manifest_release.py.
- Add existing modules from manifest_release.py (except example code)
  to the GENERIC board's manifest.py file.
- Change UART_OS default to -1 to disable OS messages by default.

e32302c1a6 esp8266/esppwm: Fix PWM glitch when setting duty on different channel.
The PWM driver uses a double buffer for the PWM timing array, one in
current use and the other one to update when changing duty parameters.
The issue was that once the duty parameters were changed the updated buffer
was applied immediately without synchronising to the start of the PWM
period.  By moving the buffer toggling/swapping to the interrupt when the
cycle is done there are no more glitches.

0bd58a5613 esp8266/machine_pin: Move pin_intr_handler to iRAM, de-support hard IRQ.
GPIO interrupts can occur when the flash ROM cache is in use and so the
GPIO interrupt handler must be in iRAM.  This commit moves the handler to
iRAM, and also moves mp_sched_schedule to iRAM which is called by
pin_intr_handler.

As part of this fix the Pin class can no longer support hard=True in the
Pin.irq() method, because the VM and runtime are too big to put in iRAM.

Fixes #5714.

e08ca78f40 py/stream: Remove mp_stream_errno and use system errno instead.
This change is made for two reasons:

1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system
   provided errno for certain errors, and yet MicroPython stream objects
   that it calls will be using the internal mp_stream_errno.  So if the
   library returns an error it is not known whether the corresponding errno
   code is stored in the system errno or mp_stream_errno.  Using the system
   errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this
   ambiguity.

2. For systems that have threading the system-provided errno should always
   be used because the errno value is thread-local.

For systems that do not have an errno, the new lib/embed/__errno.c file is
provided.

e0905e85a7 esp8266: Change from FAT to littlefs v2 as default filesystem.
This commit changes the esp8266 boards to use littlefs v2 as the
filesystem, rather than FAT.  Since the esp8266 doesn't expose the
filesystem to the PC over USB there's no strong reason to keep it as FAT.
Littlefs is smaller in code size, is more efficient in use of flash to
store data, is resilient over power failure, and using it saves about 4k of
heap RAM, which can now be used for other things.

This is a backwards incompatible change because all existing esp8266 boards
will need to update their filesystem after installing new firmware (eg
backup old files, install firmware, restore files to new filesystem).

As part of this commit the memory layout of the default board (GENERIC) has
changed.  It now allocates all 1M of memory-mapped flash to the firmware,
so the filesystem area starts at the 2M point.  This is done to allow more
frozen bytecode to be stored in the 1M of memory-mapped flash.  This
requires an esp8266 module with 2M or more of flash to work, so a new board
called GENERIC_1M is added which has the old memory-mapping (but still
changed to use littlefs for the filesystem).

In summary there are now 3 esp8266 board definitions:
- GENERIC_512K: for 512k modules, doesn't have a filesystem.
- GENERIC_1M: for 1M modules, 572k for firmware+frozen code, 396k for
  filesystem (littlefs).
- GENERIC: for 2M (or greater) modules, 968k for firmware+frozen code,
  1M+ for filesystem (littlefs), FAT driver also included in firmware for
  use on, eg, external SD cards.
