Olivier Ortigues 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.

Rafael Römhild 8f3167a962 esp8266/boards: Allow configuring btree/FAT/LFS2 support when building.
Prior to e0905e85a7 it was possible to
disable btree support on build.  This patch allows to configure btree
support on make again and also the two new introduced options for FAT and
LFS2 filesystems.

Damien George 67fca2b715 esp8266/uart: Move a few functions from iRAM to iROM.
They call functions in iROM so do not need to be in iRAM.

Damien George f2218c2fbd esp8266/esp_mphal: Move most functions in esp_mphal.c from iRAM to iROM.
The ones that are moved out of iRAM should not need to be there, because
either they call functions in iROM (eg mp_hal_stdout_tx_str), or they are
only ever called from a function in iROM and not from an interrupt (eg
ets_esf_free_bufs).

This frees up about 800 bytes of iRAM.

Damien George e12de1fd9d esp8266: Clean up Pin intr handler by moving all code to machine_pin.c.
The macro MP_FASTCODE is used to explicitly place required functions in

Damien George 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.

Damien George 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.

Damien George 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.

This string is recognised by uncrustify, to disable formatting in the
region marked by these comments.  This is necessary in the qstrdef*.h files
to prevent modification of the strings within the Q(...).  In other places
it is used to prevent excessive reformatting that would make the code less
readable.

Damien George ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate.
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size

Damien George 8d0421c3cf esp8266: Put mp_keyboard_interrupt in IRAM.
It was originally in IRAM due to the linker script specification, but
since the function moved from lib/utils/interrupt_char.c to py/scheduler.c
it needs to be put back in IRAM.

JensDiemer c14ff6194c esp8266/modules: Fix AttributeError in _boot.py if flash not formatted.
Prior to this commit, if the flash filesystem was not formatted then it
would error: "AttributeError: 'FlashBdev' object has no attribute 'mount'".
That is due to it not being able to detect the filesystem on the block
device and just trying to mount the block device directly.

This commit fixes the issue by just catching all exceptions.  Also it's not
needed to try the mount if `flashbdev.bdev` is None.

Jim Mussared 7ce1e0b1dc extmod/webrepl: Move webrepl scripts to common place and use manifest.
Move webrepl support code from ports/esp8266/modules into extmod/webrepl
(to be alongside extmod/modwebrepl.c), and use frozen manifests to include
it in the build on esp8266 and esp32.

A small modification is made to webrepl.py to make it work on non-ESP
ports, i.e. don't call dupterm_notify if not available.

Damien George 799b6d1e0c extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it.  It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.

For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile.  This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.

Damien George d2384efa80 py: Automatically provide weak links from "foo" to "ufoo" module name.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found.  This means that all modules named "ufoo" are always
available as "foo".  Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.

It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.

Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
  which saves code size, but will mean that "import foo" creates a new qstr
  (namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
  this reduces duplication in the help listing.

Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last.  So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists.  Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".

See issues: #1740, #4449, #5229, #5241.

Jim Mussared 8ba963cfa3 tools/makemanifest.py: Eval relative paths w.r.t. current manifest file.
When loading a manifest file, e.g. by include(), it will chdir first to the
directory of that manifest.  This means that all file operations within a
manifest are relative to that manifest's location.

As a consequence of this, additional environment variables are needed to
find absolute paths, so the following are added: $(MPY_LIB_DIR),
$(PORT_DIR), $(BOARD_DIR).  And rename $(MPY) to $(MPY_DIR) to be
consistent.

Existing manifests are updated to match.
