Jim Mussared fbb7646e3b stm32/nimble_hci_uart.c: Prevent scheduler running during CYW-BT wakeup.
Using mp_hal_delay_ms allows the scheduler to run, which might result in
another transmit operation happening, which would bypass the sleep (and
fail).  Use mp_hal_delay_us instead.

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 c13f9f209d all: Convert nlr_raise(mp_obj_new_exception_msg(x)) to mp_raise_msg(x).
This helper function was added a while ago and these are the remaining
cases to convert, to save a bit of code size.

Damien George 48b25a841b stm32: Add machine.Timer with soft timer implementation.
This commit adds an implementation of machine.Timer backed by the soft
timer mechanism.  It allows an arbitrary number of timers with 1ms
resolution, with an associated Python callback.  The Python-level API
matches existing ports that have a soft timer, and is used as:

    from machine import Timer
    t = Timer(freq=10, callback=lambda t:print(t))
    ...
    t = Timer(mode=Timer.ONE_SHOT, period=2000, callback=lambda t:print(t))
    ...
    t.deinit()

Damien George a5d97f1db9 stm32: Add soft timer implementation, using SysTick at 1ms resolution.
This commit adds an implementation of a "software timer" with a 1ms
resolution, using SysTick.  It allows unlimited number of concurrent
timers (limited only by memory needed for each timer entry).  They can be
one-shot or periodic, and associated with a Python callback.

There is a very small overhead added to the SysTick IRQ, which could be
further optimised in the future, eg by patching SysTick_Handler code
dynamically.

Jim Mussared b02d7e612d extmod/modbluetooth: Rename module to "ubluetooth".
For consistency with "umachine". Now that weak links are enabled
by default for built-in modules, this should be a no-op, but allows
extension of the bluetooth module by user code.

Also move registration of ubluetooth to objmodule rather than
port-specific.

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.

Damien George 12413e92a3 stm32/powerctrlboot: Fix config of systick IRQ priority on F0/L0/WB MCU.
Prior to this commit the systick IRQ priority was set at lowest priority on
F0/L0/WB MCUs, because it was left at the default and never configured.
This commit ensures the priority is configured and sets it to the highest
priority.

Jim Mussared 902bb4ceae stm32: Extract port-specific Nimble implementation.
On other ports (e.g. ESP32) they provide a complete Nimble implementation
(i.e. we don't need to use the code in extmod/nimble). This change
extracts out the bits that we don't need to use in other ports:
 - malloc/free/realloc for Nimble memory.
 - pendsv poll handler
 - depowering the cywbt

Also cleans up the root pointer management.

Chris Mason 0096041c99 stm32/{adc,machine_adc}: Change ADC clock and sampling time for F0 MCUs.
STM32F0 has PCLK=48MHz and maximum ADC clock is 14MHz so use PCLK/4=12MHz
to stay within spec of the ADC peripheral.  In pyb.ADC set common sampling
time to approx 4uS for internal and external sources.  In machine.ADC
reduce sample time to approx 1uS for external source, leave internal at
maximum sampling time.

Damien George 26e90a0514 stm32/boards: Enable MICROPY_HW_RTC_USE_LSE on L4 boards.

hahmadi 266146ad64 stm32/system_stm32: Support selection of HSE and LSI on L4 MCUs.
This commit adds the option to use HSE or MSI system clock, and LSE or LSI
RTC clock, on L4 MCUs.

Note that prior to this commit the default clocks on an L4 part were MSI
and LSE.  The defaults are now MSI and LSI.

In mpconfigboard.h select the clock source via:

    #define MICROPY_HW_RTC_USE_LSE (0) or (1)
    #define MICROPY_HW_CLK_USE_HSE (0) or (1)

and the PLLSAI1 N,P,Q,R settings:

    #define MICROPY_HW_CLK_PLLSAIN (12)
    #define MICROPY_HW_CLK_PLLSAIP (RCC_PLLP_DIV7)
    #define MICROPY_HW_CLK_PLLSAIQ (RCC_PLLQ_DIV2)

For use with F0 MCUs that don't have HSI48.  Select the clock source

On the NUCLEO_F091RC board use HSE bypass when HSE is chosen because the
NUCLEO clock source is STLINK not a crystal.

Chris Mason f16e4be3fa stm32/powerctrlboot: Fix clock and PLL selection for HSI48 on F0 MCUs.
Before this patch the UART baudrate on F0 MCUs was wrong because the
stm32lib SystemCoreClockUpdate sets SystemCoreClock to 8MHz instead of
48MHz if HSI48 is routed directly to SYSCLK.

The workaround is to use HSI48 -> PREDIV (/2) -> PLL (*2) -> SYSCLK.
