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.

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.

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

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.

Damien George 3eff81288c stm32/i2c: Fix generation of restart condition for hw I2C on F0/F7.
Before this patch I2C transactions using a hardware I2C peripheral on F0/F7
MCUs would not correctly generate the I2C restart condition, and instead
would generate a stop followed by a start.  This is because the CR2 AUTOEND
bit was being set before CR2 START when the peripheral already had the I2C
bus from a previous transaction that did not generate a stop.

As a consequence all combined transactions, eg read-then-write for an I2C
memory transfer, generated a stop condition after the first transaction and
didn't generate a stop at the very end (but still released the bus).  Some
I2C devices require a repeated start to function correctly.

This patch fixes this by making sure the CR2 AUTOEND bit is set after the
start condition and slave address have been fully transferred out.

The previous version did not work on MCUs that only had USB device mode
(compared to OTG) because of the handling of NAK.  And this previous
handling of NAK had a race condition where a new packet could come in
before USBD_HID_SetNAK was called (since USBD_HID_ReceivePacket clears NAK
as part of its operation).  Furthermore, the double buffering of incoming
reports was not working, only one buffer could be used at a time.

This commit rewrites the HID interface code to have a single incoming
buffer, and only calls USBD_HID_ReceivePacket after the user has read the
incoming report (similar to how the VCP does its flow control).  As such,
USBD_HID_SetNAK and USBD_HID_ClearNAK are no longer needed.

API functionality from the user's point of view should be unchanged with
this commit.

Damien George fd49fcb229 stm32/gccollect: Always use MP_STATE_THREAD(stack_top) to get stack top.
In a non-thread build, using &_ram_end as the top-of-stack is no longer
correct because the stack is not always at the very top end of RAM.  See
eg 04c7cdb668 and
3786592097.  The correct value to use is
&_estack, which is the value stored in MP_STATE_THREAD(stack_top), and
using the same code for both thread and non-thread builds makes the code
cleaner.

stm32lib now provides system_stm32XXxx.c source files for all MCU variants,
which includes SystemInit and prescaler tables.  Since these are quite
standard and don't need to be changed, switch to use them instead of custom
variants, making the start-up code cleaner.

Damien George 8da39fd182 stm32/qspi: Use MPU to allow access to valid memory-mapped QSPI region.
The Cortex-M7 CPU will do speculative loads from any memory location that
is not explicitly forbidden.  This includes the QSPI memory-mapped region
starting at 0x90000000 and with size 256MiB.  Speculative loads to this
QSPI region may 1) interfere with the QSPI peripheral registers (eg the
address register) if the QSPI is not in memory-mapped mode; 2) attempt to
access data outside the configured size of the QSPI flash when it is in
memory-mapped mode.  Both of these scenarios will lead to issues with the
QSPI peripheral (eg Cortex bus lock up in scenario 2).

To prevent such speculative loads from interfering with the peripheral the
MPU is configured in this commit to restrict access to the QSPI mapped
region: when not memory mapped the entire region is forbidden; when memory
mapped only accesses to the valid flash size are permitted.

Chris Mason 3786592097 stm32/boards: Optimise flash and RAM allocation for L4 boards.
Optimisations are:
- Remove FLASH_ISR section since devices with a small flash sector erase
  size don't need special FLASH_ISR handling.  This reduces flash image by
  approx 1.5k.
- Make SRAM2 contiguous with SRAM1 where possible.
- Simplify configuration of 2k RAM buffer used for flash filesystem.

RAM changes with this commit:
- L432: stack   6k -> 10k,  bss + heap   42k ->  52k
- L476: stack  16k -> 30k,  bss + heap   80k ->  96k
- L496: stack 206k -> 16k,  bss + heap  112k -> 302k
