Jim Mussared 580a2656d1 stm32: Use hardware double sqrt on F7/H7 MCUs.
Identical to cd527bb324 but for doubles.
This gives a -2.754% improvement on bm_float.py, and -35% improvement on
calling sqrt in a loop.

Andrey Belykh 305f537bf9 stm32/sdcard: Support boards with no SD card detect pin.
If MICROPY_HW_SDCARD_DETECT_PIN is not defined then the SD card will always
be detected as present.

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.

Damien George 4a6974bea5 stm32/boards/PYBD_SF2: Put nimble library in external QSPI XIP flash.
The BLE stack is not performance critical, so put it in external
memory-mapped flash to save internal flash for other things (like frozen
bytecode).

Martin Fischer a0ce01f62e stm32/usbdev: Fix compile error if MICROPY_HW_USB_CDC_NUM is set to 2.

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.
The previous commit changed the default configuration on L4 MCUs to use
LSI, so configure these boards to use LSE again.

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)
    #define MICROPY_HW_CLK_PLLSAIR (RCC_PLLR_DIV2)

Chris Mason eb12fa3862 stm32/powerctrlboot: Add support for HSI at 8MHz on F0 MCUs.
For use with F0 MCUs that don't have HSI48.  Select the clock source
explicitly in mpconfigboard.h.

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.

Fixes issue #5049.

iabdalkader f7a07b3605 stm32: Add support for FDCAN peripheral, exposed as pyb.CAN.
The new fdcan.c file provides the low-level C interface to the FDCAN
peripheral, and pyb_can.c is updated to support both traditional CAN and
FDCAN, depending on the MCU being compiled for.

Damien George b0e17bbb9d stm32/lwip_inc: Allocate additional MEMP_SYS_TIMEOUT when mDNS enabled.

Chris Wilson a605b53702 stm32/mboot: Support boards with only two LEDs.
Mboot currently requires at least three LEDs to display each of the four
states.  However, since there are only four possible states, the states can
be displayed via binary counting on only 2 LEDs (if only 2 are available).
The existing patterns are still used for 3 or 4 LEDs.

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.
