8c214ed200 stm32: Extended flash filesystem space to 512K on H743 boards.
The H743 has equal sized pages of 128k, which means the filesystem doesn't
need to be near the beginning.  This commit moves the filesystem to the
very end of flash, and extends it to 512k (4 pages).

6936f410ab stm32/storage: Make extended-block-device more configurable.
A board can now define the following to fully customise the extended block
device interface provided by the storage sub-system:
- MICROPY_HW_BDEV_BLOCKSIZE_EXT
- MICROPY_HW_BDEV_READBLOCKS_EXT
- MICROPY_HW_BDEV_WRITEBLOCKS_EXT
- MICROPY_HW_BDEV_ERASEBLOCKS_EXT

40006813c3 stm32/flash: Update flash_get_sector_info to return -1 on invalid addr.
So the caller can tell when an invalid address is used and can take
appropriate action.

c169094f61 stm32/storage: Make pyb.Flash configurable, and support ext block proto.
The pyb.Flash() class can now be used to construct objects which reference
sections of the flash storage, starting at a certain offset and going for a
certain length.  Such objects also support the extended block protocol.
The signature for the constructor is: pyb.Flash(start=-1, len=-1).

59b7166d87 stm32: Add initial support for STM32WBxx MCUs.
This new series of MCUs is similar to the L4 series with an additional
Cortex-M0 coprocessor.  The firmware for the wireless stack must be managed
separately and MicroPython does not currently interface to it.  Supported
features so far include: RTC, UART, USB, internal flash filesystem.

1b956ec817 stm32: Add support for F413 MCUs.
Includes:
- Support for CAN3.
- Support for UART9 and UART10.
- stm32f413xg.ld and stm32f413xh.ld linker scripts.
- stm32f413_af.csv alternate function mapping.
- startup_stm32f413xx.s because F413 has different interrupt vector table.
- Memory configuration with: 240K filesystem, 240K heap, 16K stack.

17f7c683d2 stm32: Add support for STM32F765xx MCUs.
This part is functionally similar to STM32F767xx (they share a datasheet)
so support is generally comparable.  When adding board support the
stm32f767_af.csv and stm32f767.ld should be used.

0941a467e7 stm32: Change flash IRQ priority from 2 to 6 to prevent preemption.
The flash-IRQ handler is used to flush the storage cache, ie write
outstanding block data from RAM to flash.  This is triggered by a timeout,
or by a direct call to flush all storage caches.

Prior to this commit, a timeout could trigger the cache flushing to occur
during the execution of a read/write to external SPI flash storage.  In
such a case the storage subsystem would break down.

SPI storage transfers are already protected against USB IRQs, so by
changing the priority of the flash IRQ to that of the USB IRQ (what is
done in this commit) the SPI transfers can be protected against any
timeouts triggering a cache flush (the cache flush would be postponed until
after the transfer finished, but note that in the case of SPI writes the
timeout is rescheduled after the transfer finishes).

The handling of internal flash sync'ing needs to be changed to directly
call flash_bdev_irq_handler() sync may be called with the IRQ priority
already raised (eg when called from a USB MSC IRQ handler).

a8736e5c36 stm32/flashbdev: Fix bug with L4 block cache, dereferencing block size.
The code was dereferencing 0x800 and loading a value from there, trying to
use a literal value (not address) defined in the linker script
(_ram_fs_cache_block_size) which was 0x800.

a6009a9e35 stm32/*bdev.c: Eliminate dependency on sys_tick_has_passed.
Explicitly writing out the implementation of sys_tick_has_passed makes
these bdev files independent of systick.c and more reusable as a general
component.  It also reduces the code size slightly.

The irq.h header is added to spibdev.c because it uses declarations in that
file (irq.h is usually included implicitly via mphalport.h but not always).

626d6c9756 stm32/storage: Introduce MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE cfg.
This config variable controls whether to support storage on the internal
flash of the MCU.  It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.

1e4caf0b1e stm32/storage: Merge all misc block-dev funcs into a single ioctl func.
It makes it cleaner, and simpler to support multiple different block
devices.  It also allows to easily extend a given block device with new
ioctl operations.

fa13e0d35b stm32: Factor out flash and SPI block-device code to separate files.
Prior to this patch, storage.c was a combination of code that handled
either internal flash or external SPI flash and exposed one of them as a
block device for the local storage.  It was also exposed to the USB MSC.

This patch splits out the flash and SPI code to separate files, which each
provide a general block-device interface (at the C level).  Then storage.c
just picks one of them to use as the local storage medium.  The aim of this
factoring is to allow to add new block devices in the future and allow for
easier configurability.
