e359b077dd ports: Add board.json for all boards.
This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.

Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

8a5bfe44a5 esp32,stm32: Add new machine.I2S class for I2S protocol support.
This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class.  It builds on the stm32 work of blmorris, #1361.

Features include:
- a consistent I2S API across the esp32 and stm32 ports
- I2S configurations supported:
  - master transmit and master receive
  - 16-bit and 32-bit sample sizes
  - mono and stereo formats
  - sampling frequency
  - 3 modes of operation:
    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
  - Pyboard D SF2W
  - Pyboard V1.1
  - ESP32 with SPIRAM
  - ESP32

211c3e41f1 stm32/boards/PYBD_SF2: Disable GCC 11 warnings for array bounds.
With GCC 11 there is now a warning about array bounds of OTP-mac, due to
the OTP being a literal address.

cf7e71fa43 stm32/sdcard: Allow configuring the SDMMC periph used for SD/MMC card.
This can now be selected by setting MICROPY_HW_SDCARD_SDMMC, which defaults
to 1, ie SDMMC1.  This commit also renames the SD pin configuration macros
from MICROPY_HW_SDMMC2_xxx to MICROPY_HW_SDCARD_xxx, as well as renaming
MICROPY_HW_SDMMC_BUS_WIDTH to MICROPY_HW_SDCARD_BUS_WIDTH.

25ae169e6e stm32: Include .ARM section in firmware for C++ exception handling.
Support for C++ was added in 97960dc7de but
that commit didn't include the C++ exception handling table in the binary
firmware image.  This commit fixes that.

e715a8fb9b stm32/boards/PYBD_SF2: Disable SPIFLASH_ENABLE_CACHE for mboot builds.
Mboot builds do not use the external SPI flash in caching mode, and
explicitly disabling it saves RAM and a small bit of flash.

e43a74a4db drivers/memory/spiflash: Add MICROPY_HW_SPIFLASH_ENABLE_CACHE option.
This only needs to be enabled if a board uses FAT FS on external SPI flash.
When disabled (and using external SPI flash) 4k of RAM can be saved.

67fd58bbd2 stm32/mboot: Add support for littlefs.
Mboot now supports FAT, LFS1 and LFS2 filesystems, to load firmware from.
The filesystem needed by the board must be explicitly enabled by the
configuration variables MBOOT_VFS_FAT, MBOOT_VFS_LFS1 and MBOOT_VFS_LFS2.
Boards that previously used FAT implicitly (with MBOOT_FSLOAD enabled) must
now add the following config to mpconfigboard.h:

    #define MBOOT_VFS_FAT (1)

e3187b052f stm32/boards/PYBD: Change RTC asynch prediv from 1 to 4.
This change has the following effects:
- Reduces the resolution of the RTC sub-second counter from 30.52us to
  122.07us.
- Allows RTC.calibration() to now support positive values (as well as
  negative values).
- Reduces VBAT current consumption in standby mode by a small amount.

For general purpose use 122us resolution of the sub-second counter is
good enough, and the benefits of full range calibration and minor reduction
in VBAT consumption are worth the change.

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).

04c7cdb668 stm32: Enter bootloader via a system reset.
Entering a bootloader (ST system bootloader, or custom mboot) from software
by directly branching to it is not reliable, and the reliability of it
working can depend on the peripherals that were enabled by the application
code.  It's also not possible to branch to a bootloader if the WDT is
enabled (unless the bootloader has specific provisions to feed the WDT).

This patch changes the way a bootloader is entered from software by first
doing a complete system reset, then branching to the desired bootloader
early on in the start-up process.  The top two words of RAM (of the stack)
are reserved to store flags indicating that the bootloader should be
entered after a reset.

14cf91f704 stm32: In link script, define start of stack separately from heap end.
Previously the end of the heap was the start (lowest address) of the stack.
With the changes in this commit these addresses are now independent,
allowing a board to place the heap and stack in separate locations.
