9b07d38c7e stm32/mboot: Add support for 64-bit mboot address space for reads.
If enabled via MBOOT_ADDRESS_SPACE_64BIT (it's disabled by default) then
read addresses will be 64-bit.

26faf74d52 stm32/mboot: Add support for F469/479 MCUs in fwupdate.py.
And don't assert on the sector number in sector_erase, so it can support
erasing arbitrary sectors.

c6f334272a stm32/mboot: Add support for signed and encrypted firmware updates.
This commit adds support to stm32's mboot for signe, encrypted and
compressed DFU updates.  It is based on inital work done by Andrew Leech.

The feature is enabled by setting MBOOT_ENABLE_PACKING to 1 in the board's
mpconfigboard.mk file, and by providing a header file in the board folder
(usually called mboot_keys.h) with a set of signing and encryption keys
(which can be generated by mboot_pack_dfu.py).  The signing and encryption
is provided by libhydrogen.  Compression is provided by uzlib.  Enabling
packing costs about 3k of flash.

The included mboot_pack_dfu.py script converts a .dfu file to a .pack.dfu
file which can be subsequently deployed to a board with mboot in packing
mode.  This .pack.dfu file is created as follows:
- the firmware from the original .dfu is split into chunks (so the
  decryption can fit in RAM)
- each chunk is compressed, encrypted, a header added, then signed
- a special final chunk is added with a signature of the entire firmware
- all chunks are concatenated to make the final .pack.dfu file

The .pack.dfu file can be deployed over USB or from the internal filesystem
on the device (if MBOOT_FSLOAD is enabled).

See #5267 and #5309 for additional discussion.

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)
