boot: zephyr: socs: stm32h7s7xx: Add support for ext_flash_app variant

On the same example as stm23h750xx and stm32h573xx, introduce
ext_flash_app variant for stm32h7s7xx in mcuboot.

This allows chainloading applications in ext flash from a mcuboot
application running in internal flash.

Similarly, BOOT_MAX_IMG_SECTORS_AUTO is no longer needed to be disabled
after including the 'soc-nv-flash' binding in the 'st,stm32-xspi-nor'
binding, whihc provides 'erase-block-size' and 'write-block-size' to
external Flash DT node.

Remove the no longer required Kconfig fragment for stm32h7s78_dk.

MCUboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Build Status (Espressif) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is MCUboot version 2.3.0-dev

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a common infrastructure for the bootloader and the system flash layout on microcontroller systems, and provides a secure bootloader that enables easy software upgrade.

MCUboot is not dependent on any specific operating system and hardware and relies on hardware porting layers from the operating system it works with. Currently, MCUboot works with the following operating systems and SoCs:

RIOT is supported only as a boot target. We will accept any new port contributed by the community once it is good enough.

MCUboot How-tos

See the following pages for instructions on using MCUboot with different operating systems and SoCs:

There are also instructions for the Simulator.

Roadmap

The issues being planned and worked on are tracked using GitHub issues. To give your input, visit MCUboot GitHub Issues.
