Adds a bootloader information sharing system for MCUboot and
|
|
applications which allows applications to read the configuration of
|
|
MCUboot and the running image. This can be used by applications so
|
|
that they know how to e.g. handle firmware updates and place them
|
|
into the correct slot.
|
|
|
|
In order to use this, a retention area must be created and set as
|
|
the "zephyr,bootloader-info" chosen node via device tree, MCUboot
|
|
must be built with the same "zephyr,bootloader-info" DTS node and
|
|
have CONFIG_BOOT_SHARE_DATA, CONFIG_BOOT_SHARE_DATA_BOOTINFO and
|
|
CONFIG_BOOT_SHARE_BACKEND_RETENTION enabled, or the shared
|
|
information will not be accessible.
