|
|
Adds a boot mode system that allows for changing execution flow
|
|
depending upon the value of a boot mode parameter. Can be used for
|
|
e.g. button-less bootloader serial recovery mode entering from the
|
|
application.
|
|
|
|
In order to use this, a retention area with at least 1 usable user
|
|
byte must be created and set as the "zephyr,boot-mode" chosen node
|
|
via device tree.
