- Add to docs & config descriptions
- Change to a "choice" to become self-documenting
- Keep the bootloader_common_check_long_hold_gpio() function for compatibility
Add the possibility to have user bootloader components. This is performed
from an application/project, by creating bootloader components. To do so,
it is required to create a `bootloader_component` directory containing
the custom modules to be compiled with the bootloader.
Thanks to this, two solutions are available to override the bootloader now:
- Using hooks within a user bootloader component
- Using a user defined `main` bootloader component to totally override the
old implementation
Please check the two new examples in `examples/custom_bootloader`
* Closes https://github.com/espressif/esp-idf/issues/7043
Additionally, always enable the partition MD5 check if flash encryption is on in
Release mode. This ensures the partition table ciphertext has not been modified
(CVE-2021-27926).
The exception is pre-V3.1 ESP-IDF bootloaders and partition tables, which
don't have support for the MD5 entry.
The build system automatically determines offsets of partitions from
the partition table, so no manual changes are needed. Instead, add a
note that partition offsets may need to be updated when increasing
the bootloader size.
Added feature:
- reset firmware to Factory app.(by long pressing of the button)
- boot Test app. (by long pressing of the button)
- Added feature erase data partitions from factory reset.

Need to make the bootloader modular so that users can redefine its functional part.
- refactoring and moving functions to the bootloader_support component
- Changed function to `void` bootloader_utility_load_image(...);
