Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from partition.
New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.
Routine `spi_flash_cache2phys` sometimes return incorrect value,
resulting in failure in getting currently running ota partition.
This in turn aborts firmware update process.This issue was more
prominent with SPIRAM enabled cases.
Fix ensures proper cache guards during `spi_flash_cache2phys`, and
also for few other similar APIs.
In addition, `esp_ota_get_running_partition` has also been optimized
to save currently running partition for subsequent invocations.
Fixes https://github.com/espressif/esp-idf/issues/2451
Allows OTA updates to be secured via signature checks, without requiring the overhead or complexity
of a full secure boot implementation.
Uses same signing mechanisms (build system and/or espsecure.py as Secure Boot).
Requires:
* [ ] More testing
* [ ] Documentation
Added bootloader_common_get_sha256_of_partition() and esp_partition_get_sha256() - get or calculate SHA-256
digest for app and data partitions.
Added bootloader_sha256_hex_to_str() - helps to print SHA-256 digest
Added esp_partition_check_identity() - compares two partitions by SHA-256 digest
Refactoring a function esp_image_load() in bootloader space to esp_image_verify() and
bootloader_load_image(). Old name function esp_image_load is deprecated
and will remove in V4.0 version.
spi_flash/sim: Fix error test_host. Add stub for bootloader_common_get_sha256_of_partition in sim/stubs
Add a command `make erase_ota` - erases otadata if it there is in the
partition table otherwise error 'Partition table does not have ota_data partition'.
Closes https://github.com/espressif/esp-idf/issues/1821
in the include file esp_ota_ops.h "esp_partition.h" is included.
This is from spi_flash so component that requires app_update also will need that
this fixes this error:

* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
always used. Also trims the -I path from a number of components that have no actual include
directory.
* Simplifies knowing which components will be header-only and which won't
Makes app image booting more reliable (256-bit rather than 8-bit verification.)
Some measurements, time to boot a 655KB app.bin file and run to app_main() execution.
(All for rev 1 silicon, ie no 340ms spurious WDT delay.)
80MHz QIO mode:
before = 300ms
after = 140ms
40MHz DIO mode:
before = 712ms
after = 577ms
40MHz DIO mode, secure boot enabled
before = 1380ms
after = 934ms
(Secure boot involves two ECC signature verifications (partition table, app) that take approx 300ms each with 80MHz CPU.)
Even if firmware is compiled without CONFIG_FLASH_ENCRYPTION_ENABLED
Rayionale: CONFIG_FLASH_ENCRYPTION_ENABLED controls whether boot loader
generates keys for encryption or not, but flash encryption can be
configured externally. With this change, it's possible to have boot
loader not generate keys but still have encryption working.
Also fix use of it->part
Verify 0xE9 magic byte on first write, verify entire image before
switching.
Enable verification for secure boot signature (was using invalid ifdef
guard)
bugfix/init_factory_bin: fix inconsistency between bootloader and OTA code
init_factory_bin: 2nd bootloader use a wrong logic select factory image to boot,and some bug in OTA code
