Function now always rewrites old value under same key
regardless existing data type. Users requiring old API behaviour
can enable it by kconfig option CONFIG_NVS_LEGACY_DUP_KEYS_COMPATIBILITY
Users of the nvs API are likely to have `nvs_handle_t` in all cases, but
not all of them carry around the partition name and namespace name (as
they aren't needed after creating an `nvs_handle_t`).
Allow this common case to use nvs iteration without them tracking
additional data by using the `nvs_handle_t` to locate the namespace
index and the partition name by introducing an alterate to
`nvs_entry_find` called `nvs_entry_find_in_handle`, which operates
similarly except that it is given a `nvs_handle_t` instead of partition
and namespace strings.
This is somewhat more limited than the `nvs_entry_find` API as one
cannot examine all keys in a given partition.
- This features allows the NVS encryption keys to be derived and protected using
the HMAC peripheral. Since the encryption keys are derived at runtime, they
are not stored anywhere in the flash and hence this feature does not require
a separate `nvs_keys` partition.
With some libc impls (ie: Xcode 13.1), sprintf is marked as deprecated
and causes the build with `-Werror` to fail. Switch the `sprintf` usage
in test_nvs.cpp to use `snprintf` to allow builds to complete without
warning.
* nvs_page_test runs into timeout in CI. According to log,
test ran run around halfway, so increasing from 10 to 90 seconds.
* Also increased timeout of nvs_host_test, just to be sure
This fixes the issue that "idf.py partition-table" had to be run
manually in order for the partition table to be generated, when
building for linux target.
Host tests of nvs_flash eligible to run in Linux implementation of nvs flash were migrated. Remaining test cases
were left in original folder. Migrated test cases use CMake instead of make.
All the partition handling API functions and data-types were moved from the 'spi_flash' component to the new one named 'esp_partition'. See Storage 5.x migration guide for more details
Unlike COMPILE_OPTIONS, COMPILE_DEFINITIONS CMake property assumes
values without the -D prefix, such as NAME or NAME=VAL.
Previously, IDF build system was passing COMPILE_DEFINITIONS build
property to CMake COMPILE_OPTIONS property, so -D prefix was not
a problem.
Now that COMPILE_DEFINITIONS CMake property is used, -D prefix has
to be removed.
(Note that this doesn't affect 'target_compile_definitions' function,
which strips -D prefix before adding the definition to the property.)
spi_flash driver knows how to write data from cache (DROM or PSRAM)
into flash, so the extra check in nvs_flash is unnecessary.
Besides, the hardcoded address limit (0x3ff00000) is wrong for some
of the newer chips.
Some users have requested this feature.
In order to avoid complete refactoring or introducing more code complexity, a design choice to create temporary files without blank lines is made.
Additionally, an extension check is added and there are multiple smaller code style and structure improvements.

This fixes the issue where multiline strings and strings with delimiters inside the nvs input csv file were incorrectly parsed, and adds back the ability to add comment lines anywhere in the CSV file.
The issue stems from the move away from the python built in csv module to manual parsing, which was made after moving away from using the csv module to parse mfg data.
This reverts back to using the csv module for parsing and writing csv data in both mfg_gen and nvs_partition_gen, fixes the original issue in mfg_gen and improves code quality which makes the code more readable and maintainable.

This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
Closes https://github.com/espressif/esp-idf/issues/7826
* nvs_entry_find(), nvs_entry_next() and nvs_entry_info()
return error codes now
* nvs_entry_find() and nvs_entry_next() access/modify iterator via
parameters, instead of returning an new iterator.
Added appropriate documentation in Chinese and English
add: private include header
add: macro encapsulation for assertion or error check
add: ESP_FAIL return code documentation in public headers
change: replaced all assertions by NVS_ASSERT_OR_RETURN macro
change: few internal function return values from void to esp_err_t
change: ESP_ERR_NVS_VALUE_TOO_LONG macro comment
mbedtls is only required in NVS if NVS encryption is enabled.
Hence the mbedtls dependency is now only added if encryption
is enabled, otherwise it is not added.
BREAKING CHANGE: Removed mbedtls as default dependency
The following files have been ported:
* esp_rom_crc.h
* esp_rom_sys.h
* esp_rom_efuse.h (mostly no-ops)
* esp_rom_md5.h
Integrated Linux-based rom implementation into log
and NVS component.
Added brief host tests for ROM to ensure basic
consistency on Linux.
Added ROM printf host unit tests.
Temporarily added reset reason for Linux in ROM.
