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
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.
Closes https://github.com/espressif/esp-idf/issues/8421
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.

* 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
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.
* General tests like page loading from flash
* Rough test of fixed-size data types
* Rough test of blob read
* Added coverage target in cmake, also accessible
via `idf.py coverage`
* Fixed unsigned comparison in comp. enum table
* introducing temporary LINUX_TARGET define
* When deinitializing or erasing a partition,
nvs used to close all handles instead of only
the current partition's handles.
This is fixed now
* Added a unit test for that case
Closes FCS-533
* partition api changed from spi_flash* API to
esp_partition* API and is abstracted as a C++
interface.
* The old nvs encryption is still possible
* changed default unit test app partition table
* Partitions coming from esp_partition API are
checked for generic flash encryption. If yes,
an error is returned since generic flash
encryption isn't compatible with nvs
encryption
* esp32, esp32s2 tests don't require nvs_flash
but mbedtls now
Closes IDF-1340
Closes IDF-858
This prevents wear and tear on the flash, and it also is faster in some
cases since the read-out of flash is a cheaper operation than the erasure
of flash. Some library modules (such as the esp_wifi) write out to NVS
upon every initialization without checking first that the existing value
is the same, and this speeds up initialization of modules that make
these design choices and moves it into a centralized place.
The comparison functions are based on the read-out functions of the same
name, and changes out the memcpy(...) operations for memcmp(...)
operations.

Earlier eraseItem function in Storage class would do lazy cleanup of
multi-page blobs if called using type "ANY" instead of "BLOB". It used to
just delete BLOB data and index would remain as is. Any subsequent read
would delete index entry as well. This however would return a valid
length without error if nvs_get_blob API was just used for finding
length and not reading the complete blob. This change fixes this issue.

1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
Previously when HashList was removing items, HashListBlocks were
removed lazily. This resulted in empty HashListBlocks dangling around
in full pages, even when all items have been erased. These blocks
would only be deleted when NVS was re-initialized
(nvs_flash_deinit/nvs_flash_init).
This change does eager cleanup instead, based on the code from
@negativekelvin offered in
https://github.com/espressif/esp-idf/issues/1642#issuecomment-367227994.
