For some of the MSPI high frequency setting (e.g. 80M DDR mode Flash or PSRAM), timing tuning is required.
Certain delays will be added to the MSPI RX direction. When system clock switches down, the delays should be
cleared. When system clock switches up, the delays should be restored.
spi_flash_generic_timeout is currently defined in the header file,
which makes it a common symbol between translation units where this
header file is included. It is also defined in
spi_flash_chip_generic.c.
Add an explicit `extern` to prevent multiple definition errors.
The implementation allows passing the NULL argument, and the function
is used in the examples accordingly. Fix the discrepancy in the
doxygen comment.

It was when in the partition table there is a partition with type="data" and suptype=""(empty),
in this case type=1, suptype=0. It is similar to otadata partition.
This commit fixes it, now it will handle it as type=1, suptype=6 (ESP_PARTITION_SUBTYPE_DATA_UNDEFINED).
Partially reverted 08f1bbe0c7.
The host should have this flexibility, which is consistent to the cs_hold argument.
However, the user should know as less as possible about the host.
So the wrapper layer (esp_flash_spi_init.c) should cover this, helping to set cs_setup to 1, to meet the common requirements.
* 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
The following three headers will be mockes:
* esp_flash.h
* esp_spi_flash.h
* esp_partition.h
* counter functions live in own header
* add spi_flash sim dir for esp_err.h to Unity
* modified gen_esp_err_to_name.py to ignore
sim/ dir in spi_flash component
Add cmock .yaml config file
Add spi hal header until soc can mock the hal
layer as well.
There is a periodically yield in the esp_flash driver, to ensure the
cache will not be disabled for too long on ESP32.
On ESP32-S2 and later, we need to support more different kind of yield:
1. polling conditions, including timeout, SW read request, etc.
2. wait for events, including HW done/error/auto-suspend, timeout
semaphore, etc.
The check_yield() and yield() is separated into two parts, because we
may need to insert suspend, etc. between them.
* 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
Including:
1. Change the write bytes/read bytes parameter in the host driver into slicers to meet the requirements of complicated cases.
2. Refactor the esp_flash_api code a bit so that we can use the code in the ROM laster
3. Provide get_temp_buffer and release_temp_buffer in the os_functions when the buffer passed by application cannot be used directly.
4. Make timeout of operations configurable in the chip_driver.
5. Make dummy number configurable.
