From now on, we have two tags for esp_flash tests:
- [esp_flash] for main flash chip only tests
- [esp_flash_3] for tests with external flash chips
To Run all tests, type `[esp_flash`; to run tests for main flash chip
only, type `[esp_flash].
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.
1. The 2nd bootloader always call `rom_spiflash_unlock()`, but never help to clear the WEL bit when exit. This may cause system unstability.
This commit helps to clear WEL when flash configuration is done.
**RISK:** When the app starts, it didn't have to clear the WEL before it actually write/erase. But now the very first write/erase operation should be done after a WEL clear. Though the risk is little (all the following write/erase also need to clear the WEL), we still have to test this carefully, especially for those functions used by the OTA.
2. The `rom_spiflash_unlock()` function in the patch of ESP32 may (1) trigger the QPI, (2) clear the QE or (3) fail to unlock the ISSI chips.

QE bit of other chips are at the bit 9 of the status register (i.e. bit 1 of SR2), which should be read by RDSR2 command.
However, the RDSR2 (35H, Read Status 2) command for chip of other vendors happens to be the QIOEN (Enter QPI mode) command of ISSI chips. When the `rom_spiflash_unlock()` function trys to read SR2, it may trigger the QPI of ISSI chips.
Moreover, when `rom_spiflash_unlock()` try to clear the BP4 bit in the status register, QE (bit 6) of ISSI chip may be cleared by accident. Or if the ISSI chip doesn't accept WRSR command with argument of two bytes (since it only have status register of one byte), it may fail to clear the other protect bits (BP0~BP3) as expected.
This commit makes the `rom_spiflash_unlock()` check whether the vendor is issi. if so, `rom_spiflash_unlock()` only send RDSR to read the status register, send WRSR with only 1 byte argument, and also avoid clearing the QE bit (bit 6).
3. `rom_spiflash_unlock()` always send WRSR command to clear protection bits even when there is no protection bit active. And the execution of clearing status registers, which takes about 700us, will also happen even when there's no bits cleared.
This commit skips the clearing of status register if there is no protection bits active.
Also move the execute_flash_command to be a bootloader API; move
implementation of spi_flash_wrap_set to the bootloader
* 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
* changing dependencies from unity->cmock

Sometimes the flash size read from bootloader is not correct. This may
forbid SPI Flash driver from reading the the area larger than the size
in bootloader header.
When the new config option is enabled, the latest configured
ESPTOOLPY_FLAHSIZE in the app header will be used to override the value
read from bootloader header.
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.
In commit 309376f51a, it seems like regression
was added to use ROM level API for disabling flash write protection. This
started random firmware crashes (on specific modules) with exception
`IllegalInstruction` during encrypted flash writes.
Fix here removes relevant ROM API call, since disabling flash write protection
is already ensured by caller of this API.
Closes https://github.com/espressif/esp-idf/issues/5467
Flash write operation is broken down into smaller chunk writes. Size
of this chunk was previously set to 8K but that in-turn meant cache and
non-IRAM resident interrupts could stay disabled upto ~24msec for 8K flash
write operation. If chunk size is brought down to 256 (typical flash page size)
then it brings down cache and non-IRAM interrupts disable duration to ~1msec.
Fix here keeps defaults same but provides configuration option to tweak the
setting based on application requirement.
The SPI bus lock on SPI1 introduces two side effects:
1. The device lock for the main flash requires the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` to be selected, however this
option is disabled by default in earlier IDF versions. Some developers
may find their project cannot be built by their old sdkconfig files.
2. Usually we don't need the lock on the SPI1 bus, due to it's
restrictions. However the overhead still exists in this case, the IRAM
cost for static version of semaphore functions, and the time cost when
getting and releasing the lock.
This commit:
1. Add a CONFIG_SPI_FLASH_BYPASS_MAIN_LOCK option, which will forbid the
space cost, as well as the initialization of the main bus lock.
2. When the option is not selected, the bus lock is used, the
`CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION` will be selected explicitly.
3. Revert default value of `CONFIG_FREERTOS_SUPPORT_STATIC_ALLOCATION`
to `n`.
introduced in 49a48644e4.

We used to manually specify the CS id. However after the SPI bus lock is
introduced, the lock is responsible to assign the CS lines and provide
the CS id. The esp_flash driver now depends on the ID assigned by the
SPI bus lock, the configuration field is deprecated.
The issue is introduced in 571864e8ae. The
esp_flash API tries to clear the QE bit when the flash is not working in
quad modes.
However this introduces a regression, compared to earlier versions and
the legacy API. When the chip is not detected, the generic chip driver
is used, which cannot 100% handle the QE bit properly for all flash
vendors. There may be some flash chips (e.g. MXIC) that can be used in
dual modes by legacy API, but output wrong data when the esp_flash API
clears the QE bit in a wrong way.
This commit reverts the QE force clearing behavior, so that it's safer
for the generic chip driver to work under dual modes.
The default chip driver (chip_generic) use command 01H + 2 bytes to
clear the QE bit. However this will accidently change the configuration
register value of the MXIC chip.
MXIC chip driver is added to fix that.
Allocation of the temporary internal buffer will now repeat until a small enough buffer can be
allocated, and only fail if less than a 256 byte block of internal RAM is free.
Adds unit test for the same, and generic test utility for creating memory pressure.
Previously would try allocate buffer of minimum size 16KB not maximum size 16KB, causing
out of memory errors for any large reads, or if less than 16KB contiguous free heap.
Also, if using legacy API and internal allocation failed then implementation would abort()
instead of returning the error to the caller.
Added test for using large buffers in PSRAM.

Tests for external flash chips used to controlled by macros, one bin for
one chip. And tests are done manually. This commit refactored the test
so that all 3 chips can all run in single test.
There used to be dummy phase before out phase in common command
transactions. This corrupts the data.
The code before never actually operate (clear) the QE bit, once it finds
the QE bit is set. It's hard to check whether the QE set/disable
functions work well.
This commit:
1. Cancel the dummy phase
2. Set and clear the QE bit according to chip settings, allowing tests
for QE bits. However for some chips (Winbond for example), it's not
forced to clear the QE bit if not able to.
3. Also refactor to allow chip_generic and other chips to share the same
code to read and write qe bit; let common command and read command share
configure_host_io_mode.
4. Rename read mode to io mode since maybe we will write data with quad
mode one day.
esp_partition_register_external did not call load_partitions, so if
it was called before any call to esp_partition_find, then the main
partition table would never be loaded. Introduce new function,
ensure_partitions_loaded, and call it both from esp_partition_find and
esp_partition_register_external.

During coredump, dangerous-area-checking should be disabled, and cache
disabling should be replaced by a safer version.
Dangerous-area-checking used to be in the HAL, but it seems to be more
fit to os functions. So it's moved to os functions. Interfaces are
provided to switch between os functions during coredump.
When legacy mode is used, the coredump still fails during linking
because "esp_flash_init_default_chip", "esp_flash_app_init" and
"esp_flash_default_chip " are not compiled and linked.
Instead of using ``if`` macros in callers, these functions are protected
by ``if`` macros in the header, and also not compiled in the sources.
"esp_flash_default_chip" variable is compiled with safe default value.
spi_flash has been updated and its functions work from flash by default instead of IRAM that cause issue
add Kconfig value into espcoredump to enable spi_flash legacy mode (CONFIG_SPI_FLASH_USE_LEGACY_IMPL) when core dump is selected
fix spi_flash issues to work correctly with legacy mode when CONFIG_SPI_FLASH_USE_LEGACY_IMPL is used
Add support for get write protection support, fixed the duplicated
set_write_protection link.
All the write_protection check in the top layer are removed. The lower
levels (chip) should ensure to disable write protection before the
operation start.
The name "start_addr" (which goes straight into the docs) implies
it's an absolute address while in fact it's an offset into the
partition like what's used in all the other esp_partition_*
functions.
So in order to avoid confusion make the name consistent with the
parameter names used for the other partition functions and call it
"offset".

Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
When flash work in DIO Mode, in order to ensure the fast read mode of flash
is a fixed value, we merged the mode bits into address part, and the fast
read mode value is 0 (the default value).
According to the documentation[1][2] for partitions, setting the encrypted
flag for partitions should be a no-op when system level encryption isn't
enabled. The current implementation, however, does not actually match
the documentation and it ends up with an unreadable partition via the
partition API if a partition flag is marked as encrypted without
system-level encryption enabled. (This is because the writes go through
the encryption block, and reads do not go through the encryption block
when this situation occurs causing unreadable data to the application
running.) This fixes up the read-back of the partition table to match
whether or not the partition is currently encrypted under the hood.
This should not affect the bootloader's code for reading/writing encrypted
partitions as the bootloader directly invokes the spi_flash_write*(...)
APIs.

This MR removes the common dependency from every IDF components to the SOC component.
Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.
In CMAKE, we have two kinds of header visibilities (set by include path visibility):
(Assume component A --(depends on)--> B, B is the current component)
1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)
and we have two kinds of depending ways:
(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)
1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)
1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)
This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:
- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h
The major broken include chain includes:
1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h
some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h
BREAKING CHANGE
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
