1. call esp_timer_get_time and ref_clock_get in the same order on
start and in the loop
2. disable interrupts when calculating delta between ref_clock
and esp_timer
3. ensure both functions are in cache before calculating the delta
This commit adds the ability for backtracing to trace from the itnerrupt to the
task stack, and across nested interrupts. Test cases have also been added.
See MR !4084
1. fix bug PHY/RTC functions called in ISR (update phy to v4007)
2. add UnitTest to test it
3. fix task watchdog bug when wifi change channel
4. disable/enable agc to mac deinit/init
This commit resolves a blocking in esp_aes_block function.
Introduce:
The problem was in the fact that AES is switched off at the moment when he should give out the processed data. But because of the disabled, the operation can not be completed successfully, there is an infinite hang. The reason for this behavior is that the registers for controlling the inclusion of AES, SHA, MPI have shared registers and they were not protected from sharing.
Fix some related issue with shared using of AES SHA RSA accelerators.

Changes:
KConfig: The option CONFIG_ESP32_RTCDATA_IN_FAST_MEM is added in Kconfig file for esp32 component.
esp32.common.ld: added support of RTC_DATA_ATTR, RTC_RODATA_ATTR data placement into appropriate segment according to Kconfig option.
esp32.ld: linker script is modified to set alias for memory segment selected by Kconfig option to place data. The segments for force placement are added for RTC_FAST_ATTR, RTC_SLOW_ATTR attributes.
esp_attr.h: added new attributes RTC_FAST_ATTR, RTC_SLOW_ATTR for force placement into fest/slow memory.
test_rtc_fast.c: Added unit test cases to check data placement into appropriate memory segment.
Updated documentation for RTC_DATA_ATTR, RTC_FAST_ATTR, RTC_SLOW_ATTR in deep_sleep_stub.rst file.

esp_reset_reason_init would check for reset reason hint, and
unconditionally set RTC_RESET_CAUSE_REG (which is also
RTC_ENTRY_ADDR_REG) to hint value 0, i.e. 0x80000000. However the ROM
code treats this value as valid deep sleep wake stub entry point, and
tries to jump to it.
Clear RTC_RESET_CAUSE_REG only if it contained a valid reset reason
hint, and simply set the register value to 0 when doing so. Also add
a check to esp_get_deep_sleep_wake_stub function that deep sleep wake
stub entry address must be in IRAM.
Reported in https://esp32.com/viewtopic.php?f=13&t=6919.
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.
Before entering the deep sleep, the RTC and FRC counters are synchronized. Updating the boot_time.
Added a unit test for this case.
Fixed warnings for MULTIPLE_STAGES
Closes https://github.com/espressif/esp-idf/issues/1840
1. Fix the WiFi/BT coexist bug
2. Fix WPA2 enterprise example crash bug
3. Add size and version check for crypto type struct
4. Add MD5 check for crypto type header file
Added .rtc_noinit and .noinit section definitions into linker file /esp32/ld/esp32.common.ld.
The macro __NOINIT_ATTR, RTC_NOINIT_ATTR declared in esp32/esp_attr.h file.
Added unit test file to test added behavior for noinit variables and its attributes.
Added documentation changes for new added attributes.
Make some corrections after code review:
The linker file has been corrected to place noinit section before bss_start to make it safer.
Documentation file has been modified to clarify reset behavior of allocated data .
Corrected typos in test_noinit.c and removed assertion of noinit variable to avoid possible issues with ROM boot loader memory allocation.

Update test_noinit.c file to address RTCWDT_RTC_RESET reset reason instead of POWERON_RESET.
Test optimized to pass automated unit testing.
esp32: Add .noinit and .rtc_noinit sections to the linker script
Update of general-notes.rst documentation to fomat examples as code and attributes as identifiers.
Test test_noinit.c corrected to pass automated testing (support ofTEST_CASE_MULTIPLE_STAGES())

When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.
The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.
When light sleep is started, the other CPU gets halted using DPORT
stall mechanism. This can happen while it is inside an esp_timer
critical section, which may lead to a deadlock. This change adds
functions to take and release esp_timer lock before entering
DPORT critical section, preventing the deadlock.
The files updated according to code review discussions.
In the sleep_modes.c removed immidiate disable of ULP mode and leave just trigger deactivation.
The esp_sleep.h is updated to have the same defines for source as esp_sleep_wakeup_cause_t.
Updated documentation in sleep_modes.rst file to include cross references and address esp_sleep_wakeup_cause_t type.
The get_time_ms() is updated to explicitly use fabs(dt) instead of abs(dt) in test_sleep.c.
Some other minor changes in test_sleep.c unit test.
