This commit adds a workaround for the TWAI listen only mode errata which is
present on the ESP32, ESP32-S2, ESP32-S3, and ESP32-C3. twai_get_status_info()
has also been updated to account for the fact that TEC/REC are frozen in
listen only mode.
Errata Description:
When the TWAI controller is put into listen only mode, it should not influence
the TWAI bus in any way (i.e., should never send a dominant bit). However,
on the targets listed above, the TWAI controller will send dominant bits in an
error frame (i.e., active error frame), even if the controller is set to listen
only mode.
Workaround:
We can force the TWAI controller into the error passive state on startup (by
setting the REC to >= 128). Since the TEC/REC are frozen in listen only mode,
the TWAI controller will remain error passive and only send recessive bits
(i.e., passive error frames), thus will not influence the TWAI bus.

heap: Fix erroneous value returned by heap_caps_get_allocated_size() when poisoning is enabled (backport v5.0)
See merge request espressif/esp-idf!22187
When light (or comprehensive) poisoning is enabled, the size requested by the user for allocation
is extended by a few bytes to store the canary header and footer. heap_caps_get_allocated_size() should
return the original size asked by the user (without the additional canary bytes).
test_malloc.c extended with a new test assuring that heap_caps_get_allocated_size() returns the proper size
regardless of the degree of poisoning.
IDF_PYTHON_ENV_PATH is the path where the Python environment is created
and used. By default it is inside IDF_TOOLS_PATH. IDF_PYTHON_ENV_PATH
was exported by idf_tools.py but was not imported back. This fixes the
issue and ESP-IDF will honor the value of IDF_PYTHON_ENV_PATH.

Currently loading of esp32s3 ROM ELF symbols fails with
"Cannot access memory at address 0x3ff194ad". Let's perform
add-symbol-file after connection to the target.

This commit fixes an issue where paths on Windows are case insensitive, for instance when setting the build folder its name would be converted to lowercase.
The culprit is our realpath() function, that was calling os.path.normcase() internally, since we are removing that call it makes sense to just remove the function entirely and call os.path.realpath() wherever necessary.

when CONFIG_ESP_SYSTEM_PMP_IDRAM_SPLIT is not set, the PMP rule for esp32c2 shoud allow write access.
Fix esp_cpu_configure_region_protection() in cpu.c accordingly.
Set CONFIG_NEWLIB_TIME_SYSCALL_USE_HRT to enable to force CONFIG_ESP_TIME_FUNCS_USE_RTC_TIMER to disable
and hence prevent the following tests from being executed:
- Timestamp after abort is correct in case RTC & High-res timer have + big error
- Timestamp after restart is correct in case RTC & High-res timer have + big error
- Timestamp after restart is correct in case RTC & High-res timer have - big error
When a public header contains _Static_assert or static_assert, check_public_headers.py script will detect it and report it as an issue.
Indeed, public headers shall now use ESP_STATIC_ASSERT.
This fixes an attempted fix for diram size calculation where it was counted twice, however the fix did not account for cases where iram was not fully filled with cache and therefore was of non 0 size.
Now the calculation should be correct regardless of the cache size.

Fix expected output
On xtensa architecture, the call to __assert_func uses a reference to __func__ that can
sometimes be placed in flash. Since the __asert_func can be called from functions in IRAM
the check_callgraph script can report an error when checking for invalid calls from IRAM
to flash sections. However, the __asert_func prevents this scenario at runtime so the
check_callgraph script reports a 'flas positive' situation. For this reasson, all references
to __func__$x found prior to a call to __assert_func are droped in the parsing of the rtl files.
this commits:
- adds build-time test to check that no call to flash regions are done from IRAM functions
- resolves problems related to IRAM function using content in flash memory
- update heap_caps_alloc_failed to use a default function name in DRAM
when necessary instead of creating a function name variable in DRAM for
each call of heap_caps_alloc_failed. This allows to save some extra bytes
in RAM.
