error: implicit declaration of function 'soc_has_cache_lock_bug' when ESP_INT_WDT option is disabled if SPIRAM is enabled (IDFGH-8889)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

ESP-IDF v5.0.0

Operating System used.

Linux

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

None

What is the expected behavior?

It compiles the software successfully. (although it may fail at runtime due to SPIRAM dependency on INT_WDT).
I guess that Kconfig should add INT_WDT as a dependency of SPIRAM such a way that if SPIRAM is enabled INT_WDT is also enabled

What is the actual behavior?

The next error is returned

esp-idf/components/freertos/FreeRTOS-Kernel/portable/xtensa/port.c: In function 'esp_startup_start_app':
esp-idf/components/freertos/FreeRTOS-Kernel/portable/xtensa/port.c:486:13: error: implicit declaration of function 'soc_has_cache_lock_bug' [-Werror=implicit-function-declaration]
  486 |     assert(!soc_has_cache_lock_bug() && "ESP32 Rev 3 + Dual Core + PSRAM requires INT WDT enabled in project config!");

Steps to reproduce.

1. Make a copy of the hello world example
2. Run idf.py menuconfig enable SPIRAM option and disable ESP_INT_WDT
3. Run idf.py build

Hi,

The issue seems to be that esp_chip_info.h is missing from port.c, we'll fix that.

As for making INT_WDT depend on SPIRAM in kconfig, I think the problem here is that we do not know the ECO version at compile time. so this will have to stay as a run-time check for now I think.
