Where can I find the file: stm32mp15-ddr-512m-fw-config.dts?

[4layer]

I loaded STM32MP157D-DK1 board configuration in STM32CubeIDE and used the generated device tree files for U-Boot and TF-A compilation. The file MYPROJECT/CA7/DeviceTree/MYPROJECT/tf-a/stm32mp157d-myproject-mx-fw-config.dts contains this line:

#include "stm32mp15-ddr-512m-fw-config.dts"

This causes a fatal error during tf-a compilation due to "No such file or directory".

I searched the internet for this missing file but only found a dead link here: https://wiki.st.com/stm32mpu/wiki/How_to_configure_TF-A_FW_CONFIG

Thanks for any help in advance.

I found it. It appears after applying ST patches on tf-a-stm32mp-v2.4-stm32mp-r2 directory.
