Hello
We are currently working on LPDDR4 configuration using the STM32MP257F-DK board. While analysing the setup, we observed that in the stm32mp25-mx.dtsi file, which was generated from STM32CubeMX, certain registers appear to be missing when cross-referenced with the rm0457-stm32mp2325xx-advanced-arm-based-32-64bit-MPUs reference manual.
Additionally, we noticed that these registers are being utilized in the ARM-Trusted-Firmware. However, the addresses of the missing registers fall within the reserved space as per the reference manual.
We have attached a file detailing the specific registers we found missing from the reference manual. Could you kindly verify and provide guidance on where these registers are defined and how we should configure their values?
Thanks & regards
