[TF-M] What do you think using configuration headers in TF-M ?

Hello,

TF-M has many options to configure. All of them are declared as a CMake variables and many of them translated to compiler definitions later. Since the idea of TF-M configuration via config header file(s) was warmly received on the last tech forum I would like to check with community opinion on such hypothetical move: Configure TF-M via definitions in header files while leave CMake for a building control only.

Please share your thoughts, opinions and the possible dependencies.

Thanks, Anton
