Hi Minos,

Thanks for the swift answer.  What I found in the documentation is this:

https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBuild/artifact/build-docs/tf-m_documents/install/doc/user_guide/html/docs/user_guides/tfm_integration_guide.html#platform-retarget-files

https://ci.trustedfirmware.org/job/tf-m-build-test-nightly/lastSuccessfulBuild/artifact/build-docs/tf-m_documents/install/doc/user_guide/html/docs/user_guides/tfm_integration_guide.html#how-to-add-a-new-platform

It does not really describe the purpose of that files.  Maybe I have missed something.

Please consider my question as example. I’m am looking for a description of all the platform files.
