Use of OpenAMP in Corstone1000

ARM’s Corstone1000 platform uses openamp for tf-m non-secure communication. The openamp interface is used to recieve messages and send response to the host (Linux). The PSA Client library decodes messages received through OpenAMP and fowards the decoded messages to TF-M’s SPM.

TF-M has Mailbox solution which supports non-secure bare-meta applications. In the Corstone1000, the non-secure side is Linux environment so openamp is used instead.

The file naming convention used here is aligned with TF-M’s secure_fw naming convention. This is just to make sure in future file name does not require change if TF-M adopts this implementation.
