The core functionality lies in a virtual file system based on a 9p file server

The communication with the 9p layer in BL31 is made through an SMC conduit

buffer is used to pass path string parameters, or e.g. to exchange data on a
read operation. Refer to `ARM SiP Services`_ for a description of the SMC
