For TF-A, there is no format specified for functional documentation. For AMD-Xilinx platforms, following kernel-doc format for the functional documentation to make sure AMD-xilinx documentation is align with actual code. For example use kernel-doc from linux to call: <linux>/scripts/kernel-doc -man -v 1 >/dev/null file...
