Thank you for sharing this document. Looking at the license this is a generic API definition that is not bound to TF-A but might also be implemented on non-TF-A and non-ARM platforms. - Do I get this right? From the view of non-secure firmware like U-Boot or EDK II having a cross-platform specification is preferable.
