There are requests to keep the transport separate in order to allow other possible transports like virtio. So let us keep the SMCCC transport specific routines abstracted. It is kept simple for now. Once we add another transport, we can develop better abstraction.

This Firmware Framework(FF) for Arm A-profile processors describes
|
|
interfaces that standardize communication between the various
|
|
software images which includes communication between images in
|
|
the Secure world and Normal world. It also leverages the
|
|
virtualization extension to isolate software images provided
|
|
by an ecosystem of vendors from each other.
|
|
|
|
This driver provides interface for all the client drivers making
|
|
use of the features offered by ARM FF-A.
