| * | firmware: arm_ffa: Add support for SMCCC as transport to FFA driver | Sudeep Holla | 2021-05-26 | 1 | -0/+5 |
| | | | | | | | | | | | | | | | 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.

| * | firmware: arm_ffa: Add initial FFA bus support for device enumeration | Sudeep Holla | 2021-05-26 | 1 | -0/+16 |
| The Arm FF for Armv8-A specification has concept of endpoints or partitions. In the Normal world, a partition could be a VM when the Virtualization extension is enabled or the kernel itself. In order to handle multiple partitions, we can create a FFA device for each such partition on a dedicated FFA bus. Similarly, different drivers requiring FFA transport can be registered on the same bus. We can match the device and drivers using UUID. This is mostly for the in-kernel users with FFA drivers.
