Hi all,

This patchset adds support for using FF-A notifications as a delivery
mechanism of asynchronous notifications from OP-TEE running in the secure
world. Support for asynchronous notifications via the SMC ABI was added in
[1], here we add the counterpart needed when using the the FF-A ABI.

Support for FF-A notifications is added with [2] and this patch set is based
on Sudeeps tree at [3].
