Subject: [PATCH v3 01/17] firmware: arm_ffa: Update the FF-A command list with v1.1 additions
Date: Fri, 29 Sep 2023 16:02:50 +0100	[thread overview]
Message-ID: <20230929-ffa_v1-1_notif-v3-1-c8e4f15190c8@arm.com> (raw)
In-Reply-To: <20230929-ffa_v1-1_notif-v3-0-c8e4f15190c8@arm.com>

Arm Firmware Framework for A-profile(FFA) v1.1 introduces notifications
and indirect messaging based upon notifications support and extends some
of the memory interfaces.

Let us add all the newly supported FF-A function IDs in the spec.
Also update to the error values and associated handling.
