Subject: [PATCH v2 02/18] firmware: arm_ffa: Replace UUID buffer to standard UUID format
Date: Fri, 31 Jan 2025 11:24:02 +0000 [thread overview]
Message-ID: <20250131-ffa_updates-v2-2-544ba4e35387@arm.com> (raw)
In-Reply-To: <20250131-ffa_updates-v2-0-544ba4e35387@arm.com>
Currently ffa_partition_info structure holds the UUID in the format
compatible with the firmware interface. However, most of the functions
in the FF-A core driver deals directly with uuid_t type.
Replace UUID buffer to standard UUID format in the ffa_partition_info
structure.
