Subject: [bootwrapper PATCH v2 13/13] Unify start_el3 & start_no_el3
Date: Fri, 14 Jan 2022 10:56:53 +0000	[thread overview]
Message-ID: <20220114105653.3003399-14-mark.rutland@arm.com> (raw)
In-Reply-To: <20220114105653.3003399-1-mark.rutland@arm.com>

Now that the start_el3 and start_no_el3 labels point at the same place,
unify them into a start_bootmethod label and update callers.

There should be no functional change as a result of this patch.
