Subject: [PATCH v4 13/28] ARM: Update cpu_v7_reset documentation
Date: Tue, 21 Mar 2017 19:20:43 +0000	[thread overview]
Message-ID: <20170321192058.9300-14-marc.zyngier@arm.com> (raw)
In-Reply-To: <20170321192058.9300-1-marc.zyngier@arm.com>

cpu_v7_reset() now takes a second parameter indicating whether
we should reboot in HYP or not. Update the documentation to
reflect this.
