Subject: [PATCH v2 03/10] ARM: allow secure monitor code to be built without PSCI
Date: Sat, 24 Mar 2018 00:14:15 +0100 [thread overview]
Message-ID: <20180323231422.21137-3-l.stach@pengutronix.de> (raw)
In-Reply-To: <20180323231422.21137-1-l.stach@pengutronix.de>
The hyp mode handling added in the secure monitor code is also useful
when Barebox doesn't have PSCI control. Allow to build without PSCI.
