Subject: [PATCH v3 03/10] ARM: allow secure monitor code to be built without PSCI
Date: Mon, 26 Mar 2018 21:20:18 +0200 [thread overview]
Message-ID: <20180326192025.28809-3-l.stach@pengutronix.de> (raw)
In-Reply-To: <20180326192025.28809-1-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.
