Subject: [PATCH 01/17] armv8: Fix SMCC and ARM_PSCI_FW dependencies
Date: Wed,  1 Jul 2020 19:29:43 +0300	[thread overview]
Message-ID: <20200701162959.9814-2-vicooodin@gmail.com> (raw)
In-Reply-To: <20200701162959.9814-1-vicooodin@gmail.com>

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

Currently SMCC selects ARM_PSCI_FW if enabled which is not correct
as there are cases that PSCI can function without firmware at all.
ARM_PSCI_FW itself is built with driver model approach, so it cannot
be enabled if DM is off.
Fix this by making PSCI reset functionality depend on ARM_PSCI_FW and
only in case if DM is enabled.
