Subject: [PATCH v2 3/3] ARM: STi: DT: STiH418: Add cpu-release-addr dt property.
Date: Tue, 9 Jun 2015 14:33:44 +0100 [thread overview]
Message-ID: <1433856824-30689-4-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1433856824-30689-1-git-send-email-peter.griffin@linaro.org>
To enable SMP when booting via u-boot we need to specify the
newly implemented cpu-release-addr DT property for cores 2 & 3.
Cores 0 & 1 are inherited from stih407-family.dtsi.
