Subject: [U-Boot] [PATCH 5/6] ARMv8: Enable SMC instruction
Date: Tue, 27 Sep 2016 17:29:05 +0800 [thread overview]
Message-ID: <1474968546-8285-6-git-send-email-hongbo.zhang@nxp.com> (raw)
In-Reply-To: <1474968546-8285-1-git-send-email-hongbo.zhang@nxp.com>
From: Hongbo Zhang <hongbo.zhang@nxp.com>
PSCI implementation needs the SMC instruction to be enabled.
Following the legacy codes pattern, no bit macro definition and bit operation
are used, only the immediate data used in line is changed.
