Subject: [U-Boot] [PATCH 6/6] ARMv8: LS1043A: Enable LS1043A default PSCI support
Date: Tue, 27 Sep 2016 17:29:06 +0800 [thread overview]
Message-ID: <1474968546-8285-7-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>
A most basic PSCI implementation with only one psci_version is added for
LS1043A, this can verify the generic PSCI framework, and more platform specific
implementation will be added later.
Signed-off-by: Hongbo Zhang <hongbo.zhang@nxp.com>
