Subject: [U-Boot] [PATCH 2/5][v5] armv8: Make SEC read/write as snoopable for LS1043
Date: Tue, 8 Dec 2015 13:54:27 +0530 [thread overview]
Message-ID: <1449563070-5761-2-git-send-email-aneesh.bansal@freescale.com> (raw)
In-Reply-To: <1449563070-5761-1-git-send-email-aneesh.bansal@freescale.com>
For LS1043, SEC read/writes are made snoopable by setting
the corresponding bits in SCFG to avoid coherency issues.
