Subject: [PATCH 02/17] bus/fslmc: use dmb oshst for synchronization before I/O
Date: Mon, 6 Dec 2021 17:48:09 +0530 [thread overview]
Message-ID: <20211206121824.3493-3-nipun.gupta@nxp.com> (raw)
In-Reply-To: <20211206121824.3493-1-nipun.gupta@nxp.com>
From: Nipun Gupta <nipun.gupta@nxp.com>
Outer Shareable Store (oshst) is sufficient for Data Memory
Barrier (dmb) when doing IO on the interface via QBMAN.
This will sync L3/DDR with the L1/L2 cached data.
Signed-off-by: Nipun Gupta <nipun.gupta@nxp.com>
