Subject: [PATCH net 2/4] arm64: dts: ls1043a: FMan erratum A050385
Date: Tue, 3 Mar 2020 17:55:37 +0200 [thread overview]
Message-ID: <1583250939-24645-3-git-send-email-madalin.bucur@oss.nxp.com> (raw)
In-Reply-To: <1583250939-24645-1-git-send-email-madalin.bucur@oss.nxp.com>
From: Madalin Bucur <madalin.bucur@nxp.com>
The LS1043A SoC is affected by the A050385 erratum stating that
FMAN DMA read or writes under heavy traffic load may cause FMAN
internal resource leak thus stopping further packet processing.
