Subject: [PATCH net v2 2/4] arm64: dts: ls1043a: FMan erratum A050385

From: Madalin Bucur <madalin.bucur@....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.
