-Subject: [PATCH 3/3] arm: mvebu: eDPU: support new board revision
-
-There is a new eDPU revision that uses Marvell 88E6361 switch onboard.
-We can rely on detecting the switch to enable and fixup the Linux DTS
-so a single DTS can be used.
-
-There is currently no support for the 88E6361 switch and thus no working
-networking in U-Boot, so we disable both ports.
-
