+Subject: [PATCH 1/3] arm: mvebu: Espressobin: move FDT fixup into a separate
+ function
+
+Currently, Esspresobin FDT is being fixed up directly in ft_board_setup()
+which makes it hard to add support for any other board to be fixed up.
+
+So, lets just move the FDT fixup code to a separate function and call it
+if compatible matches, there should be no functional change.

+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.
