This adds initial support for micro-DPU (uDPU) board which is based on Armada-3720 SoC. micro-DPU is the single-port FTTdp "distribution point unit" made by Methode Electronics which offers complete modularity with replaceable SFP modules both for uplink and downlink (G.hn over twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable). On-board features: - 512 MiB DDR3 - 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC - USB 2.0 Type-C connector - 4GB eMMC - ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type) Cc: Luka Perkov <luka.perkov@sartura.hr> Cc: Luis Torres <luis.torres@methode.com> Cc: Scott Roberts <scott.roberts@telus.com> Cc: Paul Arola <paul.arola@telus.com> Signed-off-by: Vladimir Vid <vladimir.vid@sartura.hr> Reviewed-by: Stefan Roese <sr@denx.de> Signed-off-by: Stefan Roese <sr@denx.de>
