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)

v4 changes:
- moved u-boot specific properties to armada-3720-uDPU-u-boot.dtsi
- added additional 'u-boot,dm-pre-reloc' on sdhci1 (eMMC)

I'm wondering, why you don't need any "u-boot,dm-pre-reloc" in your UART DT node.
Other than that:
