From: Dinesh Maniyam <[email protected]> The RSU driver-model anchor ("altr,socfpga-rsu") is consumed only by the U-Boot-proper console command, never by SPL. It was previously present only for Agilex, via the socfpga-rsu node under soc@0 in socfpga_soc64_u-boot.dtsi.
The other SoC64 families assemble their devicetree under a "soc" node and pull in only the FIT image overlay (socfpga_soc64_fit-u-boot.dtsi), which carries no SoC nodes, so the anchor never reached them. With CONFIG_SOCFPGA_RSU_DM=y that left rsu_init() returning -ENODEV on Agilex5, Stratix10 and N5X even though the RSU command is enabled there. Add the anchor node to the Agilex5, N5X and Stratix10 U-Boot devicetree overlays, and drop bootph-all from the Agilex node so the anchor is not carried into the pre-relocation/SPL devicetree; it is only needed by the proper-only console command.
