This looks like a hack. Please find out why the Ethernet driver is not being probed when SPL tries to load image over net.
We have the following defined at the am65-cpsw-nuss driver.
U_BOOT_DRIVER(am65_cpsw_nuss) = { .name = "am65_cpsw_nuss", .id = UCLASS_MISC, .of_match = am65_cpsw_nuss_ids, .probe = am65_cpsw_probe_nuss, .priv_auto = sizeof(struct am65_cpsw_common), };
U_BOOT_DRIVER(am65_cpsw_nuss_port) = { .name = "am65_cpsw_nuss_port", .id = UCLASS_ETH, .probe = am65_cpsw_port_probe, .ops = &am65_cpsw_ops, .priv_auto = sizeof(struct am65_cpsw_priv), .plat_auto = sizeof(struct eth_pdata), .flags = DM_FLAG_ALLOC_PRIV_DMA | DM_FLAG_OS_PREPARE, };
It looks like am65_cpsw_probe_nuss() is not being invoked for you.
Can you please check if am65_cpsw_port_probe() was invoked? If yes but am65_cpsw_probe_nuss() was not then we need to fix the DM hierarchy for AM65_CPSW?
