You should just revert commit 35bddf889652 ("arm: mach-k3: am62x: am625_init: Probe AM65 CPSW NUSS")

what about mach-k3/am64x/am642_init.c?
Please revert the relevant commit there as well.

and the same thing done in mach-k3/common.c?
Please revert the relevant commit there too.

It would be OK if you squash all 3 reverts into one patch.

As a separate patch you will also have to remove the part where cpsw_port2 node is
disabled in various k3-*-u-boot.dtsi files [1]. That is no longer needed as now we should
be able to support multiple ethernet ports.

[1] -
k3-am625-beagleplay-u-boot.dtsi:&cpsw_port2 {
k3-am625-phyboard-lyra-rdk-u-boot.dtsi:&cpsw_port2 {
k3-am625-sk-u-boot.dtsi:&cpsw_port2 {
k3-am642-evm-u-boot.dtsi:&cpsw_port2 {
k3-am642-sk-u-boot.dtsi:&cpsw_port2 {
