On certain TI SoC, like AM64x there is a CPSW3G which supports 2 external independent MAC ports for single CPSW instance. It is not possible for Ethernet driver to register more than one port for given instance.
This patch modifies top level CPSW NUSS as UCLASS_MISC and binds UCLASS_ETH to individual ports so as to support bring up more than one Ethernet interface in U-Boot.
Note that there is no isolation in the since, CPSW NUSS is in promisc mode and forwards all packets to host.
Since top level driver is now UCLASS_MISC, board files would need to instantiate this driver explicitly.

Applied to u-boot/master, thanks!
