[PATCH 0/8] ARM: ti: AM64x: Add Ethernet boot support on AM64x SK

This series enables ethernet boot support on AM64x SK.

AM64x SoC has CPSW3g IP that supports 2 ext Eth port. ROM supports
booting from 2nd port. But currently am65-cpsw-nuss only
supports single port (1st port). So the first two patches modify
driver to support more than 1 ext port.
This is done by breaking up am65-cpsw-nuss into UCLASS_MISC for toplevel
NUSS driver and UCLASS_ETH for each of individual ports.

Next 4 patches add mach-k3 and board level changes to enable Ethernet
and TFTP to work at SPL.

Last two patches add dts and config changes need to for Ethernet boot.

Tested on AM64x SK with RGMII 1G bootmode at 1G.

Sanity tested TFTP at U-Boot prompt on AM65x and J721e.
