[U-Boot] [PATCH 00/14] net: ti: icssg: Add prueth support

[Keerthy]

The series adds support for icssg_prueth functionality
on u-boot. This series is based on top of master branch.
rproc init needs to be done from uboot command prompt.
The pru/rtu firmware loading is done by prueth driver soon after
config paramters are setup.

Currently only slice0/1 of icssg2 instance on am6-evm
is supported. i.e Both slices of icssg2 instance are supported.

On u-boot prompt following commands to test icssg2_port 0 on am654-evm:

setenv ethact pruss2_eth;  setenv serverip 172.24.191.45; fatload mmc 1 ${pru0loadaddr} am65x-pru0-prueth-fw.elf; fatload mmc 1 ${rtu0loadaddr} am65x-rtu0-prueth-fw.elf; rproc init; setenv autoload no; dhcp; tftp 0x82000000 Image; tftp 0x83000000 k3-am654-base-board.dtb; booti 0x82000000 - 0x83000000

This tests tftp on prueth.

Note: Uboot ethernet driver architecture supports once
instance per probe. So only one of the ports are supported
per instance. So DT of prueth node should have either ethernet-mii0
or ethernet-mii1.
