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.
for everybody's benefit, where does this firmware come from so one can experiment with this patch series?
From here http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/tree/recipes-bsp/prueth-fw... http://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/tree/recipes-bsp/emac-lld/...

Prebuilt firmware can be obtained from AM65 procSDK [1] rootfs at /lib/firmware/ti-pruss/am65x*.elf

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.
