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.
