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

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.
Changes in v2:
It has been a while since v1 was posted. Here are the changes:
* Removed the usage of misc_init_by_ofnode instead used uclass_get_device_by_ofnode. * Introduced started variable to keep track of the status of the prueth device. * Build Tested on Travis: https://travis-ci.org/Keerthyj/u-boot/builds/651449684
