[PATCH v2 00/10] 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.

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

[1] http://software-dl.ti.com/processor-sdk-linux/esd/AM65X/latest/index_FDS.html

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
