Introduce ICSSG PRUETH support in uboot. The ICSSG driver is used in TI
AM654 SR2.0.
The ICSSG PRU Sub-system runs on EMAC firmware. This series Introduces
support for ICSSG driver in uboot.
This series has been tested on AM65x SR2.0, and the ICSSG interface is
able to ping / dhcp and boot kernel using tftp in uboot.
To use ICSSG2 ethernet, the ICSSG firmware needs to be loaded to PRU RPROC
cores and RPROC cores need to be booted with the firmware. This step is
done inside driver similar to kernel.
The remoteproc driver uses request_fw_into_buf() API from fs-loader driver
to load and start rproc with the required firmwares.
This series only introduces driver files. The device tree and config
changes to enable ICSSG driver will be introduced later.
ICSSG firmware supports FDB commands. Add support to send FDB commands
from driver. Once rx_flow_id is obtained from dma, let firmware know that
we are using this rx_flow_id by sending a FDB command.

This is the PRUSS Ethernet driver for TI AM654 SR2.0 and later SoCs with
the ICSSG PRU Sub-system running EMAC firmware. ICSSG Subsystem supports
two slices per instance. This driver caters to both slices / ports of
the icssg subsystem.
Since it is not possible for Ethernet driver to register more than one
port for a given instance, this patch introduces top level PRUETH as
UCLASS_MISC and binds UCLASS_ETH to individual ports in order to support
bringing up more than one Ethernet interface in U-Boot.
Since top level driver is UCLASS_MISC, board files would need to
instantiate the driver explicitly.
