[PATCH v4 0/5] Introduce ICSSG Ethernet driver

[MD Danish Anwar]

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.

This is v4 of the series [1].

Changes from v3 [3] to v4:
*) Dropped the dependncy patches and posted them seprately.
*) Dropped the DTS and config patches, will post them seprately.
*) Modified patch 4/5 to have multi port independent MAC mode support.
*) Rebased the series on latest u-boot/next.

Changes from v2 [2] to v3:
*) No functional changes.
*) Rebased the series on latest u-boot/next.
*) Dropped the RFC tag.

Changes from v1 [1] to v2:
*) Modified the driver to load the firmware inside the driver only instead
   of loading the firmware using commands at u-boot prompt. Added patch
   3/16 for this.
*) Rebased the series on the latest u-boot/next.
*) Modified conf-0 configuration in k3-am65x-binman.dtsi as suggested by
   Roger.
*) Dropped patch [4] as the patch is no longer needed.
*) Added patch 2/15 to modify fs-loader driver to use fw_storage_interface
   env instead of storage_interface and keep the env storage_interface as
   fallback as suggested by Roger.
*) Added patch 15/15 to set default values to env fw_storage_interface and
   fw_dev_part.
