The series introduces device tree and config changes and AM65x to enable ICSSG driver. The series also enables SPL_LOAD_FIT_APPLY_OVERLAY for AM65x in order to load overlay over spl.
The ICSSG2 node is added in device tree overlay so that it remains in sync with linux kernel. 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. The users need to set env variables fw_storage_interface, fw_dev_part, fw_ubi_mtdpart, fw_ubi_volume to indicate which storage medium and partition they want to use to load firmware files from. By default the env fw_storage_interface=mmc and fw_dev_part=1:2 but users can modify these envs as per their requirements. This is the v4 of the series [1]. The series doesn't depend on any patch and can be applied cleanly on u-boot/master Changes from v3 to v4: *) Separated the device tree and board specific changes into this series from the main series [1]. *) Added check for TARGET_AM654_A53_EVM config in board file as suggested by Dan Carpenter <dan.carpen...@linaro.org> *) Rebased on latest u-boot/master.
