This patch extends fw_payload blob to provide FW_PAYLOAD_FDT_PATH option using which we can embed custom FDT in .text section of fw_payload blob. In other words, FW_PAYLOAD_FDT_PATH is an option to forcefully override FDT passed by previous booting stage in a1 register. Signed-off-by: Anup Patel <anup.patel@wdc.com>
