# Common variables:
# BOOT_SCENARIO - determines which tpl (ddrbin), spl and ATF combination to use
#
# Different boot scenario can arrange:
# * Phase 1: DDR initialization (proprietary rockchip ddrbin or u-boot TPL)
# * Phase 2: Initial system and clock initialization (proprietary rockchip miniload or u-boot SPL)
# * Phase 3: Arm Trusted Firmware (proprietary rockchip or mainline opensource)
# * Phase 4: u-boot proper is always the mainline one
#
# Available options for BOOT_SCENARIO are:
# - only-blobs: proprietary rockchip ddrbin, miniloader and ATF
# - spl-blobs: proprietary rockchip ddrin and ATF, but uses mainline u-boot SPL in place of rockchip miniloader
# - tpl-spl-blob: uses mainline u-boot TPL and SPL with proprietary rockchip ATF blob
# - tpl-blob-atf-mainline: proprietary rockchip ddrbin + mainline u-boot SPL + mainline ATF
# - blobless: mainline u-boot TPL + mainline u-boot SPL + mainline ATF
