It looks safer and cleaner approach to record the measurement taken by BL1 straightaway in TCG Event Log instead of deferring these recordings to BL2. Hence pull in the full-fledged measured boot driver into BL1 that replaces the former ad-hoc platform interfaces i.e. bl1_plat_set_bl2_hash, bl2_plat_get_hash. As a result of this change the BL1 of Arm FVP platform now do the measurements and recordings of below images: 1. FW_CONFIG 2. TB_FW_CONFIG 3.
