BL2 still uses the STM32 header binary format to be loaded from ROM code. BL32 and BL33 and their respective device tree files are now put together in a FIP file. One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are in charge of removing useless nodes for a given BL. This is done because BL2 and BL32 share the same device tree files base. The previous way of booting is still available, the compilation flag STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files are duplicated and their names modified with _stm32_ to avoid too much switches in the code.
