Juan Castillo 73c99d4eb3 Rework Makefile ... This patch is a complete rework of the main Makefile. Functionality remains the same but the code has been reorganized in sections in order to improve readability and facilitate adding future extensions. A new file 'build_macros.mk' has been created and will contain common definitions (variables, macros, etc) that may be used from the main Makefile and other platform specific makefiles. A new macro 'FIP_ADD_IMG' has been introduced and it will allow the platform to specify binary images and the necessary checks for a successful build. Platforms that require a BL30 image no longer need to specify the NEED_BL30 option. The main Makefile is now completely unaware of additional images not built as part of Trusted Firmware, like BL30. It is the platform responsibility to specify images using the macro 'FIP_ADD_IMG'. Juno uses this macro to include the BL30 image in the build. BL33 image is specified in the main Makefile to preserve backward compatibility with the NEED_BL33 option. Otherwise, platform ports that rely on the definition of NEED_BL33 might break. All Trusted Board Boot related definitions have been moved to a separate file 'tbbr_tools.mk'. The main Makefile will include this file unless the platform indicates otherwise by setting the variable 'INCLUDE_TBBR_MK := 0' in the corresponding platform.mk file. This will keep backward compatibility but ideally each platform should include the corresponding TBB .mk file in platform.mk.
