Romlib makefile refactoring and script rewriting The features of the previously existing gentbl, genvar and genwrappers scripts were reimplemented in the romlib_generator.py Python script. This resulted in more readable and maintainable code and the script introduces additional features that help dependency handling in makefiles. The assembly templates were separated from the script logic and were collected in the 'templates' directory. The targets and their dependencies were reorganized in the makefile and the dependency handling of included index files is possible now. Incremental build is available in case of modifying the index files. Signed-off-by: Imre Kis <imre.kis@arm.com> Change-Id: I79f65fab9dc5c70d1f6fc8f57b2a3009bf842dc5 2019-07-09 17:30:58 +01:00			`/*`
