In the next commit, I need the image name in lowercase because output files are generally named in lowercase. Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase since we generally use uppercase Make variables. make_helpers/build_macros.mk provides 'uppercase' macro to convert a string into uppercase, but 'lowercase' does not exist. We can implement it if we like, but it would be more straightforward to change the argument of TOOL_ADD_IMG. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> |
