Make Ada a first class citizen
Some remarks on the make process: o We usually leave Ada specs (.ads files which are like c headers) together with the bodies (implementations in .adb files) in one directory. So we have to know, where they live. o If there is no matching .adb an .ads is a valid source file and we'll generate an object file from it. o Object files need to have the same basename as their source files :-/ That's why we put them in build/<class>/ dirs now. o We track dependencies by looking at the compiler output (.ali files which accompany every .o). This way we don't need any gnatmake magic, or even more complex, less portable tools. For ADAFLAGS_common, I simply copied the CFLAGS_common whilst dropping everything unsupported and adding sane warning options. The set of language features is highly restricted (see gnat.adc). This should suit the embedded nature of coreboot and helps proving absence of runtime errors with SPARK.
