It seems that Soong is not meant to work with those .mk files though;
its page talks about newer JSON-like "Android.bp" files that supersede
the older make-based Android.mk files[1].

The documentation is terrible, it totally unclear whether .bp or .mk files are used. Maybe .bp file are transistional files only. Who knows?

For platform/system/core [1] there is a .bp file (and a .mk file), but for e.g. fastboot (which is part of system/core) [2] there is only a .mk file, while for soong there is a .bp file again [3]

Interesting (just discovered):

After running "repo sync" the directory .repo/projects/build contains blueprint.git, kati.git, make.git and soong.git. So I assume there are the tools to start with.

• kati – https://android.googlesource.com/platform/build/kati

based on Makefile (two others will be ncluded), implemented in C and Go
.travis.yml available, is building the C implementation
build seems to require ninja (according to travis.yml), but makefile does not use it
tests require ruby
.rravix.yml seems to run more tests than test-target

• blueprint – https://android.googlesource.com/platform/build/blueprint

.travis.yml available
build seems to require ninja and go (according to travis.yml)

• make – https://android.googlesource.com/platform/build

Seems to include a lot if Makefiles to be included by Makefiles. There is a README. Scanning ofer this I assume, that this is the "meta-make" for building the android platform (commands m, mm, mmm).

• soong – https://android.googlesource.com/platform/build/soong/
