New phony Makefile targets have been added: * checkcodebase * checkpatch The checkcodebase target will run a Linux style compliance check over the entire codebase, and honours the V=1 Makefile verbose setting and so will show more information when this is enabled. If the local directory is a git checkout then the output of git ls-files is used to decide which files to test for compliance. If the local directory is not under git control then a 'best attempt' is made, but in this case it should be noted that it is possible for additional non-codebase files to be tested, so care should be taken when parsing the output. The checkpatch target will compare local changes against the git origin/master to allow issues with the last set of changes to be identified. To override the change comparision location, set the BASE_COMMIT variable to your desired git branch. Both targets rely on the Linux source tree script checkpatch.pl to do the syntax checking, and expects that the CHECKPATCH environment variable points to the location of this file. Notes on the usage of these targets have been added to the contributing.md and docs/user-guide.md text files. Change-Id: I6d73c97af578e24a34226d972afadab9d30f1d8d
