Replace Makefile 'tags' target with 'xrefs', clean it up
This adds a 'xrefs' target to create various cross-reference files from the
EC sources. In particular, it generates these files in the target build
directory:
cscope.files - for the cscope browsing tool
TAGS - for emacs
tags - for vi
It parses the dependency files generated by a build, so that only those
source files actually used to create the EC binary are scanned.
BUG=chrome-os-partner:18343
BRANCH=none
TEST=manual
Inside the chroot:
make BOARD=link xrefs
ls -l build/link/cscope.files
If you install the ctags and etags programs in the chroot, you should also
see build/$BOARD/tags or build/$BOARD/TAGS, respectively. If those programs
don't exist, those steps will be silently skipped.
Note: You can install ctags with "sudo emerge ctags". AFAICT, installing
etags requires the entire emacs suite, so it's probably simpler to just copy
the etags binary from your build host into the chroot's /opt/bin/
If you don't have ctags or etags in the chroot, you can still run
make BOARD=link CROSS_COMPILE= xrefs
outside the chroot, provided you've built the EC image first.
