ramips: split base-files into subtargets
While most of the target's contents are split into subtargets, the base-files are maintained for the target as a whole. However, OpenWrt already implements a mechanism that will use (and even prefer) files in the subtargets' directories. This can be exploited to make several scripts subtarget-specific and thus save some space. In certain cases, keeping files in parent (=target) base-files was more convenient, and thus no splitting was performed for those. Note that this will increase overall code lines, but reduce code per subtarget. base-files ipk size reduction: master (mt7621) 60958 B split (mt7620) 46358 B (- 14.3 kiB) split (mt7621) 48759 B (- 11.9 kiB) split (mt76x8) 44948 B (- 15.6 kiB) split (rt288x) 43508 B (- 17.0 kiB) split (rt305x) 45616 B (- 15.0 kiB) split (rt3883) 44176 B (- 16.4 kiB) Run-tested on: GL.iNet GL-MT300N-V2 (mt76x8) D-Link DWR-116 (mt7620) Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
