Hi All!

Actually there are much more unused header files:

    $ git clone https://github.com/barebox/barebox
    $ cd barebox
    barebox$ for i in $(git grep -h "#.*include" | sed "s/ //g" | grep "^#include" | sed "s/^#include[\"<]//g" | sed "s/[>\"]$//g" | sort | uniq); do basename $i; done | sort | uniq > /tmp/list1
    barebox$ for i in $(find -iname '*.h'); do basename $i; done | sort | uniq > /tmp/list2


Show unused header files:

    barebox$ for i in $(comm -13 /tmp/list1 /tmp/list2); do find -iname $i -type f ; done | grep -v ^./dts/ | sort

Check for false positives:

    barebox$ for i in $(comm -13 /tmp/list1 /tmp/list2); do git grep $i ; done  | grep -v ^dts\/ | grep "#include"
