To highlight warnings during build. It's just a way to make the default
output less noise.

-s is a bit to much you get no feedback at all.

with errors I guess you mean non optimal output. the patch really should
not have any impact on the binaries built. If it really breaks the build
that is a real problem and one I do not see in my test.

No it's only a way to remove most of the noise as mentioned it has no
effect on u-boot itself. 

while it's a large patch it's mostly trivial search/replace so it's easy
to remove should people object to it.

But please try it out for a while and see what people think. My guess is
that the amount of warnings showing up during build will be reduced over
time with this type of feedback during build.


here is a small addition to the patch fixing the issues with -s you
found.
