You mentioned in the cover letter that warmboot_avp.o is special, and
that's the reason that the flags aren't removed from that file. Can you
explain that a bit more? I guess it's because this code is saved for the
AVP to run on resume from LP0, so the code needs to be compiled for AVP.
I"m mainly looking for the commit description to at least briefly
mention this.
