From: Po-Yu Chuang <ratbert@faraday-tech.com>

This is done by the following command:
$ for f in `find * -type f`; do sed -i 's/\<_end\>/__bss_end__/g' $f; done

Currently, _end is used for end of BSS section.  We want _end to mean
end of u-boot image, so we rename _end to __bss_end__ first.

Yes, I use git send-email.
I guess git put this line to the body because I use a different sender address
(ratbert.chuang@gmail.com) from the one in git config
(ratbert@faraday-tech.com).

I don't know how to fix it, but nobody complained my patches about this.
So I guess this doesn't matter when using git am?

OK, I will fix it.
