I have created a pre-patch for the doc. As maintainer I see you with the
script get_maintainer.pl:

$ ./scripts/get_maintainer.pl ./doc/board/emulation/qemu-arm.rst
Tom Rini <trini at konsulko.com> (maintainer:THE REST)
u-boot at lists.denx.de (open list)
$

Created was the file by Tuomas Tynkkynen. Should I send (CC) the patch
to him too?

Thanks in advance!
