The standard location for configuration that is not hardware

IIRC, real Open Firmware used to have some logo configuration, too...
Yep, /options/oem-logo on CHRP LongTrail[1].
And it's even documented[2], but fixed to 64x64 monochrome.

Thank you, that is the answer I was missing. I had written the "a bitmap
is not hardware" objection into the cover letter as something to defend
against, and /chosen turns it into a matter of putting the node in the
right place instead.

v2 moves it there, and I will post it shortly: the node is a child of
/chosen and the kernel looks it up with of_get_compatible_child(of_chosen,
...). The binding now says why, and points at the oem-logo precedent. It
also puts the node in the same company as simple-framebuffer, which lives
under /chosen for the same reason.

Thanks as well for the references, the CHRP one was new to me.
