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. Max
