Right. But there is a chance that the ARM implementation might be reworked soon, and then it will follow the documented approach as well, so better start correctly from the beginning so you don;t run into conflicts soon. > What would be the correct way to reserve some 2MB-4MB at the end of > system RAM as a framebuffer for the integrated graphics device? See the PPC implementation for reference.
