Can you please explain this a bit more in detail? I checked the source and README for CONFIG_PRAM and it seems to be reserving some space at the end of RAM. But I have only found reference to it in ppc and m68k code. 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?
