Rodriguez" This has no functional changes, it just adjusts the ioremap() call for the framebuffer to use the same values we later use for the framebuffer, this will make it easier to review the next change. The size of the framebuffer varies but since this is for PCI we *know* this defaults to 0x800000. atyfb_setup_generic() is *only* used on PCI probe.
