while this gives 512 MB of usable memory on my AC100, it causes some funny
pictures on the screen ;-) I guess our bootloader (fastboot) already setups
the frambuffer there (and enables the backlight). I guess it shouldn't be
harmful as nothing else writes to this memory area. Otherwise you may add that
the bootloader (or the kernel cmdline supplied by the bootloader) is now
responsible for the reservation to the description.
