This mini-series allows to allocate frame buffer memory in desired location. Allocation of a frame buffer memory in a special memory region allows bypassing of so-called IO Coherency aperture which is typically set as a range 0x8z-0xAz.
I.e. all data traffic to PGU bypasses IO Coherency block and saves its bandwidth for other peripherals.
