In 16 bpp mode, the new IPEK01 board only requires swapping of D16 words for D32 accesses due to the diffferent connecting to the GDC bus. This patch introduces the configuration option VIDEO_FB_16BPP_WORD_SWAP, which should be set for all board using the mb862xx in 16 bpp mode. For the IPEK01, VIDEO_FB_16BPP_PIXEL_SWAP should not be set.
