Dear Wolfgang Grandegger,

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.
I don't see any functional change in this patch - all you do is renaming VIDEO_FB_16BPP_PIXEL_SWAP into VIDEO_FB_16BPP_WORD_SWAP.
This makes no sense to me.
Please have a look to the patched file. VIDEO_FB_16BPP_PIXEL_SWAP is used in other locations as well. This type of swapping is related to the way the GDC on the Socrates and lwmo5 board is connected.
Wolfgang.
