Dear Wolfgang Grandegger,

The new IPEK01 board uses the X888RGB mode for the Lime graphics controller. For this mode video accelaration does not work. This patch makes the accelaration configurable via CONFIG_VIDEO_MB862xx_ACCEL, which is enabled for the lwmon5 and the socrates board for backward compatibility.
Why would you want to disable it for IPEK01? Accelaration seems to be a good thing you don't give up if you don't have to, but I cannot think of reasons why you would have to do without it?

Why don't you use memset() here?
