Are we happy with the base patch? Specifically, having
init_consistent_dma_size() declaired in include/asm/dma-mapping.h?

If so, I don't mind making the changes if Sascha can give me some rules
and pattern to apply. E.g. is it

In mach-imx/mm-imx2*.c

#if defined(CONFIG_VIDEO_MX2_HOSTSUPPORT)
	init_consistent_dma_size(SZ_4M);
#endif

And likewise with CONFIG_MX1_VIDEO in mach-imx/mm-imx1.c and
CONFIG_MX3_VIDEO in mach-imx/mm-imx3*.c.

What about mach-mx5?
