Hello Mr. Park,

As I mentioned in the cover letter of v1 patch set (http://www.spinics.net/lists/arm-kernel/msg138054.html),
this is a temporary patch which is just for testing HDMI on SMDKV310.
Once CMA gets merged, we will be using that to allocate memory.

The macro definition CONSISTENT_DMA_SIZE has been removed and has been 
replaced by a function call. Please refer to this patch.

Thanks for your review.

Regards,
Hatim Ali

Hi,

As I know,  CONSISTENT_DMA_SIZE is removed, please use the updated APIs.

Thank you,
Kyungmin Park

Change the consistent DMA allocation to 8MB to support the
TVOUT driver.

NOTE: Once CMA support is merged into mainline, we will use it for memory
allocation.
