ARM: EXYNOS4: Update consistent DMA size to 8MB

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.

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.

Thanks for your review.

Regards,
Hatim Ali

Title : Re: [RESEND PATCH 2/3] ARM: EXYNOS4: Update consistent DMA size to 8MB

Hi,

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

Thank you,
Kyungmin Park
