ENGR00273432 DMA: imx-sdma: Allocate 4KB iram page size for bd One bd actually needs 4KB page size. So changed the iram_alloc() size parameter to allocate a precise iram memory for bd. This patch also removed the extra iram pool for SDMA due to its insufficient total size: SDMA allows around 48 channels to work simultaneously, so it's better to allocate memory from iram pool directly. [There will be 3KB size waste in sdma->channel_control, which is 640B but actually using 4KB due to 4KB alignment for iram pool.] Acked-by: Huang Shijie <b32955@freescale.com> Signed-off-by: Nicolin Chen <b42378@freescale.com>
