MX28: Usage of HW_SSP_DDR_CTRL_DMA_BURST_TYPE

[lategoodbye]

Hi, i want to boost MMC performance on MX28 by using DDR mode with Linux.

Are there any recommendation about DMA_BURST_TYPE (e.g. APB transfers per DMA = data width )?

When could be HW_SSP_DDR_CTRL changed? Are there any constraints to the DMA_BURST_TYPE?

Are there any dependencies from other registers?

This register is never changed in 2.6.35 BSP Kernel. Is there a reason for this? Is there any sample code which changes the DMA_BURST_TYPE?

Thanks in advance.

Hi Stefan

there are no known issues/constraints and DMA_BURST_TYPE can be set to 8

if necessary.

Best regards

igor
