Hi,

Hi,

...

This patchset adds the PL330 DMA driver to U-Boot. The SoCFPGA platform makes use of the PL330 to transfer zereos to the SDRAM which enables the ECC bit.

Is there some considerable performance benefit over memset() in this case ?

Yes, with the DMA, it takes ~1.5 secs, with memset, it's ~15 secs.

Understood, thanks. I hope the scrubbing can be disabled in non-ECC case ?
