Hi York,
Thanks,
And is there any other comments for this set of patches?
Or could I send v3 for review?

Please make the patch if you are comfortable. Please
Thanks york,
So it seems I should moving the workaround out of DDR driver in "gen4" to SoC.
I think the workaround is not just only for ddr4.
And It should be as a workaround for the SOC.

LS1021A support both DDR3 and DDR4. DDR4 mode uses this driver, doesn't it?
My concern is if the workaround is implemented in different places, it will be
harder to maintain in future
Hi york,
Is it for DDR4?
LS1021A doesn't use this file.
