Thank you Yunfei for following up with this change.
This change is the last missing piece to enable VD on Kukui with Chromium. This patch fixed the corruption we were seeing on Kukui with certain tests.
One comment from me is just to use defined macro or variable instead of hard coding 64.
"User get width and height are 64 align when set format."
This sentence might need to be reworded. It is not clear to me.
Maybe something like "Width and height need to be 64 bytes aligned when setting the format."
Thanks, Steve
