After updating u-boot from v2016.01 to 2017.09 i got a "SATA link 0 timeout." on my Cubietruck board. I tracked this down to this patch.
http://git.denx.de/?p=u-boot.git;a=commitdiff_plain;h=9fbb0c3aa49f4604b0342c....
After adding the "mdelay(500);" line that was lost in the path the error is gone.
Thank you.
