Good timing. We are close to send some updates to UFS which we require to get 
DWC version to work inside U-Boot.

How far are that core changes from Linux? I see 9/13 is sync with Linux but when 
this is done you should also say which Linux version was used for sync.

I see that there are definitely some kernel-doc issues

Also s/U-boot/U-Boot/g

Venkatesh: Can you please look at this patch series and validate it on our 
platform? Also make sense to send our changes to make sure that they won't break 
others.

Thanks,
Michal
