Hi Peng and Stefano,
There were 300+ board defconfig files for QorIQ, and only 100+ board defconfig files for i.MX.
So current patches had minimized code/files changes.
I have rebased the patch-set and sent out adding more reviewers with get_maintainer.pl.
I have no idea and I have to go ahead to split esdhc driver since it's blocking new features coding.
Thanks a lot.
Best regards,
Yangbo Lu
