Hi kgene
How about this patch? this patch must add the platform data.
Thanks,
Jaehoon Chung

> In mmc, there are capabilities and use the host_caps.
> That capability is expressed with bit[0:31].
> But now..already filled the bit[0:31]...
> so we need to denote with the other capability field.
> (if we want to use the cache, powerclass, etc for eMMC..this field is necessary)
