Because BKOPS on eMMC4.41 is optional. So the capability is provided for the platform to either enable/disable this feature (its not mandatory to always enable BKOPS on 4.41) > Maybe we had discussed about this point. i know that we can enable the BKOPS with the mmc-util. > (Actually, This code had included into my first patch. but it's removed.) I'm not aware of this discussion and currently I'm running on eMMC4.41 and bkops is supported but not enabled. So i suggested this patch. Do you mean to say, right now, i can enable it using mmc-utils? Will you please elaborate? Thanks, Prasanna
