Hi,

> "mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for
> end of dw mmc transfer.
>
> For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) -
> and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB)
> the default timeout is to short.
>
> The new value - 20 seconds - takes into account the situation when SD
> card triggers internal clean up. Such process may take more than 10
> seconds on some cards.
