> Mini u-boot eMMC dt parameters are not in sync with full u-boot dt.
>
> Frequency for eMMC is fixed to 25Mhz. Due to this, mmc multi-block write
> commands are failing. Increase frequency to 200Mhz to fix this issue.
>
> Add bus-width = <8>, non-removable and disable-wp properties to the node
> as this is eMMC.
