>
> Hi,
> This is the version 5 of HW reset feature implementation. HW reset can
> reset eMMC card when card occurs a read/write/erase timeout error. It is
> useful when eMMC card cannot correspond any command after occurs a
> timeout
> error.
>
> change-log:
> patch1: use value 5 instead to judge whether eMMC card complies eMMC4.41
> standard.
> patch4: handle erase timeout error only when there was an error occurs
> after erase.
>
> patch1: enable HW reset capability if card support.
>
> patch2: add two new callback to implement HW reset in mmc core layer. In
> this patch, routine mmc_handle_timeout_error was added.
>
> patch3: implement hardware_reset callback for sdhci host. A new callback
> reset_emmc was defined which will be each sdhci host controller to
> implement separately.
>
> patch4: did a HW reset after each read/write/erase command if need.
