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.
