| 10 | This selects Hardware reset support aka pwrseq-emmc for eMMC | |

| 13 | This driver can also be built as a module. If so, the module | |

| 42 | help | |
| 43 | Say Y here to enable the MMC block device driver support. | |
| 44 | This provides a block device driver, which you can use to | |
| 45 | mount the filesystem. Almost everyone wishing MMC support | |
| 46 | should say Y or M here. | |

| 54 | Number of minors per block device. One is needed for every | |
| 55 | partition on the disk (plus one for the whole disk). | |
| 56 | ||
| 57 | Number of total MMC minors available is 256, so your number | |
| 58 | of supported block devices will be limited to 256 divided | |
| 59 | by this number. | |
| 60 | ||
| 61 | Default is 8 to be backwards compatible with previous | |
| 62 | hardwired device numbering. | |
| 63 | ||
| 64 | If unsure, say 8 here. | |

| 75 | help | |
| 76 | Development driver that performs a series of reads and writes | |
| 77 | to a memory card in order to expose certain well known bugs | |
| 78 | in host controllers. The tests are executed by writing to the | |
| 79 | "test" file in debugfs under each card. Note that whatever is | |
| 80 | on your card will be overwritten by these tests. | |
| 81 | ||
| 82 | This driver is only of interest to those developing or | |
| 83 | testing a host driver. Most people should say N here. | |

| 89 | Enable Crypto Engine Support in MMC. | |
| 90 | Enabling this makes it possible for the kernel to use the crypto | |
| 91 | capabilities of the MMC device (if present) to perform crypto | |
| 92 | operations on data being transferred to/from the device. |
