0010 This selects Hardware reset support aka pwrseq-emmc for eMMC
0011 devices. By default this option is set to y.
0012
0013 This driver can also be built as a module. If so, the module
0014 will be called pwrseq_emmc.

0042 Say Y here to enable the MMC block device driver support.
0043 This provides a block device driver, which you can use to
0044 mount the filesystem. Almost everyone wishing MMC support
0045 should say Y or M here.

0052 help
0053 Number of minors per block device. One is needed for every
0054 partition on the disk (plus one for the whole disk).
0055
0056 Number of total MMC minors available is 256, so your number
0057 of supported block devices will be limited to 256 divided
0058 by this number.
0059
0060 Default is 8 to be backwards compatible with previous
0061 hardwired device numbering.
0062
0063 If unsure, say 8 here.

0075 Development driver that performs a series of reads and writes
0076 to a memory card in order to expose certain well known bugs
0077 in host controllers. The tests are executed by writing to the
0078 "test" file in debugfs under each card. Note that whatever is
0079 on your card will be overwritten by these tests.
0080
0081 This driver is only of interest to those developing or
0082 testing a host driver. Most people should say N here.

0088 Enable Crypto Engine Support in MMC.
0089 Enabling this makes it possible for the kernel to use the crypto
0090 capabilities of the MMC device (if present) to perform crypto
0091 operations on data being transferred to/from the device.
