One is needed for every 54 partition on the disk (plus one for the whole disk). 55 56 Number of total MMC minors available is 256, so your number 57 of supported block devices will be limited to 256 divided 58 by this number. 59 60 Default is 8 to be backwards compatible with previous 61 hardwired device numbering. 62 63 If unsure, say 8 here. 64 65config SDIO_UART 66 tristate "SDIO UART/GPS class support" 67 depends on TTY 68 help 69 SDIO function driver for SDIO cards that implements the UART 70 class, as well as the GPS class which appears like a UART. 71 72config MMC_TEST 73 tristate "MMC host test driver" 74 help 75 Development driver that performs a series of reads and writes 76 to a memory card in order to expose certain well known bugs 77 in host controllers.

Note that whatever is 79 on your card will be overwritten by these tests. 80 81 This driver is only of interest to those developing or 82 testing a host driver.
