30 .Nd driver for SpiFlash(tm) compatible non-volatile storage devices
35 .Bd -ragged -offset indent
36 .Cd "device mx25l"
42 .Bd -literal -offset indent
48 driver provides support for the family of non-volatile storage
55 driver uses opcode 0x9f to read the manufacturer and device ID
56 data to determine whether the device is supported.
57 The device ID is looked up using a table of data within the driver
58 which describes the attributes of each supported device,
59 such as block size, sector size, and device capacity.
60 When a supported device is found, the
62 driver creates a disk device and makes it accessible at
64 The new disk device is then tasted by the available
66 modules as with any disk device.
