+ * This calls blk_get_device_str() to look up a device. It also looks up

+ * @dev_part_str is in the format:
+ *	<dev>.<hw_part>:<part> where <dev> is the device number,
+ *	<hw_part> is the optional hardware partition number and
+ *	<part> is the partition number
+ *
+ * If ifname is "hostfs" then this function returns the sandbox host block
+ * device.
+ *
+ * If ifname is ubi, then this function returns 0, with @info set to a
+ * special UBI device.
+ *
+ * If @dev_part_str is NULL or empty or "-", then this function looks up
+ * the "bootdevice" environment variable and uses that string instead.
+ *
+ * If the partition string is empty then the first partition is used. If the
+ * partition string is "auto" then the first bootable partition is used.
+ *
+ * @ifname:	Interface name (e.g. "ide", "scsi")
+ * @dev_part_str:	Device and partition string
+ * @dev_desc:	Returns a pointer to the block device on success
+ * @info:	Returns partition information
+ * @allow_whole_dev:	true to allow the user to select partition 0
+ *		(which means the whole device), false to require a valid
+ *		partition number >= 1
