121  * @param start - starting block number
123  * @param blksz - size in bytes of each block
126  * @return - '1' if block returned from cache, '0' otherwise.

134  * to the block cache
138  * @param start - starting block number
140  * @param blksz - size in bytes of each block
158  * blkcache_configure() - configure block cache

203 /* Operations on block devices */
206 	 * read() - read from a block device
209 	 * @start:	Start block number to read (0=first)
219 	 * write() - write to a block device
222 	 * @start:	Start block number to write (0=first)
232 	 * erase() - erase a section of a block device
235 	 * @start:	Start block number to erase (0=first)
255 	 * @desc:	Block device to update
279  * blk_find_device() - Find a block device
292  * blk_get_device() - Find and probe a block device ready for use
327  * blk_create_device() - Create a new block device
330  * @drv_name:	Driver name to use for the block device
335  * @blksz:	Block size of the device in bytes (typically 512)
344  * blk_create_devicef() - Create a new named block device
347  * @drv_name:	Driver name to use for the block device

405  * blk_get_from_parent() - obtain a block device by looking up its parent
412  * blk_get_by_device() - Get the block device descriptor for the given device
415  * Return: With block device descriptor on success , NULL if there is no such
416  *	   block device.
464  * struct blk_driver - Driver for block interface types
466  * This provides access to the block devices for each interface type. One
482 	 * get_dev() - get a pointer to a block device given its number
486 	 * There is no global numbering for block devices. This method allows
491 	 * @descp:	Returns pointer to the block device on success
509 	 * @desc:	Block device descriptor
519  * Declare a new U-Boot legacy block driver. New drivers should use driver
530  * blk_get_devnum_by_typename() - Get a block device by type and number
532  * This looks through the available block devices of the given type, returning
535  * @if_type:	Block device type
537  * @return point to block device descriptor, or NULL if not found
542  * blk_get_devnum_by_type() - Get a block device by type name, and number
544  * This looks up the block device type based on @if_typename, then calls
547  * @if_typename:	Block device type name
549  * @return point to block device descriptor, or NULL if not found
557  * This selects a hardware partition (such as is supported by MMC). The block

591  * This shows the block device capacity as well as type-specific information.
593  * @if_type:	Block device type
600  * blk_print_device_num() - show information about a given block device
602  * This is similar to blk_show_device() but returns an error if the block
