layer with the flash_hw_if structure. This structure has
function pointers and other fields.
The attachment can be done by calling
flash_attach_mi
() with this structure and the
device's device_t as an argument. Return value is the
flash layer device. The flash_interface structure is
shown below.
struct flash_interface { int (*erase) (device_t, struct flash_erase_instruction *); int (*read) (device_t, off_t, size_t, size_t *, uint8_t *); int (*write) (device_t, off_t, size_t, size_t *, const uint8_t *); int (*block_markbad)(device_t, uint64_t); int (*block_isbad)(device_t, uint64_t); int (*sync) (device_t); int (*submit)(device_t, struct buf *); /* storage for partition info */ struct flash_partition partition; /* total size of mtd */ flash_addr_t size; uint32_t page_size; uint32_t erasesize; uint32_t writesize; uint32_t minor; uint8_t type; };
