- * @read_page_raw: function to read a raw page without ECC

+ * @read_page_raw: function to read a raw page without ECC. This function
+ * should hide the specific layout used by the ECC
+ * controller and always return contiguous in-band and
+ * out-of-band data even if they're not stored
+ * contiguously on the NAND chip (e.g.
+ * NAND_ECC_HW_SYNDROME interleaves in-band and
+ * out-of-band data).
+ * @write_page_raw: function to write a raw page without ECC. This function
+ * should hide the specific layout used by the ECC
+ * controller and consider the passed data as contiguous
+ * in-band and out-of-band data. ECC controller is
+ * responsible for doing the appropriate transformations
+ * to adapt to its specific layout (e.g.
+ * NAND_ECC_HW_SYNDROME interleaves in-band and
