···
  * ecc.read_page or ecc.read_page_raw function. Thus, the fact that MTD wants an
  * ECC-based or raw view of the page is implicit in which function it calls
  * (there is a similar pair of ECC-based/raw functions for writing).
- *
- * FIXME: The following paragraph is incorrect, now that there exist
- * ecc.read_oob_raw and ecc.write_oob_raw functions.
- *
- * Since MTD assumes the OOB is not covered by ECC, there is no pair of
- * ECC-based/raw functions for reading or or writing the OOB. The fact that the
- * caller wants an ECC-based or raw view of the page is not propagated down to
- * this driver.
