#239: Spurious ECC errors on CAFÉ NAND

 cjb is reporting that the café controller is showing spurious ECC errors.

 http://dev.laptop.org/~cjb/nand-crash shows examples of this (as well as
 the crash which I've assigned to ticket 214). I think they're spurious
 because he says that even when the kernel reported the ECC error during a
 'nanddump' run, the output of nanddump was correct. And because JFFS2 has
 CRCs in _addition_ to the ECC, and it would have complained loudly if a
 CRC failed.
