 The following OFW command is supposed to do an extensive test of the NAND
 FLASH, adding newly-found bad blocks to the NAND bad block table.
 {{{
 ok test /nandflash::fixbbt
 }}}
 It doesn't work - it claims that lots of blocks are bad when they really
 aren't, and doesn't update the table.  This applies to OFW Q2D16 and
 earlier.

 The workaround:
 {{{
   ok dev /nandflash
   ok : xx dup aa ;  patch xx aa full
   ok dend
 }}}
 After that, the "test /nandflash::fixbbt" command will work.
