-* Description: The block table stores bad block info, including MDF+
-* blocks gone bad over the ages. Therefore, if we have a
-* block table in place, then use it to scan for bad blocks
-* If not, then scan for MDF.
-* Now, a block table will only be found if spectra was already
-* being used. For a fresh flash, we'll go thru scanning for
-* MDF. If spectra was being used, then there is a chance that
-* the MDF has been corrupted. Spectra avoids writing to the
-* first 2 bytes of the spare area to all pages in a block. This
-* covers all known flash devices. However, since flash
-* manufacturers have no standard of where the MDF is stored,
-* this cannot guarantee that the MDF is protected for future
-* devices too. The initial scanning for the block table assures
-* this. It is ok even if the block table is outdated, as all
-* we're looking for are bad block markers.
-* Use this when mounting a file system or starting a
-* new flash.
