Todo's so far (from Alan Cox)
- Fix firmware loading
- Get firmware into firmware git tree
- Review and tidy each algorithm function
- Check whether it can be plugged into any of the kernel crypto API
interfaces
- Do something about the magic shared memory interface and replace it
with something saner (in Linux terms)

* 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 It is ok even if the block table is outdated, as all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.
