In the various Broadcom devices that are supported, several revisions of the 
SPROM have been
encountered. Current code takes advantage of the fact that Revision 2 inherits 
all the data of
1, and that Revision 3 inherits from 2. This scheme breaks down with revision 
4, which does not
inherit from the earlier models. In deciding how best to implement the new 
design, a fresh approach
is warranted. Furthermore, we decided not to include any SPROM variables not 
used in b44, b43 or
b43legacy, the supported drivers. To keep the patches small while preserving 
compilation and correct
execution during bisection, the change has been split into the following pieces:

1. Introduce new structure while maintaining the old.
2. Convert the ssb module to the new structure.
3. Convert the b44 driver.
4. Convert b43.
5. convert b43legacy.
6. Remove the old structures from ssb.
