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 most data from 2. This scheme breaks down with 
revision 4, which
does not inherit from the earlier models. In addition, the current code has an 
error for Rev. 3
SPROMS. 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 the 
supported drivers (b44,
b43 and b43legacy). 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.
