There are three common NOR flash chip configurations:

1.	Uniform sector -  all sectors are the same size
2.	Bottom boot - There are several smaller sectors at the beginning of
memory space.  For example, 8 x 8k sectors + 127 x 64k sectors.
3.	Top boot - There are several smaller sectors at the end of memory
space.  For example, 127 x 64k sectors + 8 x 8k sectors.

I hope this makes sense.
