Header files for 440?

Are there any criteria to define things on so many different header
files for 440 family chips? For example, an Ocotea board has the
following header files.

1. <asm/ibm44x.h>
2. <syslib/ibm440gx_common.h>
3. <syslib/ibm44x_common.h>
4. <platforms/4xx/ibm440gx.h>
5. <platforms/4xx/ocotea.h>

I can understand the reasons why there are ibm44x.h, ibm440gx.h, and
ocotea.h. But why do we need to separate ibm44x_common.h from ibm44x.h
and ibm440gx.h from ibm440gx_common.h? Can we just simply combine them
together? It's a little confusing on what definitions and declarations
should be which files.

Is there any guildeline saying what header file should be in
<asm-ppc/*>, <syslib/*>, or <platforms/4xx/*>?

Any explanations?
