Well, the lastest 2.5 model working after having some local discusions is:

board files are in /platforms/4xx such as walnut.*, ebony.*

implimentation files are in /kernel/4xx such as ibm405gp.*, ibm44gp.*,
ppc4xx_* & ppc405_*, I guess head should go there too.

the core files like ibm4xx, ibm405.h & ibm440.h are in include/asm-ppc
as well as ibm_ocp.h

Things like ocp.c and ocp_proc will most likely end up in drivers/ocp
since ocp can support more than just ppc.
