Well, I guess I'm a late. I had issues with the getting 4.20+
crosscompiled on debian with make-kpkg. 

Nevertheless, I finally got a working kernel and 
on the MyBook Live APM82181:

---
root at mbl:/sys/kernel/debug# cat ppc4xx_ocm/info 
PPC4XX OCM   : 1
PhysAddr     : 0x0000000400040000[p]
MemTotal     : 32768 Bytes
MemTotal(NC) : 32768 Bytes
MemTotal(C)  : 0 Bytes

NC.PhysAddr  : 0x0000000400040000[p]
NC.VirtAddr  : 0x6bc84b36
NC.MemTotal  : 32768 Bytes
NC.MemFree   : 32768 Bytes

C.PhysAddr   : 0x0000000000000000[p]
C.VirtAddr   : 0x  (null)
C.MemTotal   : 0 Bytes
C.MemFree    : 0 Bytes

Yes, nobody is using the ocm. Though I do have a patch
for the crypto4xx and emac.
