#     powerpc/powernv/npu: Move platform shared code to sysdev
#     
#     Initially NPU support was introduced for the powernv platform only,
#     and later it was extended to pseries so we ended up in a situation when
#     pseries code calls into arch/powerpc/platforms/powernv which is ugly.
#     
#     This moves parts of npu-dma.c required for both powernv and pseries
#     platforms to sysdev.
#     
#     This is mostly cut-n-paste; the only change is:
#     the pnv_npu2_init_context() helper takes a callback pointer which
#     returns void but the empty stub for it defines the callback as it
#     returns a pointer so this fixes it.
#     
#     From now on it is possible to build without POWERNV platform enabled and
#     still have NPU2 support on pseries; currently this fails as:
#     
#     arch/powerpc/platforms/pseries/pci.o: In function `pSeries_final_fixup':
#     /home/aik/p/kernel/arch/powerpc/platforms/pseries/pci.c:267: undefined reference to `pnv_npu2_init'
