Log Message:
A VMEbus RAM board configured for use by mvme68k can now be
treated as just another available VMEbus slave image as far as
bus_dma(9) is concerned.

To preserve faster onboard memory, mvmebus_dmamem_alloc() will
allocate first from the offboard VMEbus RAM slave image if present,
and assuming its address modifier matches the caller's constraints.
This can be overidden by specifying the BUS_DMA_ONBOARD_RAM flag.
