Well, I'm not sure what's going on with the code. I *think* what's happening is that the first call of_platform_bus_probe() is scanning most, but not all, of the tree, and it's somehow reserving all of those nodes. Then we call of_platform_bus_probe() again, but it never finds the DMA nodes. of_platform_bus_probe() never actually calls of_platform_bus_create() this time around. Perhaps the recursive nature of of_platform_bus_create() is part of the problem.
The only fix I can think of is to move "fsl,eloplus-dma" into mpc85xx_common_ids[]. I'll post a patch that does that, and we can discuss it.
