Simon Glass 5a8a8045a9 dm: core: Ensure DMA regions start up with the cache clean ... There is a strange interaction with drivers which use DMA if the cache starts off in a dirty state. Buffer space which the driver reads (but has not previously written) can contain zero bytes from alloc_priv(). This can cause corruption of the memory used by DMA for incoming data. Fix this and add a comment to explain the problem. This allows the dwc2 driver to work correctly with driver model, for example.
