remoteproc DMA API abuse status

[Christoph Hellwig]

Hi remoteproc maintainers,

did you make any progress to get remoteproc out of creating fake
devices that fake their dma ops status and the abuse of
dma_declare_coherent_memory in removeproc_virtio?  I remember we had
a discussion on this a long time ago, and there was an unfinished
patchset to change the memory pool handling.  What happened to all that?
