[RFC 1/2] virtio_console: Add support for DMA memory allocation
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Add feature VIRTIO_CONSOLE_F_DMA_MEM. If the architecture has
DMA support and this feature bit is set, the virtio data buffers
will be allocated from DMA memory.
This is needed for using virtio_console from the remoteproc
framework.

Add feature VIRTIO_CONSOLE_F_DMA_MEM. If the architecture has
DMA support and this feature bit is set, the virtio data buffers

the feature VIRTIO_CONSOLE_F_DMA_MEM, but the architecture
