Norman Feske 0339318572 platform_session: cache arg for alloc_dma_buffer ... This patch extends the 'Platform_session::alloc_dma_buffer' interface with a 'Cache' argument that corresponds to the argument accepted by 'Ram_allocator::alloc', which is used by the platform driver under the hood. Since the x86 platform driver used to be hardwired to allocate DMA buffers as UNCACHED, I adjusted all drivers by specifying the UNCACHED argument. Right now, this is needed as a hint for core to steer the allocation of I/O page tables. Once we eliminate the need for such hints (by introducing an explicit 'Region_map::attach_dma' operation), we can revisit the drivers individually because cached DMA buffers should generally be fine on the x86 architecture.
