Marek Szyprowski 60641e2259 [media] s5p-mfc: Use preallocated block allocator always for MFC v6+ ... It turned out that all versions of MFC v6+ hardware doesn't have a strict requirement for ALL buffers to be allocated on higher addresses than the firmware base like it was documented for MFC v5. This requirement is true only for the device and per-context buffers. All video data buffers can be allocated anywhere for all MFC v6+ versions. Basing on this fact, the special DMA configuration based on two reserved memory regions is not really needed for MFC v6+ devices, because the memory requirements for the firmware, device and per-context buffers can be fulfilled by the simple probe-time pre-allocated block allocator introduced in previous patch. This patch enables support for such pre-allocated block based allocator always for MFC v6+ devices. Due to the limitations of the memory management subsystem the largest supported size of the pre-allocated buffer when no CMA (Contiguous Memory Allocator) is enabled is 4 MiB. This patch also removes the requirement to provide two reserved memory regions for MFC v6+ devices in device tree. Now the driver is fully functional without them.
