Yeah, this would be fine for DMA_TO_DEVICE mappings. At least I can't think of a reason right now to not allow it, in the end its also read-only memory for the CPU, so it can be readable by devices too. There is no danger of race conditions like on stacks or data leaks, as there is only compile-time data in rodata.
