From af2880ec44021d32cc72a5aa7c5d7d7beaa722d3 Mon Sep 17 00:00:00 2001 From: Robin Murphy <robin.murphy@arm.com> Date: Mon, 12 Jun 2023 16:31:56 +0100 Subject: scatterlist: add dedicated config for DMA flags The DMA flags field will be useful for users beyond PCI P2P, so upgrade to its own dedicated config option.
