From 1a314099b7559690fe23cdf3300dfff6e830ecb1 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Thu, 1 Aug 2024 13:12:32 -0500 Subject: [PATCH] arm64: dts: ti: k3-j721e-beagleboneai64: Fix reversed C6x carveout locations The DMA carveout for the C6x core 0 is at 0xa6000000 and core 1 is at 0xa7000000. These are reversed in DT. While both C6x can access either region, so this is not normally a problem, but if we start restricting the memory each core can access (such as with firewalls) the cores accessing the regions for the wrong core will not work. Fix this here.
