From 69a5085219b121a93913f9b0e42436444d5f65fc Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Wed, 14 Feb 2024 10:30:08 -0600 Subject: [PATCH] arm: mach-k3: am62a: Fixup TF-A/OP-TEE reserved-memory node in FDT The address we load TFA and OP-TEE to is configurable by CONFIG_K3_{ATF,OPTEE}_LOAD_ADDR, but the DT nodes reserving this memory are static. Fix that by updating this node when the loaded address does not match the address in DT.
