From 44b1d2210f0aa062c45e39860ebdcdbb22c84933 Mon Sep 17 00:00:00 2001 From: Bryan Brattlof Date: Thu, 23 May 2024 11:43:20 -0500 Subject: arm: mach-k3: am62p: Fixup TF-A/OP-TEE reserved-memory node in FDT The address we load TFA and OPTEE is configurable by the CONFIG_K3_{ATF,OPTEE)_LOAD_ADDR, but the DT node reservations remain static which can cause some confusion about where exactly these firmware are exactly. Fix this by updating the reserved-memory{} nodes when the loaded address does not match the address in DT.
