From 940b7128c9d14225b1ce05c586b2023fcbb50454 Mon Sep 17 00:00:00 2001 From: Bryan Brattlof Date: Fri, 23 Dec 2022 19:15:22 -0600 Subject: [PATCH] configs: am62a: move stack and heap to HSM RAM Texas Instruments has begun enabling security setting on the SoCs they produce to instruct ROM and TIFS to begin protecting the Security Management Subsystem (SMS) from other binaries we load into the chip by default. One way ROM does this is by enabling firewalls to protect the OCSRAM region it's using during bootup. Only after TIFS has started (and had time to disable the OCSRAM firewall region) will we have write access to the region. This means we will need to move the stack & heap from OCSRAM to HSM RAM and reduce the size of BSS and the SPL to allow it to fit properly.
