If anyone has any objections, please let me know. ------------------ From: Sumit Gupta commit a5e6fc0a10fe280989f1367a3b4f8047c7d00ea6 upstream. Access to safety cluster engine (SCE) fabric registers was blocked by firewall after the introduction of Functional Safety Island in Tegra234. After that, any access by software to SCE registers is correctly resulting in the internal bus error. However, when CPUs try accessing the SCE-fabric registers to print error info, another firewall error occurs as the fabric registers are also firewall protected. This results in a second error to be printed. Disable the SCE fabric node to avoid printing the misleading error. The first error info will be printed by the interrupt from the fabric causing the actual access.
