From eace9429516ee6d0d2992e65105f2262efeb1731 Mon Sep 17 00:00:00 2001 From: Peng Fan <peng.fan@nxp.com> Date: Sun, 10 Apr 2022 12:18:27 +0800 Subject: [PATCH] imx8mq: soc: Set the BYPASS ID SWAP bit (GPR10 bit 1) Set the BYPASS ID SWAP bit (GPR10 bit 1). The ID SWAP function randomly make TZASC grant non-secure access to secure memory. TZASC ID SWAP should be bypassed by setting the bit TZASC_ID_SWAP_BYPASS(bit 1) in IOMUX_GPR10 register.
