From 4ec168a61bfd1a28701c78704fb69dba2a69429a Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Tue, 29 Mar 2022 14:21:25 +0200 Subject: [PATCH] configs: add support of OPTEE RNG in stm32mp15 defconfig When the RNG device is secured with OP-TEE, it is only accessible with the HWRNG TA, the CONFIG_RNG_OPTEE is needed for STM32MP15 targets with OP-TEE support. The probe of this RNG driver fails when the TA is not available in OP-TEE and the previous driver can be used, as CONFIG_RNG_STM32MP1 is activated and when the associated node is activated in the device tree with: &rng1 { status = "okay"; }; When the RNG is used in OP-TEE, this node should be deactivated in the Linux and U-Boot device tree.
