From f811a99ead5ff91b51dc047bc90b2c255934afc5 Mon Sep 17 00:00:00 2001 From: Yann Gautier Date: Tue, 19 Mar 2024 10:59:56 +0100 Subject: [PATCH] docs(st): set OP-TEE as default BL32 Recommend OP-TEE as the default BL32 for STMicroelectronics platforms. SP_MIN is no more supported in STMicroelectronics software [1]. It will then no more receive new features, but should still remain as it is in the TF-A code.
