From c02c69f8ef9020f82f4f09f5108a40b058fbaa06 Mon Sep 17 00:00:00 2001 From: Antonio Nino Diaz Date: Tue, 16 Oct 2018 14:10:15 +0100 Subject: [PATCH] plat/arm: Make crash console functions strong In Arm platforms the crash console doesn't print anything if the crash happens early enough. This happens in all images, not only BL1. The reason is that they the files ``plat/common/aarch64/platform_helpers.S`` and ``plat/arm/common/aarch64/arm_helpers.S``, and the crash console functions are defined as weak in both files. In practice, the linker can pick the one in ``plat/common``, which simply switches the multi console to crash mode when it wants to initialize the crash console. In the case of Arm platforms, there are no console drivers registered at that point, so nothing is printed. This patch makes the functions in plat/arm strong so that they override the weak functions in plat/common.
