From 92f6a843b81479a9c8f8769d9e728767646b9901 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Tue, 7 Mar 2023 10:35:03 +0100 Subject: [PATCH] board/qemu/aarch64-sbsa: use the default console specified by ACPI ARM SBBR (Server Base Boot Requirements) defines SPCR (Serial Port Console Redirection Table) as a mandatory ACPI table that specifies the configuration of a serial console. In the linux kernel, ARM developers have decided that consoles defined by SPCR are always enabled when existing, see e.g.: https://lore.kernel.org/linux-serial/20200430161438.17640-1-alpernebiyasak@gmail.com/T/ Specifying console=ttyAMA0 (which is a serial console) is thus redundant for an ARM SBSA board. (It also blindly assumes that the serial console is on ttyAMA0, which might not be true.) Drop the explicit console=ttyAMA0 on the kernel command line, such that the kernel can pick up the default console defined by SPCR. This is similar to how it is currently done for board/aarch64-efi/grub.cfg.
