From d703aa3db7a3f6db81c6dcd03a8f462864e19144 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Wed, 17 May 2023 16:53:24 +0100 Subject: [PATCH] ARM: dts: bcm27xx: Add stdout-path to serial0 Rather than deleting the upstream stdout-path declaration, overwrite it with one selecting serial0, which will always be the UART mapped to the 40-pin header (provided enable_uart=1 is specified). Doing so has the advantage that earlycon can be configured just by adding "earlycon" to the command line.
