[Qemu-devel] [PATCH] hw/arm/virt: add linux, stdout-path to /chosen DT n


From: Ard Biesheuvel
Subject: [Qemu-devel] [PATCH] hw/arm/virt: add linux, stdout-path to /chosen DT node
Date: Fri, 29 Aug 2014 15:03:59 +0200

Add a property "linux,stdout-path" to the /chosen DT node and make
it point to the emulated UART. This allows users such as the Linux
kernel to produce console output without the need to pass console=
or earlycon=pl011,0x... command line arguments.
