ARM: Add a new arch + board for QEMU's 'virt' machine
PATCH 2/2 ARM: Add a new arch + board for QEMU's 'virt' machine
Hello I have successfully built u-boot and launched qemu with the flags proposed by the patch. My problems start when I try to boot the kernel
What is the linux kernel defconfig that should be used to boot this machine? I tried the versatile one but they are different in some key places like the sd card. The end result is that I can only see Starting Kernel, and nothing else. What bootargs do you pass to the kernel to have the serial output in qemu?

multi_v7_defconfig does work at least.

The serial port in Linux is ttyAMA0. But I think it works without any console= specified as well, because the QEMU-generated dtb specifies /chosen/stdout-path already pointing to that serial port.
