| Subject: ARC: [nsimosci] Allow "headless" models to boot |
| |
| From: Vineet Gupta <vgupta@synopsys.com> |
| |
| commit 5c05483e2db91890faa9a7be0a831701a3f442d6 upstream. |
| |
| There are certain test configuration of virtual platform which don't |
| have any real console device (uart/pgu). So add tty0 as a fallback console |
| device to allow system to boot and be accessible via telnet |
| |
| Otherwise with ttyS0 as only console, but 8250 disabled in kernel build, |
| init chokes. |
