Subject: [PATCH] qemu: Fix specifying char devs for ARM
|
|
|
|
QEMU ARM boards don't give us any way to explicitly wire in
|
|
a -chardev, so use the old style -serial options.
|
|
|
|
Unfortunately this isn't as simple as just turning off the CHARDEV flag
|
|
for qemu-system-arm, as upcoming virtio support _will_ use device/chardev.
