bootstd: Correct virtio block-device handling

2023-02-06T18:04:53+00:00

At present virtio tries to attach QEMU services to a bootdev device, which
cannot work. Add a check for this.

Also use bootdev_setup_sibling_blk() to create the bootdev device, since
it allows the correct name to be used and bootdev_get_sibling_blk() to
work as expected.

The bootdev is not created on sandbox since it does have a real virtio
device and it is not possible to read blocks.

virtio: Add some debugging

2023-02-06T18:04:53+00:00

When QEMU does not respond for some reason, it is helpful to have
debugging info to show. Add some.

bootstd: Add a new pre-scan priority for bootdevs

2023-01-23T23:11:41+00:00

We need extensions to be set up before we start trying to boot any of the
bootdevs. Add a new priority before all the others for tht sort of thing.
Also add a 'none' option, so that the first one is not 0.

While we are here, comment enum bootdev_prio_t fully and expand the test
for the 'bootdev hunt' command.

bootstd: Add a virtio bootdev

boot.

virtio: Add a block device

2023-01-23T23:11:40+00:00

The test code for virtio is fairly simplistic and does not actually create
a block device. Add a way to specify the device type in the device tree.
Add a block device so that we can do more testing.

virtio: Avoid strange behaviour on removal

2023-01-23T23:11:40+00:00

This device does a check on removal which is better handled in the actual
test. Move it.

virtio: Fix returning -ENODEV

2023-01-23T23:11:40+00:00

This has a special meaning in driver model. There is clearly a device, so
it does not make sense to return this error code. Fix it.

virtio: Avoid repeating a long expression

2023-01-23T23:11:40+00:00

Use a local variable to hold this name, to reduce the amount of code that
needs to be read.

dm: treewide: Do not opencode uclass_probe_all()

2022-10-18T03:17:12+00:00

We already have a function for probing all devices of a specific class,
use it.

blk: Rename if_type to uclass_id

2022-09-25T14:30:05+00:00

Use the word 'uclass' instead of 'if_type' to complete the conversion.
