[SeaBIOS] [PATCH v2 0/2] Initialize only bootable virtio-blk/virtio-blk
This patch aimed to avoid problem with uninitialized virtio-blk and
virtio-scsi boot devices.
Currently, 12 KiB of memory is allocated for each virtio-blk/scsi, so
no more than about 10 devices can be initialized. If the device is not
initialized, we cannot boot from it. So, if we have more than 10 devices,
we can't boot from any of the following (11, 12, etc.).
We can initialize only bootable devices, i.e. listed in boot order list,
that this patch does.
Alexey Kirillov (2):
boot: Detect strict boot order (HALT record) in function
virtio: Do not init non-bootable devices
