Crates for building device driver subsystems in the no_std environment:

• axdriver_base: Common interfaces for all kinds of device drivers.
• axdriver_block: Common traits and types for block storage drivers.
• axdriver_net: Common traits and types for network device (NIC) drivers.
• axdriver_display: Common traits and types for graphics device drivers.
• axdriver_pci: Structures and functions for PCI bus operations.
• axdriver_virtio: Wrappers of some devices in the virtio-drivers crate, that implement traits in the axdriver-series crates.
