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.
