6# VirtIO is a virtualization standard for network and disk device drivers
7# where just the guest's device driver "knows" it is running in a virtual
8# environment, and cooperates with the hypervisor. This enables guests to
9# get high performance network and disk operations, and gives most of the
10# performance benefits of paravirtualization. In the U-Boot case, the guest
11# is U-Boot itself, while the virtual environment are normally QEMU targets
12# like ARM, RISC-V and x86.
13#
14# See http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf for
15# the VirtIO specification v1.0.
