This adds a transport driver that implements UCLASS_VIRTIO for virtio over pci, which is commonly used on x86. It only supports the legacy interface of the pci transport, which is the default device that QEMU emulates. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

# VirtIO is a virtualization standard for network and disk device drivers
|
|
# where just the guest's device driver "knows" it is running in a virtual
|
|
# environment, and cooperates with the hypervisor. This enables guests to
|
|
# get high performance network and disk operations, and gives most of the
|
|
# performance benefits of paravirtualization. In the U-Boot case, the guest
|
|
# is U-Boot itself, while the virtual environment are normally QEMU targets
|
|
# like ARM, RISC-V and x86.
|
|
#

# See http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf for
|
|
# the VirtIO specification v1.0.
