dm: Add a new uclass driver for VirtIO transport devices This adds a new virtio uclass driver for “virtio” [1] family of devices that are are found in virtual environments like QEMU, yet by design they look like physical devices to the guest. The uclass driver provides child_pre_probe() and child_post_probe() methods to do some common operations for virtio device drivers like device and driver supported feature negotiation, etc. [1] http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdf Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> 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.

This option is selected by any driver which implements the virtio
transport, such as CONFIG_VIRTIO_MMIO or CONFIG_VIRTIO_PCI.
virtio: Add virtio over mmio transport driver VirtIO can use various different buses and virtio devices are commonly implemented as PCI devices. But virtual environments without PCI support (a common situation in embedded devices models) might use simple memory mapped device (“virtio-mmio”) instead of the PCI device. This adds a transport driver that implements UCLASS_VIRTIO for virtio over mmio.

virtio: pci: Allow exclusion of legacy driver Add a new config to control whether the driver for legacy virtio PCI devices is included in the build. VIRTIO_PCI_LEGACY is included by default when VIRTIO_PCI is selected, but it can also be independently toggled.
