This patch, based on virtio PCI driver, adds support for memory mapped (platform) virtio device. This should allow environments like qemu to use virtio-based block & network devices even on platforms without PCI support. One can define and register a platform device which resources will describe memory mapped control registers and "mailbox" interrupt. Such device can be also instantiated using the Device Tree node with compatible property equal "virtio,mmio".

* virtio memory mapped device
|
|
|
|
See http://ozlabs.org/~rusty/virtio-spec/ for more details.
|
|
|
|
Required properties:
|
|
|
|
- compatible: "virtio,mmio" compatibility string
|
|
- reg: control registers base address and size including configuration space
|
|
- interrupts: interrupt generated by the device
|
|
|
|
Example:
|
|
|
|
virtio_block@3000 {
|
|
compatible = "virtio,mmio";
|
|
reg = <0x3000 0x100>;
|
|
interrupts = <41>;
|
|
}
