* Name: up_fbinitialize
* Name: virtio_gpu_fb_register
*
* Description:
* Initialize the framebuffer video hardware associated with the display.
*
* Input Parameters:
* display - In the case of hardware with multiple displays, this
* specifies the display. Normally this is zero.
* display - The display number for the case of boards supporting multiple
* displays or for hardware that supports multiple
* layers (each layer is consider a display). Typically zero.
*
* Returned Value:
* Zero is returned on success; a negated errno value is returned on any
* Zero (OK) is returned success; a negated errno value is returned on any
* failure.

* Returned Value:
* A non-NULL pointer to the frame buffer access structure is returned on
