astfb* at pci?

The astfb driver supports the frame buffer set up by firmware on systems with an Aspeed Baseboard Management Controller (BMC).

The astfb driver interfaces the frame buffer with the wscons(4) console framework. It does not provide direct device driver entry points but makes its functions available via the internal wsdisplay(4) interface.
