-/**
- * @brief Read resources for AGP aperture
- *
- * @param 
- *
- * There is only one AGP aperture resource needed. The resoruce is added to
- * the northbridge of BSP.
- *
- * The same trick can be used to augment legacy VGA resources which can
- * be detect by generic pci reousrce allocator for VGA devices.
- * BAD: it is more tricky than I think, the resource allocation code is
- * implemented in a way to NOT DOING legacy VGA resource allcation on
- * purpose :-(.
