[PATCH v1 0/4] PCI/VGA: Improve the default VGA device selection
From: Sui Jingfeng <suijingfeng at loongson.cn>
Currently, the default VGA device selection is not perfect. Potential
problems are:
1) This function is a no-op on non-x86 architectures.
2) It does not take the PCI Bar may get relocated into consideration.
3) It is not effective for the PCI device without a dedicated VRAM Bar.
4) It is device-agnostic, thus it has to waste the effort to
