Hi,

When I use a pass-though device, I get the following error.

Overlapped to device[00:03.0][Region:0][Address:0000c000h][Size:00000100h]
pt_bar_mapping: ptdev[00:06.0][Region:0][Address:0000c000h][Size:00000100h] is overlapped.

It's caused by reinitializing pci resources.
rombios should not initialize pci because hvmloader already setup pci.
If pci devices are re-initialized, their configurations may corrupt.
