I play some trick. Rom_address(src/devices/pci_rom.c) is manually set to 0xfff80000 if class is detected as 3 and subclass is detected as 0 (VGA device). The boot log shows on a monitor, too. The attached is the boot log. But it is against the purpose of PCI, hardware independence, I still need a complete solution. Thank you for your support these days, Mr Lu.
PCI: 00:0c.0 init
rom address for PCI: 00:0c.0 = fc220000
BTDC: device class = 0
BTDC: device class = 3
BTDC: set rom_address manually
copying VGA ROM Image from 0xfff80000 to 0xc0000, 0x9000 bytes
un-inited int vector

it looks familiar about mmio resource allocation is not right.
It seems i fixed it some time ago, but it is still in my tree.
Let me compare public tree with my own tree this weekend, or I will send your my partial tree to you.
