Can't Access PCIe Network IO Resource at early POST

Question:
Can't access PCIe network IO resource at early POST issue.

Solution:
The PCI command register set to 0x07 and assign IO resource forPCIe network device. It also needs to set the PCI command register set to 0x07 on PCIe bridge.

問題：
最近有遇到一個要存取掛在PCIe Bridge底下的PCIe網卡設定問題，狀況是無法在early POST時存取到PCIe網卡底下的IO resource。

解決方案：
PCIe網卡的PCI command register設成0x07以及指派IO resource外，注意也需要把PCIe Bridge的PCI command register設成0x07。
