This was written for developing 8822BE. And it was not tested at that moment so I was not sure if it can be removed. Now many test item has been tested, it seems that the configuration parsing code is no more needed. And I see that pci_set_master() will enter D0. So it can be removed. Thanks. Yan-Hsuan
