As the PCIe specification recommend reading the Vendor ID register to determine if a Function is present, read the Vendor ID of a non-existent Function must not result in system error, so we'd better make the first CFG read to Vendor ID instead of Header Type register in the PCIe enumeration.

Simon, do we need fix the non-DM version or adding new "capability" to the non-DM drivers? I guess the answer is no and we should set some deadline for PCI DM conversion too?
We should not fix or add new features to non-DM PCI. No one should be using it at this point.
I agree about the deadline. Do you want to send a patch?
Actually I am not sure how to send a patch for such kind of deadline stuff :-) Please go ahead.
Regards, Bin
