John Baldwin 589d604bf9 Disable decoding of BARs by devices before we trash the value in the BAR ... by writing all 1's to it to determine its length. This fixes issues with MCFG on at least some machines where a trashed BAR claimed subsequent attempts at PCI config transactions because the addresses in the MCFG window fell in the decoding range of the BAR. In general it is a bad idea to leave the BARs enabled while we are frobbing with them in this manner. Sleuthing by: tegge MFC after: 1 week		2009-01-16 22:22:30 +00:00
