Older libpci versions (e.g
2.2.8, as it's default on current FreeBSD 7.2) don't properly fill the base_addr[0] struct member, so revert back to an explicit pci_read_long() call, otherwise detection of PCI devices and their base address will fail with strange error messages. Thanks Idwer Vollering <> for reporting and testing. Corresponding to flashrom svn r518. Signed-off-by: Uwe Hermann <> Acked-by: Uwe Hermann <>
