From a2faddf7d38e4651ce6654c62b668ab02b909b58 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Sat, 5 Jan 2013 23:52:45 +0000 Subject: Decouple BAR reading from pci device init, handle errors gracefully MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pcidev_init() now returns struct pci_device * instead of a BAR stored in PCI config space. This allows for real error checking instead of having exit(1) everywhere in pcidev.c. Thanks to Niklas Söderlund for coming up with the original error handling patch which was slightly modified and folded into this patch. Move the declaration of struct pci_device in programmer.h before the first user. Corresponding to flashrom svn r1644.
