Subject: x86: ivybridge: Use driver model PCI API in bd82x6x.c
X-Git-Tag: v2016.03-rc1~106
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1a9dd221c679705b131b160b6342f218ea71bd96;p=oweals%2Fu-boot.git

x86: ivybridge: Use driver model PCI API in bd82x6x.c

Adjust most of the remaining functions in this file to use the driver model
PCI API. The one remaining function is bridge_silicon_revision() which will
need a little more work.
