2013-08-09intel/sandybridge intel/bd82x6x: remove explicit pcie config accessesKyösti Mälkki
Now that MMCONF_SUPPORT_DEFAULT is enabled by default remove the pcie explicit accesses. The default config accesses use MMIO.

2012-11-12Add bd82x6x mainboards ASPM overrides.Marc Jones
The Intel PCH can override the ASPM settings via the MPC2 register. Add a chip override for F0-F7. Mainboards may implement this as needed. This also fixes the final PM setup being done too early. It was being done prior to the PCIe ASPM setup, which happens in the bridge scan.

2012-05-01Fix issue with PCIe power management setupDuncan Laurie
The current early PM setup that attempts to configure dynamic clock gating relies on PCIe functions to be enabled that may not be. Instead of reading port 0 or 4 directly to determine the link width use the register that refelects the soft strapping options as this will always be available. Also add a clear register assignment and break for port 0 in the switch statement instead of falling through to port 4 as that could end up setting the slot power limit based on port 4 values instead of based on port 0. register 0xE1=0x3f and all other root ports should have 0xE1=0x03. When port 0 and 4 are disabled they will have 0xE1=0x3C before being disabled by the pch enable handler.
