2013-12-05lynxpoint: disable pcie devices based on configAaron Durbin
PCIe Root Ports should be disabled based on pin ownership and the strapping configuration. Implement this logic for LynxPoint. The chip_ops->enable_dev() path is no longer used. Instead the PCIe driver handles the enabling and disabling of devices. This allows for having an empty or incomplete device tree since those "allocated" devices do not travel through the chip_ops->enable_dev() path. The coalescing was tested to be working properly, however not all configurations were tested.

This change adds a new SSDT to the ACPI tables and fills it with constants that indicate whether or not a device is enabled in ACPI mode. The ACPI code is changed to read these variables from the SSDT and use that instead of trying to query a variable in NVS.

The _OSC method is used to tell the OS what capabilities it can take control over from the firmware. This method is described in chapter 6.2.9 of the ACPI spec v3.0. The method takes 4 inputs (UUID, Rev ID, Input Count, and Capabilities Buffer) and returns a Capabilites Buffer the same size as the input Buffer. This Buffer is generally 3 Dwords long consisting of an Errors Dword, a Supported Capabilities Dword, and a Control Dword. The OS will request control of certain capabilities and the firmware must grant or deny control of those features. We do not want to have control over anything so let the OS control as much as it can. The _OSC method is required for PCIe devices. During Linux boot, an error is logged to dmesg if _OSC is not found.

Adding the 'WordBusNumber' macro to the PCI0 CRES ResourceTemplate in the AMD FCH ACPI code. This sets up the bus number for the PCI0 device and the secondary bus number in the CRS method. This change came in response to a 'dmesg' error which states: '[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS' By adding the 'WordBusNumber' macro, ACPI can set up a valid range for the PCIe downstream busses, thereby relieving the Linux kernel from "guessing" the valid range based off _BBN or assuming [0-0xFF]. The Linux kernel code that checks this bus range is in `drivers/acpi/pci_root.c`. PCI busses can have up to 256 secondary busses connected to them via a PCI-PCI bridge. However, these busses do not have to be sequentially numbered, so leaving out a section of the range (eg. allowing [0-0x7F]) will unnecessarily restrict the downstream busses.

2013-08-05AMD Hudson/Yangtze: Enable support for SATA port multipliersBruce Griffith
This patch sets a bit in the Yangtze southbridge to enable the extra protocol necessary to handle port multiplier chips. This has been turned on during most of Kabini development without any notable impact. Olive Hill has an optional daughter board that incorporates Silicon Image Steel Vines chips. This change has been tested with and without the daughter board. This change can be regression tested using any Hudson-based motherboard, although it has no impact on boards with discreet Hudson/Bolton southbridges. This was tested for impact on SATA performance in the absence of a port multiplier using the IOZone benchmarks within the Phoronix Test Suite. A SATA 3 hard drive (6.0 Gbps) and an SSD were connected to the ports on Olive Hill without using the port multiplier card. The test results contained more run-to-run variation within the same configuration than was seen in the aggregate results comparing the interface with and without the port multiplier protocol additions. In other words, the test had less accuracy than the impact caused by turning on port multiplier support.

2013-07-16AMD Fam15tn: Split DSDT into common sectionsSteve Goodrich
Split the Parmer, Family 15tn, and Hudson DSDT into groups. This splits the DSDT table into includable ASL files which carry details specific to the Family 15tn APU, the Parmer platform, and the Hudson FCH. The dsdt.asl file in the mainboard directory contains only #include references to the appropriate files. Initially, this split was done by moving each piece of functionality into its own file (e.g. IRQ routing and mapping, processor tree, sleep states and sleep methods, etc.) and those pieces were #included in dsdt.asl to ensure an exact match (via acpidump/acpixtract/iasl -d) with the extant version of the table. Once the new tables were found to exactly match the existing tables, the pieces were rearranged into reasonable groups (e.g. fch.asl, northbridge.asl, pci_int.asl, etc.). Some include files have no content but are left as a template for other platforms and as placeholders for completing the ACPI implementation for Parmer (e.g. thermal.asl, superio.asl, ide.asl, sata.asl, etc.).
