2014-06-14amd/agesa,cimx: Rename ACPI OS detection methodsEdward O'Callaghan
Try to 'standardize' the otherwise peculiar method naming to be somewhat more in-line with other ACPI implementations. This makes it easier to compare with vendor DSDT dumps for example.

2014-04-13cimx/sb800 boards: Don't require ide.asl on boards without IDEEdward O'Callaghan
Not all boards which use the AMD cimx/sb800 southbridge have IDE. However, the southbridge's asl included an 'ide.asl' file which had to be present in $(mainboard_dir)/acpi. Address this issue by including ide.asl only in boards which have IDE, and remove it from all other cimx/sb800 boards.

2013-03-17Lippert Fam14 DSDT: Remove INI method from AZHD deviceMike Loptien
I am removing the _INI method from the AZHD device because it does not seem to do anything and causes errors in the FWTS[1] (Firmware Test Suite) test 'method'. The INI method performs device specific initialization and is run when OSPM loads a description table. It must only access OperationRegions that have been indicated as available by the _REG (Region) method. We do not have a _REG method and during my testing, I added a REG method but it did not seem to make a difference in the PCI register space. The bit fields defined as NSDI (Disable No Snoop), NSDO (Disable No Snoop Override), and NSEN (Enable No Snoop Request) do not ever get written from their default values. And writing to these bit fields does not seem to be necessary because I did not notice any change in audio functionality. In an effort to clean up as many FWTS errors as possible, I propose removing this method altogether. I have seen no change in operation (audio works with and without this method) and there does not seem to be any change in lspci or dmesg. FWTS information can be found here: [1]: https://wiki.ubuntu.com/Kernel/Reference/fwts This is the same change as made to Persimmon in Change-ID If8d86f: http://review.coreboot.org/#/c/2726/ Change-Id: Iff594d4a3493531561eb25d1cceeb97bcefde424 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/2743 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2013-03-17Lippert Fam14 DSDT: Add secondary bus range to PCI0Mike Loptien
Adding the 'WordBusNumber' macro to the PCI0 CRES ResourceTemplate in the Persimmon DSDT. 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. This is the same change as made to Persimmon with change-id I44f22: http://review.coreboot.org/#/c/2592/ Change-Id: Ie36b60973c6a5f9076bb55c8f451532711a2f8a8 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/2737 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2013-03-17Lippert Fam14 DSDT: Add OSC methodMike Loptien
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 and dmesg checks for its existence and issues an error if it is not found.

Step 2: change the Persimmon code to adapt it to the new board's hardware. The FrontRunner-AF is a PC/104+ form factor embedded board: - AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU - DDR3 SO-DIMM socket (1.5 or 1.35V) - VGA and LVDS (via Analogix ANX3110) - AMD A55E (Hudson-E1) southbridge - 6x USB 2.0 - 1x SATA, 1x CFast socket - HD Audio (via Realtek ALC886) - PCI and ISA (via ITE IT8888) - NEC uPD78F0532 microcontroller on I2C ("SEMA") - Intel I210 GbE (on APU PCIe x1) - SMSC SCH3112 SIO - PS/2 - 2x RS232/485 - 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS) http://www.adlinktech.com/PD/web/PD_detail.php?pid=1131 Change-Id: Id55f89d224ad669b351c36128b12299802b721ba Signed-off-by: Jens Rottmann <JRottmann@LiPPERTembedded.de> Reviewed-on: http://review.coreboot.org/2553 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
2013-03-02LiPPERT FrontRunner-AF [1/2]: create board by forking AMD PersimmonJens Rottmann
Step 1: copy all files unmodified from Persimmon. This makes it much easier later to see how the two boards actually and deliberately differ when porting bugfixes from one to the other. Git's copy detection is imperfect (and slow).
