2014-02-12lynxpoint: Do not put SerialIO devices into D3Hot in ACPI modeDuncan Laurie
Remove the bit of code that was putting the SerialIO devices into D3Hot state when they are switched from PCI to ACPI mode. Instead, add the appropriate ACPI Methods to allow the kernel to control the power state of the device. The problem seems to be that if the device is put in D3Hot state before it is switched from PCI to ACPI mode then it does not properly export its PCI configuration space and cannot be woken back up. Adding the ACPI Methods for _PS0/_PS3 allows the kernel to transition the device into D0 state only when it is necessary to communicate with the device, then put it back into D3Hot state.

2014-02-04AMD cimx/sb800: Set SPI frequency and prefetchKyösti Mälkki
Broken with/since commit d1cb0eec. Original intention was to set the frequency for 'Fast Read' command in bits 15..14, and enable 'Fast Read' command. Modified register contains SPI frequency for 'Normal Read' command in bits 13..12. Default for this is 11b for 16.5 MHz. Existing code unintentionally clears these bits, increasing SPI frequency to 66MHz for 'Normal Read' command. This is above specifications for many common SPI flash components and also makes flashrom older than 0.9.7-r1750 to operate unreliably on read/write/erase for these platforms.

2013-12-21lynxpoint: XHCI: Don't put device in D3 in _PS0 MethodDuncan Laurie
The end of the _PS0 method that is supposed to transition the XHCI device to D0 state is instead putting it in D3 state. This triggers a PME_B0 GPE which causes a Notify to the XHCI ACPI Device in the kernel and that increments the wakeup counter and causes aborted suspends. Instead if we just leave the device in D0 where it should be after executing this function then the PME_B0 is not generated and the kernel does not see a wakeup on XHCI. Similarly I changed the _PS3 method to always put the device in D3 at the end of the method, rather than depending on the state to be D3 at the start. Before this change the kernel would see the following sequence when trying to suspend when the XHCI controller is in D3cold: kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff88017802bf28) kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [XHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802bc30 kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [EHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802b8e8 kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [HDEF] (Device) Value 0x02 (Device Wake) Node ffff88017802b1b8 kernel: xhci_hcd 0000:00:14.0: power state changed by ACPI to D0 kernel: xhci_hcd 0000:00:14.0: PME# disabled kernel: xhci_hcd 0000:00:14.0: enabling bus mastering kernel: xhci_hcd 0000:00:14.0: setting latency timer to 64 kernel: PM: Wakeup pending, aborting suspend kernel: last active wakeup source: 0000:00:14.0 Now it does not get a notification (due to PME_B0) when going to D0 on the way into suspend.

2013-12-21lynxpoint: XHCI: Advertise D3 as lowest wake stateDuncan Laurie
The recommended value in docs is D2, but lynxpoint XHCI does not even support D2 state which causes the kernel to think this device cannot be used as a wake source: kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI kernel: ACPI: Device does not support D2 kernel: xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI Additionally this means the kernel will never put the device into D3 state by itself. There is SMI code that will put the device into D3 before suspend so advertising D3 here should be correct. With this change the kernel will put the controller into D3 on suspend and back to D0 on resume, including executing the ACPI methods for _PS0/_PS3 that contain chipset specific workarounds. In addition add a _PSC method to directly return the D state from the device registers. With ALL USB devices removed the XHCI controller goes into D3 state and the kernel can have a hard time determining the state of the device at boot.

2013-12-21lynxpoint: Route all USB ports to XHCI in finalize stepDuncan Laurie
This commit adds a new Kconfig option for the LynxPoint southbridge that will have coreboot route all of the USB ports to the XHCI controller in the finalize step (i.e. after the bootloader) and disable the EHCI controller(s). Additionally when doing this the XHCI USB3 ports need to be put into an expected state on resume in order to make the kernel state machine happy. Part of this could also be done in depthcharge but there are also some resume-time steps required so it makes sense to keep it all together in coreboot. This can theoretically save ~100mW at runtime. Verify that the EHCI controller is not found in Linux and that booting from USB still works.

The SystemAgent contains a mini-hd audio controller at PCI 0:3.0 which uses the same verb table init sequence as the southbridge. In order to avoid two copies of the verb table loading code I separated out the HDA verb table functions into a file that can be re-used and then added a minihd driver to the haswell northbridge. The minihd verb table is the same across devices so it can live within the minihd driver rather than needing to be specified in each separate mainboard. I also fixed up the driver for lynxpoint HDA by following the reference code. Without HDMI cable plugged in driver does not find any codec, and it does not seem to re-probe when HDMI is connected. We may be missing kernel patches for this. hda-intel 0000:00:03.0: no codecs found!

In order to report whether coreboot enabled a SerialIO device in ACPI mode we had been relying on reading NVS in the _STA method for the SerialIO device. The ACPI _STA method has restrictions on what it can access and is unable to access OperationRegions outside its scope which means it should not be trying to read NVS. 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. Attempt to use lpt-clk driver to probe the device clocks for SerialIO devices and see that the kernel does not complain about accessing the GNVS region.
