2014-07-05spi: Change spi_xfer to work in units of bytes instead of bits.Gabe Black
Whenever spi_xfer is called and whenver it's implemented, the natural unit for the amount of data being transfered is bytes. The API expected things to be expressed in bits, however, which led to a lot of multiplying and dividing by eight, and checkes to make sure things were multiples of eight. All of that can now be removed. BUG=None TEST=Built and booted on link, falco, peach_pit and nyan and looked for SPI errors in the firmware log. Built for rambi.

2014-07-04intel/lynxpoint: Make inclusion of Intel ME optionalPaul Menzel
Current build configuration always wants to include an Intel Management Engine (ME) firmware (`me.bin`) on Intel Lynx Point systems. However, we can have a working coreboot without it, as long as the factory delivered ME firmware is kept untouched in the flash ROM. So let the user decide if a ME firmware will be included in the build by introducing the Kconfig option `HAVE_ME_BIN`. The same was done in commit 99fd30e4 (sandybridge: Make inclusion of me.bin optional) [1] for Intel Sandy Bridge (BD82x6x).

2014-07-04intel/lynxpoint: Allow building without IFD (descripter.bin)Paul Menzel
On newer Intel systems, like Intel Lynx Point, the flash ROM is shared between the host processor (BIOS), its Management Engine (ME) and an integrated Ethernet controller (GbE). The layout of the flash ROM (and other information) is kept in the so called Intel Firmware Descriptor (IFD). If we only want to build coreboot to update the BIOS section, all we need is the flash layout. So add the option to specify the flash layout in the mainboard’s Kconfig, and thus, to build without the real IFD. However, with such a build, one has to make sure that the IFD section on the flash ROM will not be written over (nor any other section that has not been included by coreboot). A patch to write selected sections of a flash ROM with IFD has been sent to the flashrom mailing list [2]. The same was done in commit a15cd66b [1] (sandybridge: Make build possible without descriptor.bin) for Intel Sandy Bridge (BD82x6x).

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.

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.

Additionally add back the code that resets disconnected USB3 ports on the way into suspend (as stated in the BWG) but take care to clear the PME status bit so we don't immediately wake. suspend/resume with USB3 devices 1) suspend with no devices, plug in while suspended, then resume and verify that the devices are detected 2) suspend with USB3 devices inserted, then suspend and resume and verify that the devices are detected 3) suspend with USB3 devices inserted, then remove the devices while suspended, resume and ensure they can be detected again when inserted after resume Change-Id: Ic7e8d375dfe645cf0dc1f041c3a3d09d0ead1a51 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/65733 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Commit-Queue: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4473 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>
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. A kernel compiled with CONFIG_ACPI_DEBUG=y and module parameters acpi.debug_layer=0x7f acpi.debug_level=0x2f can be used to see what ACPI methods are executed: kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS3] (Node ffff8801000a7f50) kernel: ACPI: Preparing to enter system sleep state S3 ... kernel: ACPI: Waking up from system sleep state S3 kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff8801000a7f28) kernel: xhci_hcd 0000:00:14.0: power state changed by ACPI to D0 Change-Id: Ic64040eb4dd1947a1e2f0ee253a64be683e0ec70 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> meld with s3d Change-Id: Ic6789720c4efe661dcb03a4afce8d88115854472 Reviewed-on: https://gerrit.chromium.org/gerrit/63916 Tested-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Commit-Queue: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/4409 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>

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.

2013-12-12HDA: Enable Mini-HDA and fix up PCH-HDA initDuncan Laurie
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! With a basic kernel patch to add 0x0a0c device ID to HDA driver and with HDMI cable connected it is much happier: snd_hda_intel 0000:00:03.0: irq 60 for MSI/MSI-X input: HDA Intel MID HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input9 snd_hda_intel 0000:00:1b.0: irq 61 for MSI/MSI-X input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1b.0/sound/card1/input10 input: HDA Intel PCH Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card1/input11 Change-Id: Ifa587984be4fc2801704a0368b9cdf8379c2450e Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/59336 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4318 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

Ensure the driver loads at boot: gpiochip_find_base: found new base at 162 gpiochip_add: registered GPIOs 162 to 255 on device: INT33C7:00 Also ensure the driver is visible in sysfs: $ cat /sys/devices/platform/INT33C7:00/gpio/gpiochip162/label INT33C7:00 Change-Id: I9f79c008f88da9b67ed1cdfdb9d3a581ce8f05ff Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/50215 Reviewed-on: http://review.coreboot.org/4158 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
