2013-12-24Remove PCI_ROM_RUN optionVladimir Serbinenko
The main purpose of option rom is to supply int* handlers. But supplying those is outside of coreboot scope and if someone needs those they should run SeaBIOS anyway which runs the option roms wonderfully. Running VGA oprom is kept because they're needed to init graphics. This patch still keeps the options to include the option roms to make them available to SeaBIOS.

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: Fix an issue clearing port change status bitsDuncan Laurie

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.

It had numerous errors and was really painful anyway since it was just a bunch of opaque magic numbers that made bugs non-obvious. - Clock source bitfields for peripherals handled in the switch statement are 3 bits, not 4. Some divider values are 3 bits, some are 4. The earlier code always assumed 4 bits for both which included reserved bits in many cases. - UART source clock and divider shift values were wrong. - PWM clock divider was being read from the wrong register. - SPI3 divider value was being read from the wrong register. - There was a really confusing calculation for SDMMC0 and SDMMC2 clock rates, but it was never actually used since the switch statement never handled PERIPH_ID_SDMMC{0,2} and would thus return if they were ever passed into this function.

2013-12-21Pit: graphicsRonald G. Minnich
This includes the new dp code, which is better, and the fimd code, which is changed and improved. We took the chance to remove un-needed files, and also to remove some foolish u-boot habits, but not all of them. That will take time. With these changes we get graphics. Since the only mainboards we have with 16 bit graphics are 5:6:5, adjust edid.c to just use that format. If at some future time we need 4:4:4, which seems unlikely, we'll need to add a function to adjust the lb_framebuffer. Note that you can't just divine this from the EDID, as the graphics pipe format need not match the actual final format used. The EDID reading works. We've been requested to support hard-coded EDIDs and that will come in the next revision. Currently the hard-coded EDID is ignored for testing.

2013-12-21kirby: pit: Fix up wakeup_need_resetGabe Black
In a previous commit the contents of wakeup_need_reset were removed because the GPIO it referred to wasn't connected to anything on pit. I didn't realize at that time that that could have been because we hadn't tried getting suspend/resume working on pit and hadn't updated that file. On snow, the GPIO is the recovery mode pin. This change updates pit to have the right GPIO, kirby to read that GPIO, and makes the comments for both pit and kirby more explicit and spells out the fact that this is the recovery mode GPIO. Having a check here at all may still be a holdover from snow that isn't applicable to pit or kirby, but since there is a parallel as far as the recovery mode GPIO we might as well make them match while waiting for more information.
