2013-04-15Fam14 DSDT: Also return for unrecognized UUID in _OSCMike Loptien
Fixing warnings introduced by the following patches: http://review.coreboot.org/#/c/2684/ http://review.coreboot.org/#/c/2739/ http://review.coreboot.org/#/c/2714/ These patches were meant to fix the dmesg warning about the OSC method not granting control appropriately. These patches then introduced warnings during the coreboot build process which were missed during the patch submission process. These warnings are below: Intel ACPI Component Architecture ASL Optimizing Compiler version 20100528 [Oct 15 2010] Copyright (c) 2000 - 2010 Intel Corporation Supports ACPI Specification Revision 4.0a dsdt.ramstage.asl 1143: Method(_OSC,4) Warning 1088 - ^ Not all control paths return a value (_OSC) dsdt.ramstage.asl 1143: Method(_OSC,4) Warning 1081 - ^ Reserved method must return a value (Buffer required for _OSC) ASL Input: dsdt.ramstage.asl - 1724 lines, 34917 bytes, 889 keywords AML Output: dsdt.ramstage.aml - 10470 bytes, 409 named objects, 480 executable opcodes Compilation complete. 0 Errors, 2 Warnings, 0 Remarks, 494 Optimizations This patch gives the following compilation status: Intel ACPI Component Architecture ASL Optimizing Compiler version 20100528 [Oct 1 2012] Copyright (c) 2000 - 2010 Intel Corporation Supports ACPI Specification Revision 4.0a ASL Input: dsdt.ramstage.asl - 1732 lines, 33295 bytes, 941 keywords AML Output: dsdt.ramstage.aml - 10152 bytes, 406 named objects, 535 executable opcodes Compilation complete. 0 Errors, 0 Warnings, 0 Remarks, 432 Optimizations The fix is simply adding an Else statement to the If which checks for the proper UUID.

2013-04-11Persimmon/Fam14/SB800 DSDT: Split into common areasMike Loptien
Split the Persimmon DSDT into common code areas. For example, split the Southbridge specific code into the Southbridge directory and CPU specific code into the CPU directory. Also adding the superio.asl file to the Persimmon DSDT tree. This file is empty for the moment but will be necessary in the future. I have also emptied the thermal.asl file in the mainboard directory because it does not seem to perform as intended (fan control does not change when it is brought back into the code base) and it has been inside a '#if 0' statement for a long time. Removing it until it is decided that it is actually necessary. This change was verified in three different ways: 1. Visual comparison of the compiled DSDT pulled from the Persimmon after booting into Linux using the ACPI tools acpidump, acpixtract, and iasl. The comparison was done between the DSDT before and after doing the split work. This test is somewhat difficult considering the expanse of the changes. Blocks of code have been moved, and others changed. 2. Linux logs were dumped before and after the DSDT split. Logs dumped and compared include dmesg and lspci -tv. Neither log changed significantly between the two compare points. 3. The test suite FWTS was run on the Coreboot build both before and after doing the DSDT split with the command 'sudo fwts -b -P -u'. The flag -b specifies all batch jobs, -P specifies all power tests, and -u specifies utilities. Interactive jobs were not run as most of them consist of laptop checks. Again, there were no significant changes between the two endpoints. These tests lead me to believe that there was no change in the functionality of the ACPI tables apart from what is known and expected. This patch is the first of a series of patches to split the DSDT. The ASRock patch was merged before this one and breaks the ASROCK E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/). Please be aware of this dependency when pulling these patches. Other patches that depend on this patch are 'AMD Fam14: Split out the AMD Fam14 DSDT' (http://review.coreboot.org/#/c/3051/) and 'Fam14 DSDT: Also return for unrecognized UUID in _OSC' (http://review.coreboot.org/#/c/3052/) Change-Id: I53ff59909cceb30a08e8eab3d59b30b97c802726 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/3048 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martin.roth@se-eng.com>

2013-04-01lynxpoint: Move ACPI NVS into separate CBMEM tableDuncan Laurie
The ACPI NVS region was setup in place and there was a CBMEM table that pointed to it. In order to be able to use NVS earlier the CBMEM region is allocated for NVS itself during the LPC device init and the ACPI tables point to it in CBMEM. The current cbmem region is renamed to ACPI_GNVS_PTR to indicate that it is really a pointer to the GNVS and does not actually contain the GNVS.

2013-04-01lynxpoint: Basic configuration of SerialIO devicesDuncan Laurie
This adds configuration of SerialIO devices in the Lynxpoint-LP chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers. There is assorted magic setup necessary for the devices and while it is similar for each device there are subtle differences in some register settings. These devices must be put into "ACPI Mode" in order to take advantage of S0ix. When in ACPI mode the allocated PCI BARs must be passed to ACPI so it can be relayed to the OS. When the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS and then updated and returned when the OS calls _CRS. Note that is is not entirely complete yet. We need to update the IASL compiler in our build environment to support ACPI 5.0 in order to be able to pass the FixedDMA entries to the kernel. There are also no ACPI methods defined yet to do D0->D3->D0 transitions for actually entering/exiting S0ix states. This is hard to test right now because our kernel does not support any of these devices in ACPI mode. I was able to build and test the upstream bleeding-edge branch of the linux-pm git tree. With that tree I was able to enumerate and load the driver for the DesignWare I2C driver and attempt to probe the I2C bus -- although there are no devices attatched. I am also able to see the resources from ACPI in /proc/iomem get reserved properly in the kernel.

The new enable_pm1() function was doing 2 things wrong: 1. It was doing a RMW of the pm1 register. This means we were keeping around the enables from the OS during S3 resume. This is bad in the face of the RTC alarm waking us up because it would cause an infinite stream of SMIs. 2. The register size of PM1_EN is 16-bits. However, the previous implementation was accessing it as a 32-bit register. The PM1 enables should only be set to what we expect to handle in the firmware before the OS changes to ACPI mode.

2013-04-01lynxpoint: split clearing and enabling of smmAaron Durbin
Previously southbridge_smm_init() was provided that did both the clearing of the SMM state and enabling SMIs. This is troublesome in how haswell machines bring up the APs. The BSP enters SMM once to determine if parallel SMM relocation is possible. If it is possible the BSP releases the APs to do SMM relocation. Normally, after the APs complete the SMM relocation, the BSP would then re-enter the relocation handler to relocate its own SMM space. However, because SMIs were previously enabled it is possible for an SMI event to occur before the APs are complete or have entered the relocation handler. This is bad because the BSP will turn off parallel SMM save state. Additionally, this is a problem because the relocation handler is not written to handle regular SMIs which can cause an SMI storm which effectively looks like a hung machine. Correct these issues by turning on SMIs after all the SMM relocation has occurred.

2013-04-01AMD hudson & SB800 - Fix issues with mawkMartin Roth
When calculating the offsets of the various binary blobs within the coreboot.rom file, we noticed that using mawk as the awk tool instead of using gawk led to build issues. This was finally traced to the maximum value of the unsigned long variables within mawk - 0x7fff_ffff. Because we were doing calculations on values up in the 0xffxxxxxx range, these numbers would either be turned into floating point values and printed using scientific notation, or truncated at 0x7fff_ffff. To fix this, we print the values out as floating point, with no decimal digits. This works in gawk, mawk, and original-awk and as the testing below show, seems to be the best way to do this. printf %u 0xFFFFFFFF | awk '{printf("%.0f %u %d", $1 , $1 , $1 )}' mawk: 4294967295 2147483647 2147483647 original-awk: 4294967295 2147483648 4294967295 gawk: 4294967295 4294967295 4294967295 The issue of %d not matching gawk and original-awk has been reported to ubuntu. In the future, I'd recommend that whenever awk is used, a format is specified. It doesn't seem that we can count on the representation being the same between the different versions.

2013-03-22romstage: add support for vboot firmware selectionAaron Durbin
This patch implements support for vboot firmware selection. The vboot support is comprised of the following pieces: 1. vboot_loader.c - this file contains the entry point, vboot_verify_firmware(), for romstage to call in order to perform vboot selection. The loader sets up all the data for the wrapper to use. 2. vboot_wrapper.c - this file contains the implementation calling the vboot API. It calls VbInit() and VbSelectFirmware() with the data supplied by the loader. The vboot wrapper is compiled and linked as an rmodule and placed in cbfs as 'fallback/vboot'. It's loaded into memory and relocated just like the way ramstage would be. After being loaded the loader calls into wrapper. When the wrapper sees that a given piece of firmware has been selected it parses firmware component information for a predetermined number of components. Vboot result information is passed to downstream users by way of the vboot_handoff structure. This structure lives in cbmem and contains the shared data, selected firmware, VbInitParams, and parsed firwmare components. During ramstage there are only 2 changes: 1. Copy the shared vboot data from vboot_handoff to the chromeos acpi table. 2. If a firmware selection was made in romstage the boot loader component is used for the payload. Noteable Information: - no vboot path for S3. - assumes that all RW firmware contains a book keeping header for the components that comprise the signed firmware area. - As sanity check there is a limit to the number of firmware components contained in a signed firmware area. That's so that an errant value doesn't cause the size calculation to erroneously read memory it shouldn't. - RO normal path isn't supported. It's assumed that firmware will always load the verified RW on all boots but recovery. - If vboot requests memory to be cleared it is assumed that the boot loader will take care of that by looking at the out flags in VbInitParams. Built and booted. Noted firmware select worked on an image with RW firmware support. Also checked that recovery mode worked as well by choosing the RO path.

This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

This makes use of the new functions from pmutil.c that take care of the differences between -H and -LP chipsets. It also adds support for the LynxPoint-LP GPE0 register block and the SMI/SCI routing differences. The FADT is updated to report the new 256 byte GPE0 block on wtm2/wtm2 boards which is too big for the 64bit X_GPE0 address block so that part is zeroed to prevent IASL and the kernel from complaining about a mismatch. This was tested on WTM2. Unfortunately I am still unable to get an SCI delivered from the EC but I suspect that is due to a magic command needed to put the EC in ACPI mode. Instead I verified that all of the power management and GPIO registers were set to expected values. I also tested transitions into S3 and S5 from both the kernel and by pressing the power button at the developer mode screen and they all function as expected.

2013-03-19lynxpoint: Add cbfs_load_payload() implementationAaron Durbin
SPI accesses can be slow depending on the setup and the access pattern. The current SPI hardware setup to cache and prefetch. The alternative cbfs_load_payload() function takes advantage of the caching in the CPU because the ROM is cached as write protected as well as the SPI's hardware's caching/prefetching implementation. The CPU will fetch consecutive aligned cachelines which will hit the ROM as cacheline-aligned addresses. Once the payload is mirrored into RAM the segment loading can take place by reading RAM instead of ROM. With the alternative cbfs_load_payload() the boot time on a baskingridge board saves ~100ms.

2013-03-17haswell platforms: restructure romstage mainAaron Durbin
There was a mix of setup code sprinkled across the various components: southbridge code in the northbridge, etc. This commit reorganizes the code so that northbridge code doesn't initialize southbridge components. Additionally, the calling dram initialization no longer calls out to ME code. The main() function in the mainboard calls the necessary ME functions before and after dram initialization. The biggest change is the addition of an early_pch_init() function which initializes the BARs, GPIOs, and RCBA configuration. It is also responsible for reporting back to the caller if the board is being woken up from S3. The one sequence difference is that the RCBA config is performed before claling the reference code. Lastly the rcba configuration was changed to be table driven so that different board/configurations can use the same code. It should be possible to have board/configuration specific gpio and rcba configuration while reusing the romstage code.

2013-03-06AMD SB800: don't switch clock from 14 to 48 MHz for smscsuperioJens Rottmann
The power up default for the 14M_25M_48M_OSC switchable clock output ball of the SB800 chipset is 14 MHz. sb800/bootblock.c changes this to 48 MHz, which is the correct value for almost all SIOs. However, not for 'smscsuperio' (SMSC SCH311x), which needs the original 14 MHz and is not configurable for other clock speeds. A wrong SIO clock supply results in funny RS232 output (wrong bit speed) and non-working PS/2. We could switch back to 14 MHz in the mainboard's romstage.c, but then the clock frequency would change twice. The resulting short 48 MHz burst causes a handful of rubbish characters on RS232 on every boot until the SIO clock has stabilized again. This patch skips the SB800 clock switch if the SIO Kconfig requests 14 MHz. This does not affect any boards currently in the repository (yet).

2012-12-12Claim the SPI bus before writes if the IMC ROM is presentMartin Roth
The SB800 and Hudson now support adding the IMC ROM which runs from the same chip as coreboot. When the IMC is running, write or erase commands sent to the spi bus will fail, and the IMC will die. To fix this, we send a request to the IMC to stop fetching from the SPI rom while we write to it. This process (in one form or another) is required for writes to the SPI bus while the IMC is running. Because the IMC can take up to 500ms to respond every time we claim the bus, this patch tries to keep the number of times we need to do that to a minimum. We only need to claim the bus on writes, and using a counter for the semaphore allows us to call in once to claim the bus at the beginning of a number of transactions and it will stay claimed until we release it at the end of the transactions. Claim() - takes up to 500ms hit claim() - no delay erase() release() claim() - no delay write() release() Release() Change-Id: I4e003c5122a2ed47abce57ab8b92dee6aa4713ed Signed-off-by: Martin Roth <martin@se-eng.com> Reviewed-on: http://review.coreboot.org/1976 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>

The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.
