2013-05-10Get rid of a number of __GNUC__ checksStefan Reinauer
In the process of streamlining coreboot code and getting rid of unneeded ifdefs, drop a number of unneeded checks for the GNU C compiler. This also cleans up x86emu/types.h significantly by dropping all the duplicate types in there.

2013-05-01AMD Hudson A55E: Remove GEC firmware blob kconfig promptBruce Griffith
The "gigabit ethernet controller" (GEC) block was added to AMD Hudson A55E to integrate ethernet capabilities into an AMD southbridge. The GEC is designed to work with B50610 and B50610M gigabit PHY chips from Broadcom. These parts may not be generally available in small quantities for embedded development. The GEC block requires an opaque firmware blob to function. The GEC blob is controlled by AMD and Broadcom and is not available from coreboot.org. This change removes GEC support from AMD Parmer and AMD Thatcher mainboards since these boards do not have the Broadcom PHY. AMD has requested that the GEC be hidden for Hudson FCH since the PHY parts are not generally available. This Kconfig option can make it appear that this is a viable and supported way to add Ethernet to an embedded board. It is possible to use the Hudson GEC block with other PHYs, but this requires development of a custom GEC blob and a custom Ethernet driver. A custom GEC blob has been developed for a Micrel PHY, but there is no accompanying driver.

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.

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.

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.

2013-03-21haswell/lynxpoint: Use new PCH/PM helper functionsDuncan Laurie
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.

This adds an \ISLP() method that checks the chipset LPC device ID to see if it is -LP or -H. It also increases the PM base reservation to 256 bytes and moves both GPIO and PM base to above 0x1000 on -LP chipsets.

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. This savings is observed using cbmem.py after performing warm reboots and looking at TS_SELFBOOT_JUMP (99) entries. This is booting with a depthcharge payload whose payload file fits within the SMM_DEFAULT_SIZE (0x10000 bytes). Datapoints with TS_LOAD_PAYLOAD (90) & TS_SELFBOOT_JUMP (99) cbmem entries: Baseline Alt -------- -------- 90:3,859,310 (473) 90:3,863,647 (454) 99:3,989,578 (130,268) 99:3,888,709 (25,062) 90:3,899,450 (477) 90:3,860,926 (463) 99:4,029,459 (130,008) 99:3,890,583 (29,657) 90:3,834,600 (466) 90:3,890,564 (465) 99:3,964,535 (129,934) 99:3,920,213 (29,649) Booted baskingridge many times and observed 100ms reduction in TS_SELFBOOT_JUMP times (time to load payload).

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.
