Removing `-Wno-unused-but-set-variable` from `CFLAGS` the build for QEMU Q35 and Roda RK9, both using the Intel 82801Ix southbridge, fail with the following error. src/southbridge/intel/i82801ix/lpc.c: In function 'i82801ix_enable_apic': src/southbridge/intel/i82801ix/lpc.c:45:5: error: variable 'dummy' set but not used [-Werror=unused-but-set-variable] cc1: all warnings being treated as errors Removing `dummy` should be safe as GCC probably optimizes it away before anyway. That no dummy variable is used for an RCBA [1] access in Intel Lynx Point supports that this can be dropped safely.

The main usbdebug file lib/usbdebug.c was removed from romstage build with commit f8bf5a10 but the chipset-specific parts were not, leading to unresolved symbol errors for AMD platforms.

With USBDEBUG selected, PCI EHCI controller's device_operations .read_resources is replaced with pci_ehci_read_resources() call, which in turn will replace the device_operations .set_resources call. The replacement for .set_resources reconfigures usbdebug driver side, and calls the original .set_resources to configure hardware side.

2013-06-24sandybridge: Make build possible without descriptor.binNico Huber
On newer Intel systems, the flash ROM is shared between the host processor (BIOS), it's 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. This patch adds 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 won't be written over (nor any other section that hasn't been included by coreboot). A patch to write selected sections of a flash ROM with IFD has been sent to the flashrom mailing list [1].

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.

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.

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.

2013-03-22romstage: 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 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. 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.

The PMBASE, GPIOBASE, and LPC generic I/O decode ranges are checked against the default claimed range. If those ranges overlap or fall outside of the default range then those resources are added. The MMIO range reservations consist of claiming everything from the I/O APIC to 4GiB. The RCBA and the LPC Generic Memory range register are then conditionally added if they fall outside of the default MMIO range.
