HAVE_INTEL_FIRMWARE is used to enable certain options that rely on a valid Inter Flash Descriptor to exist. It does *not* identify platforms or boards that are capable of running in descriptor mode if it's valid. Refine the help text to make this clear. Introduce a new option INTEL_DESCRIPTOR_MODE_CAPABLE that does simply declare that IFD is supported by the platform. Select this value everywhere instead of the HAVE_INTEL_FIRMWARE and default HAVE_INTEL_FIRMWARE to y if INTEL_DESCRIPTOR_MODE_CAPABLE is selected. Move the QEMU Q35 special case (deselection of HAVE_INTEL_FIRMWARE) to the mainboard directory.

2018-05-31soc/intel/broadwell: decouple PEI memory struct from coreboot headerMatt DeVillier
Recent changes to field lengths in include/memory_info.h resulted in a mismatch between the memory_info struct the MRC blob writes to and the struct used by coreboot to parse out data for the SMBIOS tables. This mismatch caused type 17 SMBIOS tables to be filled incorrectly. The solution used here is to define the memory_info struct as expected by MRC in the pei_data header, and manually copy the data field by field into the coreboot memory_info struct, observing the more restrictive lengths for the two structs. Test: build/boot google/lulu, verify SMBIOS type 17 tables correctly populated.

I finally found out why disabling the L1 sub state option did not prevent some NVMe drives from locking up in L1 substate. I expect that the disabled L1 substate initialization that coreboot does is negated because Linux might itself configure it if it finds the capability enabled on the PCIe root port. Removing the capability from the PCIe root port when L1 sub states are disabled in the configuration should fix the problem. This was not tested because it's a difficult issue to reproduce and I do not have the problematic hardware that caused it anymore.

There's an occasional issue on machines which use CMOS for their vbnv storage. The machine that just powers up from complete G3 would have had their RTC rail not held up. The contents of vbnv in CMOS could pass the crc8 though the values could be bad. In order to fix this introduce two functions: 1. vbnv_init_cmos() 2. vbnv_cmos_failed() At the start of vboot the CMOS is queried for failure. If there is a failure indicated then the vbnv data is restored from flash backup or reset to known values when there is no flash backup.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

This callback was only required for a single mainboard, and it can easily be moved to mainboard-specific code. This patch removes it from the global namespace and isolates it to the Jecht board.

2017-03-28vboot: Select SoC-specific configuration for all Chrome OS boardsJulius Werner
Some Chrome OS boards previously didn't have a hardcoded vboot configuration (e.g. STARTS_IN_BOOTBLOCK/_ROMSTAGE, SEPARATE_VERSTAGE, etc.) selected from their SoC and mainboard Kconfig files, and instead relied on the Chrome OS build system to pass in those options separately. Since there is usually only one "best" vboot configuration for a certain board and there is often board or SoC code specifically written with that configuration in mind (e.g. memlayout), these options should not be adjustable in menuconfig and instead always get selected by board and SoC Makefiles (as opposed to some external build system). (Removing MAINBOARD_HAS_CHROMEOS from Urara because vboot support for Pistachio/MIPS was never finished. Trying to enable even post-romstage vboot leads to weird compiler errors that I don't want to track down now. Let's stop pretending this board has working Chrome OS support because it never did.)

2017-03-10soc/intel/broadwell: Rework IGD's CDClk selectionNico Huber
CDClk selection was wrong in some corner cases (e.g. ULX SKUs) and, for Broadwell, never took the devicetree config into account. Rewrite the selection with the following in mind: o cpu_is_ult() might return `true` for ULX SKUs, too, o ULX and Broadwell-ULT SKUs can be `overclocked` with additional cooling, so leave that as devicetree option. For Haswell, the following frequency selections are valid: o ULX: 337.5MHz by default, 450MHz optional o ULT: 450MHz only (maybe 337.5MHz too, documentation varies, it wasn't selectable before either) o others: 540MHz by default, 450MHz optional For Broadwell: o ULX: 450MHz by default, 337.5MHz / 540MHz optional o ULT: 540MHz by default, 337.5MHz / 450MHz / 675MHz optional o others: 667MHz by default, 337.5MHz / 450MHz / 540MHz optional Side effects: A too high setting in the devicetree results in the highest possible frequency now, Haswell non-ULT/ULX defaults to 540MHz instead of 450MHz.

The Broadwell SATA controller supports IOBP registers on ports 0 and 1 but Browell supports up to 4 ports, so we need to support setting IOBP for ports 2 and 3 as well. The magic numbers (IOBP SECRT88 and DTLE) for ports 2 and 3 were only guessed by looking at ports 0 and 1 and extrapolating from there. Port 3 has been tested (DTLE setting on Librem 13) and confirmed to work so we can assume that port 2 and 3 magic numbers are valid, but having someone confirm them (through non-public documents?) would be great.

A re-examination of Intel's reference code reveals that bit 7 should be set for the LP PCH, and bit 27 for non-LP, but not both simultaneously.

2016-12-23spi: Get rid of SPI_ATOMIC_SEQUENCINGFurquan Shaikh
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with the ability to perform tx and rx of flash command and response at the same time. Instead of introducing this notion at SPI flash driver layer, clean up the interface to SPI used by flash. Flash uses a command-response kind of communication. Thus, even though SPI is duplex, flash command needs to be sent out on SPI bus and then flash response should be received on the bus. Some specialized x86 flash controllers are capable of handling command and response in a single transaction. In order to support all the varied cases: 1. Add spi_xfer_vector that takes as input a vector of SPI operations and calls back into SPI controller driver to process these operations. 2. In order to accomodate flash command-response model, use two vectors while calling into spi_xfer_vector -- one with dout set to non-NULL(command) and other with din set to non-NULL(response). 3. For specialized SPI flash controllers combine two successive vectors if the transactions look like a command-response pair. 4. Provide helper functions for common cases like supporting only 2 vectors at a time, supporting n vectors at a time, default vector operation to cycle through all SPI op vectors one by one.
