2021-04-08soc/intel: Hook up `SOC_INTEL_DISABLE_IGD` to `InternalGfx` UPDAngel Pons
Commit 0591348833f730a42e74039d8e2d957ec94a39d5 introduced this Kconfig option inside soc/intel/common scope. However, it was only hooked up in commit d74cd60b8159c3928dba318e6387f200ff3bb0e7 for Alder Lake, and in commit 99157c1f4a80556462ca22a4ade87b2c8d09e674 for Tiger Lake. Hook up the `SOC_INTEL_DISABLE_IGD` Kconfig option to all other platforms which have the `InternalGfx` UPD.

2021-04-07vc/amd/fsp/cezanne: update UPD headersMatt Papageorge
The UPD header files get generated as part of the FSP build process. For the initial Cezanne development we took the Picasso UPD data structures as a starting point. This patch replaces it with the first version of the Cezanne-specific UPD data structures that is present in version 12 of the internal work-in-progress FSP binary drops. The serial_port_stride UPD-M field is removed, since the information is already given by serial_port_use_mmio. The stride is 4 bytes for the MMIO UART case and 1 byte for the legacy I/O case.

2021-04-06intel/tigerlake: Add Acoustic featuresShaunak Saha
On VCCin there was an oscillation which occurred just as the kernel started (kernel starting... message). On some devices, this behavior seems even worse. In previous platforms VCCin toggled for a few ms and then was stable. For volteer, this happens at the same point in time for around 40ms. However, it starts oscillating again later in the boot sequence. Once at the root shell, it seems to oscillate indefinitely at around 100-200Hz (very variable though). To fix this we need to control the deep C-state voltage slew rate.We have options for controlling the deep C-state voltage slew rate through FSP UPDs. This patch expose the following FSP UPD interface into coreboot: - AcousticNoiseMitigation - FastPkgCRampDisable - SlowSlewRate We are setting SlowSlewRate for all volteer boards to 2 which is Fast/8. TGL has a single VR domain(Vccin). Hence, the chip config is updated to allow mainboards to set a single value instead of an array and FSP UPDs are accordingly set. BUG=b:153015585 BRANCH=firmware-volteer-13672.B TEST= Measure the change in noise level by changing the UPD values.

2021-04-06soc/intel/common: Prevent SMI storm when setting SPI WPD bitAngel Pons
From Skylake/Sunrise Point onwards, there are two BIOS_CNTL registers: one on the LPC/eSPI PCI device, and another on the SPI PCI device. When the WPD bit changes from 0 to 1 and the LE bit is set, the PCH raises a TCO SMI with the BIOSWR_STS bit set. However, the BIOSWR_STS bit is not set when the TCO SMI comes from the SPI or eSPI controller instead, but a status bit in the BIOS_CNTL register gets set. If the SMI cause is not handled, another SMI will happen immediately after returning from the SMI handler, which results in a deadlock. Prevent deadlocks by clearing the SPI synchronous SMI status bit in the SMI handler. When SPI raises a synchronous SMI, the TCO_STS bit in the SMI_STS register is continously set until the SPI synchronous SMI status bit is cleared. To not risk missing any other TCO SMIs, do not clear the TCO_STS bit again in the same SMI handler invocation. If the TCO_STS bit remains set when returning from SMM, another SMI immediately happens and clears the TCO_STS bit, handling any pending events. SPI can also generate asynchronous SMIs when the WPD bit is cleared and one attempts to write to flash using SPI hardware sequencing. This patch does not account for SPI asynchronous SMIs, because they are disabled by default and cannot be enabled once the BIOS Interface Lock-Down bit in the BIOS_CNTL register has been set, which coreboot already does. These asynchronous SMIs set the SPI_STS bit of the SMI_STS register. Clearing the SPI asynchronous SMI source should be done inside the SPI_STS SMI handler, which is currently not implemented. All of this goes out of the scope of this patch, and is currently not necessary anyway. This patch does not handle eSPI because I cannot test it, and knowing if a board uses LPC or eSPI from common code is currently not possible, and this is beyond the scope of what this commit tries to achieve (fix SPI). Tested on HP 280 G2, no longer deadlocks when SMM BIOS write protection is on. Write protection will be enforced in a follow-up.

2021-03-30mb/ti/beaglebone: Load romstage/ramstage from SDSam Lewis
Adds a "sd_media" boot_device to allow booting from the SD card. This assumes that the generated "MLO" file is placed at a 128KB offset from the start of the SD card, to allow for the MBR etc. to be at the start of the SD card. Placing the MLO file here allows the AM335x boot ROM to load and execute the bootblock stage as well, as 128KB is one of the offsets the boot ROM checks when looking for the next stage to execute. As part of this, a FMD for the Beaglebone has also been defined. It's sized at 32M somewhat arbitrarily, as SD cards could allow for much bigger payloads. TEST: Beaglebone boots from bootblock into romstage. Romstage to ramstage still doesn't work as it needs RAM initialization first.

Lists of changes: 1. Rename MISCCFG_ENABLE_GPIO_PM_CONFIG -> MISCCFG_GPIO_PM_CONFIG_BITS 2. Move MISCCFG_GPIO_PM_CONFIG_BITS definition from intelblock/gpio.h to soc/gpio.h. Refer to detailed description below to understand the motivation behind this change. An advanced GPIO PM capabilities has been introduced since CNP PCH, refer to 'include/intelblock/gpio.h' for detailed GPIO PM bit definitions. Now with TGP PCH, additional bits are defined in the MISCCFG register for GPIO PM control. This results in different SoCs supporting different number of bits. The bits defined in earlier platforms (CNL, CML, ICL) are present on TGL, JSL and ADL too. Hence, refactor the common GPIO code to keep the bit definitions in intelblock/gpio.h, but the definition of MISCCFG_GPIO_PM_CONFIG_BITS is moved to soc/gpio.h so that each SoC can provide this as per hardware support. TEST=On ADL, TGL and JSL platform.

2021-03-24soc/mediatek: Use MRC cache API for asuradaYu-Ping Wu
Use the MRC cache API for asurada, and sync dramc_param.h with dram blob (CL:*3674585). With this change, the checksum, originally stored in flash, is replaced with a hash in TPM. In addition, in recovery boot, full calibration will always ne performed, and the cached calibration data will be cleared from flash. This change increases ROMSTAGE size from 236K to 264K. Most of the increase is caused by TPM-related functions. Add new API mtk_dram_init() to emi.h, so that 'dramc_parameter' can be moved to soc folder. With this CL, there is no significant change in boot time. Normal AP reboot time (fast calibration) is consistently 0.98s as before, so this change should not affect the result of platform_BootPerf.

2021-03-17cbfs: Move stage header into a CBFS attributeJulius Werner
The CBFS stage header is part of the file data (not the header) from CBFS's point of view, which is problematic for verification: in pre-RAM environments, there's usually not enough scratch space in CBFS_CACHE to load the full stage into memory, so it must be directly loaded into its final destination. However, that destination is decided from reading the stage header. There's no way we can verify the stage header without loading the whole file and we can't load the file without trusting the information in the stage header. To solve this problem, this patch changes the CBFS stage format to move the stage header out of the file contents and into a separate CBFS attribute. Attributes are part of the metadata, so they have already been verified before the file is loaded. Since CBFS stages are generally only meant to be used by coreboot itself and the coreboot build system builds cbfstool and all stages together in one go, maintaining backwards-compatibility should not be necessary. An older version of coreboot will build the old version of cbfstool and a newer version of coreboot will build the new version of cbfstool before using it to add stages to the final image, thus cbfstool and coreboot's stage loader should stay in sync. This only causes problems when someone stashes away a copy of cbfstool somewhere and later uses it to try to extract stages from a coreboot image built from a different revision... a debugging use-case that is hopefully rare enough that affected users can manually deal with finding a matching version of cbfstool. The SELF (payload) format, on the other hand, is designed to be used for binaries outside of coreboot that may use independent build systems and are more likely to be added with a potentially stale copy of cbfstool, so it would be more problematic to make a similar change for SELFs. It is not necessary for verification either, since they're usually only used in post-RAM environments and selfload() already maps SELFs to CBFS_CACHE before loading them to their final destination anyway (so they can be hashed at that time).

2021-03-17program_loading: Replace prog_rdev() with raw start pointer and sizeJulius Werner
Since prog_locate() was eliminated, prog_rdev() only ever represents the loaded program in memory now. Using the rdev API for this is unnecessary if we know that the "device" is always just memory. This patch changes it to be represented by a simple pointer and size. Since some code still really wants this to be an rdev, introduce a prog_chain_rdev() helper to translate back to that if necessary.

2021-03-16cbfs: Remove prog_locate() for stages and rmodulesJulius Werner
This patch removes the prog_locate() step for stages and rmodules. Instead, the stage and rmodule loading functions will now perform the locate step directly together with the actual loading. The long-term goal of this is to eliminate prog_locate() (and the rdev member in struct prog that it fills) completely in order to make CBFS verification code safer and its security guarantees easier to follow. prog_locate() is the main remaining use case where a raw rdev of CBFS file data "leaks" out of cbfs.c into other code, and that other code needs to manually make sure that the contents of the rdev get verified during loading. By eliminating this step and moving all code that directly deals with file data into cbfs.c, we can concentrate the code that needs to worry about file data hashing (and needs access to cbfs_private.h APIs) into one file, making it easier to keep track of and reason about. This patch is the first step of this move, later patches will do the same for SELFs and other program types.
