2021-04-05soc/amd: Make espi_clear_decodes privateRaul E Rangel
espi_setup already clears most of the controller registers. So this change consolidates the clear logic into one spot. This shouldn't result in a behavior change on Picasso. Picasso already has the eSPI decodes clear on boot, so this change is a nop.

This sets the eSPI registers to the reset values specified in the PPR. On Cezanne, the PSP modifies these registers such that the eSPI peripheral cannot send DEFER packets. This causes random bus errors. These reset values are identical to what is currently used on Zork. I didn't clear out ESPI_DECODE because it's currently being done by cb:51749.

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.

2021-03-27soc/intel: Rename and move MISCCFG_GPIO_PM_CONFIG_BITS definition to soc/gpio.hSubrata Banik
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.

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.

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).

2021-03-16cbfs: 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.

2021-03-15pciexp_device: Rewrite LTR configurationNico Huber
I was bugged by spurious "Failed to enable LTR" messages for years. Looking at the the current algorithm, it is flawed in multiple ways: * It looks like the author didn't know they implemented a recursive algorithm (pciexp_enable_ltr()) inside another recursive algorithm (pciexp_scan_bridge()). Thus, at every tree level, everything is run again for the whole sub- tree. * LTR is enabled no matter if `.set_ltr_max_latencies` is implemented or not. Leaving the endpoints' LTR settings at 0: They are told to always report zero tolerance. In theory, depending on the root-complex implementation, this may result in higher power consumption than without LTR messages. * `.set_ltr_max_latencies` is only considered for the direct parent of a device. Thus, even with it implemented, an endpoint below a (non-root) bridge may suffer from the 0 settings as described above. * Due to the double-recursive nature, LTR is enabled starting with the endpoints, then moving up the tree, while the PCIe spec tells us to do it in the exact opposite order. With the current implementation of pciexp_scan_bridge(), it is hard to hook anything in that runs for each device from top to bottom. So the proposed solution still adds some redundancy: First, for every device that uses pciexp_scan_bus(), we enable LTR if possible (see below). Then, when returning from the bus- scanning recursion, we enable LTR for every device and configure the maximum latencies (if supported). The latter runs again on all bridges, because it's hard to know if pciexp_scan_bus() was used for them. When to enable LTR: * For all devices that implement `.set_ltr_max_latencies`. * For all devices below a bridge that has it enabled already.
