2021-05-14cbfs: Increase mcache size defaultsJulius Werner
The CBFS mcache size default was eyeballed to what should be "hopefully enough" for most users, but some recent Chrome OS devices have already hit the limit. Since most current (and probably all future) x86 chipsets likely have the CAR space to spare, let's just double the size default for all supporting chipsets right now so that we hopefully won't run into these issues again any time soon. The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under the assumption that Chrome OS images have historically always had a lot more files in their RO CBFS than the RW (because l10n assets were only in RO). Unfortunately, this has recently changed with the introduction of updateable assets. While hopefully not that many boards will need these, the whole idea is that you won't know whether you need them yet at the time the RO image is frozen, and mcache layout parameters cannot be changed in an RW update. So better to use the normal 50/50 split on Chrome OS devices going forward so we are prepared for the eventuality of needing RW assets again. The RW percentage should really also be menuconfig-controllable, because this is something the user may want to change on the fly depending on their payload requirements. Move the option to the vboot Kconfigs because it also kinda belongs there anyway and this makes it fit in better in menuconfig. (I haven't made the mcache size menuconfig-controllable because if anyone needs to increase this, they can just override the default in the chipset Kconfig for everyone using that chipset, under the assumption that all boards of that chipset have the same amount of available CAR space and there's no reason not to use up the available space. This seems more in line with how this would work on non-x86 platforms that define this directly in their memlayout.ld.) Also add explicit warnings to both options that they mustn't be changed in an RW update to an older RO image.

For AMD's family 17h, verstage can run as a userspace app in the PSP before the X86 is released. The flags for this have been made generic to support any other future systems that might run verstage before the main processor starts. Although an attempt has been made to make things somewhat generic, since this is the first and currently only chip to support verstage before bootblock, there are a number of options which might ultimately be needed which have currently been left out for simplicity. Examples of this are: - PCI is not currently supported - this is currently just a given instead of making a separate Kconfig option for it. - The PSP uses an ARM v7 processor, so that's the only processor that is getting updated for the verstage-before-bootblock option.

2020-03-31security/vboot: Decouple measured boot from verified bootBill XIE
Currently, those who want to use measured boot implemented within vboot should enable verified boot first, along with sections such as GBB and RW slots defined with manually written fmd files, even if they do not actually want to verify anything. As discussed in CB:34977, measured boot should be decoupled from verified boot and make them two fully independent options. Crypto routines necessary for measurement could be reused, and TPM and CRTM init should be done somewhere other than vboot_logic_executed() if verified boot is not enabled. In this revision, only TCPA log is initialized during bootblock. Before TPM gets set up, digests are not measured into tpm immediately, but cached in TCPA log, and measured into determined PCRs right after TPM is up. This change allows those who do not want to use the verified boot scheme implemented by vboot as well as its requirement of a more complex partition scheme designed for chromeos to make use of the measured boot functionality implemented within vboot library to measure the boot process. TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

Further more, most Chromebooks are using HWID v3+ today while the test-only HWID is usually v2. Non-Chrome OS developers may also prefer their own format. To simplify development process, the GBB_CONFIG now defaults to empty string, and will be replaced by a board-specific test-only v2 HWID automatically.

2019-07-03vboot: Use CONFIG_VBOOT_MIGRATE_WORKING_DATA on all platformsJulius Werner
When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on some Arm platforms the original working data buffer was in SRAM, which stays accessbile for the whole runtime of the system. There is no reason to migrate it into CBMEM on those platforms because ramstage and the payload could continue to access it in SRAM. Now that we've had a couple of months of experience with this option, we found that most of our Arm platforms have some issue that requires migrating anyway, because BL31 often claims SRAM for itself and makes it inaccessible to the payload. On the remaining platforms, accessing SRAM from the payload is possible but still an issue, because libpayload doesn't have enough memory layout information to set up proper page tables for it, so we're accessing it uncached and at risk of alignment errors. Rather than having to figure out how to map the right SRAM range for every platform in the payload, let's just get rid of the option. memcpy()ing 12KB isn't worth this much hassle.

2019-04-01vboot: Select CONFIG_VBOOT_OPROM_MATTERS in more casesJulius Werner
This patch enables CONFIG_VBOOT_OPROM_MATTERS in a few more cases where I think(?) it should be. Haswell, Broadwell and Baytrail Chromebooks have this enabled in their old depthcharge firmware branches -- we presumably just forgot to move it over when vboot2 migrated the option to coreboot. Braswell didn't, but it seems like this requirement was added when it was migrated to FSP 1.1...? (Not very sure about that one, but it does call load_vbt() right now which executes things based on display_init_required().) Additionally, it seems to make sense to enable it whenever the user explicitly selects VGA_ROM_RUN in menuconfig (like one of the Intel defconfigs does). Once we have all this, one could take a step back and ask whether this option still makes sense at all anymore. It's enabled for almost all devices (that work with vboot at all), it will presumably be enabled for all future devices, and it seems that most devices that don't enable it use libgfxinit, which as far as I can tell isn't gated on display_init_required() but probably should be. Realistically, whatever kind of display init a board needs to do (native or option ROM), it's probably expensive enough that it's worth skipping on a normal mode vboot boot, and we'd want to have this enabled by default on everything except boards that actually don't have a display. So maybe we should flip it around to CONFIG_VBOOT_OPROM_DOESNT_MATTER, but doing that would probably lead to nobody ever selecting it at all. Not sure what the best solution there is yet, but I think this patch at least moves things in the more correct direction.

The following three modes are available: -RO only -RO + RW_A -RO + RW_A + RW_B The mode "RO only" is the lowest mode with no safety during update. You can select either RW_A or RW_AB via Kconfig which will add the selected parttions to the final image.

Move soft_reset() to `southbridge/amd/common/` it's only used for amdfam10 now. Drop hard_reset() for good.

2018-10-22reset: Provide new single-function reset APINico Huber
board_reset() replaces the existing common reset API. There is no common distinction between reset types across platforms, hence, common code could never decide which one to call. Currently only hard_reset() is used by common code. We replace these calls and provide a fall-back to the current hard_reset() implemen- tation. The fall-back will be removed along with hard_reset() after the transition of all boards.

2018-05-03security/vboot: make vboot starts in bootblock depend on c envAaron Durbin
coreboot on skylake originally did ship with romcc bootblock and verstage running after it. However, that configuration makes boot flows very complicated. No platform in the current code base uses this combination. Make VBOOT_STARTS_IN_BOOTBLOCK depend on C_ENVIRONMENT_BOOTBLOCK.

2018-01-17security/vboot: Add two weak methods for vboot2Philipp Deppenwiese
In order to make VBOOT2 independent from the CHROMEOS kconfig option a weak method for get_write_protect_state and get_recovery_mode_switch() is required. Introduce a kconfig option for controlling this behaviour. This is a temporary fix and will be removed afterwards.
