2017-12-07boardid: Add helpers to read sku_id strapping into coreboot tablesJulius Werner
On many recent Chrome OS boards, the desire to unite more configurations under the same image has led to the need of a "SKU ID" that identifies different configurations of the same board (e.g. with certain optional components stuffed or not stuffed, or replaced with a comparable component). This is markedly different from the existing "board ID", because that is reserved to count "revisions" -- changes made to the same configuration over time during the development process. This patch adds support to have a mainboard define this SKU ID and pass it through the coreboot table like we already have for board IDs.

2017-12-07boardid: Switch from Kconfig to weak functionsJulius Werner
This patch switches the board_id and ram_code helper framework to use weak functions rather than Kconfigs to determine whether the board supplies these IDs. This cuts down on the amount of boilerplate Kconfigs many boards have to set and also gives them more flexibility, such as being able to determine at runtime whether a given ID is present.

Merge the different coreboot table strapping ID structures into one because they're really just all the same, and I want to add more. Make the signature of the board_id() function return a uint32_t because that's also what goes in the coreboot table. Add a printk to the generic code handling strapping IDs in ramstage so that not every individual mainboard implementation needs its own print. (In turn, remove one such print from fsp1_1 code because it's in the way of my next patch.)

2017-12-06Kconfig: Remove BOARD_ID_MANUAL optionJulius Werner
The BOARD_ID_MANUAL and BOARD_ID_STRING options were introduced for the Urara board which is now long dead, and have never been used anywhere else. They were trying to do something that we usually handle with a separate SKU ID these days, whereas BOARD_ID is supposed to be reserved for different revisions of the same board/SKU. Get rid of it to make further refactoring of other options easier. Also shove some stuff back into the Urara mainboard that should've never crept into generic headers.

2017-06-29lib/spd_bin: Use proper I2C addressesNico Huber
Use the plain address instead of the weird shifted encoding (e.g. if we'd use `0xa0` as address, it's actually `0x50` encoded into a write command).

2017-06-27lib/coreboot_tables: Zero framebuffer structureDuncan Laurie
Zero the framebuffer structure so if it is not filled in (either if no display is present or if there is an error) then it does not provide garbage data to the payload. This was noticed when booting a board without a display attached as the payload wrote to the framebuffer at a random address. With this change the payload can properly handle the case where a display is not attached and not corrupt memory.

2017-06-21cr50: process uninitialized values gracefullyVadim Bendebury
The vboot code tries reading rollback protection indices from the TPM, and if the attempt to read returns TPM_E_BADINDEX, it decides that the TPM has not yet been initialized for the Chromebook use, and needs to be taken through the factory initialization sequence. TPM_E_BADINDEX is an internal representation of the TPM error 0x28b, generated on attempts to read a non existing NVMEM space. If the space exists, but has never been written the TPM returns error 0x14a. This condition (the space exists but not written) could happen if the previous factory initialization attempt was interrupted right after the space was created. Let's map this error to the same internal representation (TPM_E_BADINDEX) so that the Chrome OS device could recover when this condition occurs. BRANCH=reef, gru BUG=b:37443842 TEST=verified that the Pyro device stuck in TPM error state recovered when this patch was applied.

Initial support for undefined behavior sanitizer in ramstage. Enabling this will add -fsanitize=undefined to the compiler command line and link with ubsan.c in ramstage. Code with UB triggers a report with error, file, and line number, then aborts.

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.
