2017-01-12google/chromeos: disable platform hierarchy on resume for TPM2Aaron Durbin
On Chrome OS devices that use TPM2 parts the platform hierarchy is disabled by the boot loader, depthcharge. Since the bootloader isn't involved in resuming a suspended machine there's no equivalent action in coreboot to disable the platform hierarchy. Therefore, to ensure consistent state in resume the platform hierarchy in the TPM2 needs to be disabled as well. For systems that resume using the firmware the platform hierarchy is disabled when utilizing TPM2 devices. BUG=chrome-os-partner:61097 BRANCH=reef TEST=Suspend and resume.

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.

2016-12-08bootstate: add arch specific hook at coreboot exitAaron Durbin
The bootstate machine allows one to schedule work at the boundaries of each state. However, there are no priorities by design. As such if there are things that need to be performed that are interdependent between callbacks there's no way to do that aside from explicitly putting the call in one of the callbacks. This situation arises around BS_OS_RESUME, BS_PAYLOAD_LOAD, and BS_PAYLOAD_BOOT as those are the states where coreboot is about to exit. As such, provide an architecture specific hook at these key places so that one is guaranteed any work done in arch_bootstate_coreboot_exit() is after all callbacks in the state machine.

2016-11-22spi: Get rid of flash_programmer_probe in spi_slave structureFurquan Shaikh
flash_programmer_probe is a property of the spi flash driver and does not belong in the spi_slave structure. Thus, make spi_flash_programmer_probe a callback from the spi_flash_probe function. Logic still remains the same as before (order matters): 1. Try spi_flash_programmer_probe without force option 2. Try generic flash probing 3. Try spi_flash_programmer_probe with force option If none of the above steps work, fail probing. Flash controller is expected to honor force option to decide whether to perform specialized probing or to defer to generic probing.

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.

Therefore, add the ability for a platform to reconfigure the currently running CPU's variable MTRR settings for the duration of coreboot's execution. The function mtrr_use_temp_range() is added which uses the previous MTRR solution as a basis along with a new range and type to use. A new solution is calculated with the updated settings and the original solution is put back prior to exiting coreboot into the OS or payload.

2016-09-19arch/x86,lib: make cbmem console work in postcar stageAaron Durbin
Implement postcar stage cbmem console support. The postcar stage is more like ramstage in that RAM is already up. Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.

2016-08-27cbmem: Always maintain backing store struct in a global on non-x86Julius Werner
The current CBMEM code contains an optimization that maintains the structure with information about the CBMEM backing store in a global variable, so that we don't have to recover it from cbmem_top() again every single time we access CBMEM. However, due to the problems with using globals in x86 romstage, this optimization has only been enabled in ramstage. However, all non-x86 platforms are SRAM-based (at least for now) and can use globals perfectly fine in earlier stages. Therefore, this patch extends the optimization on those platforms to all stages. This also allows us to remove the requirement that cbmem_top() needs to return NULL before its backing store has been initialized from those boards, since the CBMEM code can now keep track of whether it has been initialized by itself.

2016-08-27cbfs: Add "struct" file type and associated helpersJulius Werner
This patch adds functionality to compile a C data structure into a raw binary file, add it to CBFS and allow coreboot to load it at runtime. This is useful in all cases where we need to be able to have several larger data sets available in an image, but will only require a small subset of them at boot (a classic example would be DRAM parameters) or only require it in certain boot modes. This allows us to load less data from flash and increase boot speed compared to solutions that compile all data sets into a stage. Each structure has to be defined in a separate .c file which contains no functions and only a single global variable. The data type must be serialization safe (composed of only fixed-width types, paying attention to padding). It must be added to CBFS in a Makefile with the 'struct' file processor.

2016-08-23memlayout: Ensure TIMESTAMP() region is big enough to avoid BUG()Julius Werner
The timestamp code asserts that the _timestamp region (allocated in memlayout for pre-RAM stages) is large enough for the assumptions it makes. This is good, except that we often initialize timestamps extremely early in the bootblock, even before console output. Debugging a BUG() that hits before console_init() is no fun. This patch adds a link-time assertion for the size of the _timestamp region in memlayout to prevent people from accidentally running into this issue.

Instead, provide a mechanism to retrieve an object that can be used to perform writes to the boot device. On systems where the implementations are symmetric these devices can be treated one-in-the-same. However, for x86 systems with memory mapped SPI the read-only boot device provides different operations.
