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.

2016-11-14lib/tpm2: do not create all NVRAM spaces with the same set of attributesVadim Bendebury
The TPM spaces created by the RO need to have different attributes depending on the space's use. The firmware rollback counter and MRC hash spaces are created by the RO code and need to be protected at the highest level: it should be impossible to delete or modify the space once the RO exits, and it is how it is done before this patch. The rest of the spaces should be possible to modify or recreate even after the RO exits. Let's use different set of NVRAM space attributes to achieve that, and set the 'pcr0 unchanged' policy only for the firmware counter and MRC cache spaces. The definitions of the attributes can be found in "Trusted Platform Module Library Part 2: Structures", Revision 01.16, section "13.2 TPMA_NV (NV Index Attributes)."

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.

The spi_flash_probe() routine was setting a global varible unconditonally regardless if the probe was for the boot device or even if the boot devcie was flash. Moreover, there's no need to report the SPI information if the boot device isn't even SPI. Lastly, it's possible that the boot device is a SPI flash, but the platform may never probe (selecting SPI_FLASH) for the actual device connected. In that situation don't fill anything in as no correct information is known.

2016-08-19lib/boot_device: add RW boot device constructAaron Durbin
The current boot device usage assumes read-only semantics to the boot device. Any time someone wants to write to the boot device a device-specific API is invoked such as SPI flash. 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.

It's still a high-level option but it correctly depends on BOOT_DEVICE_SPI_FLASH. Additionally that allows the auto-selection of SPI_FLASH by a platform selecting COMMON_CBFS_SPI_WRAPPER which allows for culling of SPI_FLASH selections everywhere.
