2015-03-23vboot2: read secdata and nvdataDaisuke Nojiri
This code ports antirollback module and tpm library from platform/vboot_reference. names are modified to conform to coreboot's style. The rollback_index module is split in a bottom half and top half. The top half contains generic code which hides the underlying storage implementation. The bottom half implements the storage abstraction. With this change, the bottom half is moved to coreboot, while the top half stays in vboot_reference. TEST=Built with USE=+/-vboot2 for Blaze. Built Samus, Link.

2015-03-18bootstate: use structure pointers for scheduling callbacksAaron Durbin
The GCC 4.9.2 update showed that the boot_state_init_entry structures were being padded and assumed to be aligned in to an increased size. The bootstate scheduler for static entries, boot_state_schedule_static_entries(), was then calculating the wrong values within the array. To fix this just use a pointer to the boot_state_init_entry structure that needs to be scheduled. In addition to the previous issue noted above, the .bs_init section was sitting in the read only portion of the image while the fields within it need to be writable. Also, the boot_state_schedule_static_entries() was using symbol comparison to terminate a loop which in C can lead the compiler to always evaluate the loop at least once since the language spec indicates no 2 symbols can be the same value.

The FSP uses a lot of UEFI HOB (Hand Off Block) functions for reporting and passing information to coreboot. These seem to me like they should be in their own file, so I'm splitting them out of fsp_util.c. I'll be adding a couple more functions in the next patch.

This patch has a rather twisted history. It was originally split off from a chromium patch, which moved ALTCENTURY to Kconfig.

2014-12-30Provide a common CBFS wrapper for SPI storageVadim Bendebury
Coreboot has all necessary infrastructure to use the proper SPI flash interface in bootblock for CBFS. This patch creates a common CBFS wrapper which can be enabled on different platforms as required. COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the common CBFS interface and prevents default inclusion of all SPI chip drivers, only explicitly configured ones will be included when the new feature is enabled. Since the wrapper uses the same driver at all stages, enabling the new feature will also make it necessary to include the SPI chip drivers in bootblock and romstage images. init_default_cbfs_media() can now be common for different platforms, and as such is defined in the library. BUG=none TEST=manual . with this change and the rest of the patches coreboot on AP148 comes up all the way to attempting to boot the payload (reading earlier stages from the SPI flash along the way).

2014-12-17spi_flash: Move (de-)assertion of /CS to single locationDavid Hendricks
This consolidates all calls to spi_claim_bus() and spi_release_bus() to a single location where spi_xfer() is called. This avoids confusing (and potentially redundant) calls that were being done throughout the generic spi_flash.c functions and chip-specific functions. I don't think the current approach could even work since many chip drivers assert /CS once and then issue multiple commands such as page program followed by reading the status register. I suspect the reason we didn't notice it on x86 is because the ICH/PCH handled each individual command correctly (spi_claim_bus() and spi_release_bus() are noops) in spite of the broken code.

2014-12-17spi_flash: Differentiate between atomic/manual sequencingDavid Hendricks
This adds a wrapper function and a Kconfig variable to differentiate between SPI controllers which use atomic cycle sequencing versus those where the transaction sequence is controlled manually. Currently this boils down to x86 vs. non-x86. Yes, it's hideous. The current API only worked because, for better or worse, x86 platforms have been homogeneous in this regard since they started using SPI as an alternative to FWH for boot flash. Now that we have non-x86 platforms which use general purpose SPI controllers, we should overhaul the entire SPI infrastructure to be more adaptable.
