2016-08-31driver/intel/fsp2.0: Add External stage cache region helperRizwan Qureshi
If ramstage caching outside CBMEM is enabled i.e CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM, then a helper function to determine the caching region in SMM should be implemented. Add the same to FSP2.0 driver. FSP1.1 driver had the same implementation hence copied stage_cache.c. The SoC code should implement the smm_subregion to provide the base and size of the caching region within SMM. The fsp/memmap.h provides the prototype and we will reuse the same from FPS 1.1.

2016-08-25vboot: consolidate google_chromeec_early_init() callsAaron Durbin
On x86 platforms, google_chromeec_early_init() is used to put the EC into RO mode when there's a recovery request. This is to avoid training memory multiple times when the recovery request is through an EC host event while the EC is running RW code. Under that condition the EC will be reset (along with the rest of the system) when the kernel verification happens. This leads to an execessively long recovery path because of the double reboot performing full memory training each time. By putting this logic into the verstage program this reduces the bootblock size on the skylake boards. Additionally, this provides the the correct logic for all future boards since it's not tied to FSP nor the mainboard itself. Lastly, this double memory training protection works only for platforms which verify starting from bootblock. The platforms which don't start verifying until after romstage need to have their own calls (such as haswell and baytrail).

2016-08-24drivers/spi: remove unconditional RW boot device initializationAaron Durbin
The SPI drivers for the various chipsets are not consistent in their handling of when they are accessible. Coupled with the unknown ordering of boot_device_init() being called this can lead to unexpected behavior (probing failures or hangs). Instead move the act of initializing the SPI flash boot device to when the various infrastructure requires its usage when it calls boot_device_rw(). Those platforms utilizing the RW boot device would need to ensure their SPI drivers are functional and ready when the call happens. This further removes any other systems failing to boot as reported in https://ticket.coreboot.org/issues/67.

2016-08-23drivers/spi: be sure to call spi_init() before spi_flash_probe()Aaron Durbin
It's necessary to call spi_init() prior to calling spi_flash_probe() such that the SPI drivers can do any work required prior to performing SPI transactions. It could be argued that the drivers should handle such situations, however the SPI API implementations seem to assume the callers ensured spi_init() was called before any SPI transactions.

2016-08-19drivers/spi: provide optional implementation of boot_device_rw()Aaron Durbin
On many x86 platforms the boot device is SPI which is memory mapped. However, in order to write to the boot device one needs to use the SPI api. Therefore, provide a common implementation of boot_device_rw() which has no mmap() functionality. It only reads, writes, and erases. This will be used in the existing infrastructure but in a SPI agnostic way. Two options are added: 1. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP 2. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY The former is auto-selected when COMMON_CBFS_SPI_WRAPPER is not selected. The latter can be used to include the implementation in the early stages such as bootblock, verstage, and romstage.

There was a check against the next event offset against the shrink size in elog_shrink(). However, all calls to elog_shrink() were conditionalized on the next event offset exceeding the full threshold. The shrink size is set to the minimum of the full threshold and a percentage of the elog region size. Therefore, it's impossible for the next event offset to be less than the shrink size because full threshold is always greater than or equal to the shrink size.

2016-08-08drivers/elog: use event region size when adding a clear eventAaron Durbin
For the elog shrink case we log the number of bytes shrunk from the event log. However, when clearing the log the size recorded was the entire region size including the header as well as the event region space. To be more consistent mark the clearing event with the number of bytes actually cleared out (excluding the header size).

2016-08-05drivers/spi: Add support for Micron N25Q128AWerner Zeh
Although we have already support for the flash chip N25Q128 there is a similar type available which has the same geometry and opcodes but unfortunately a slightly different device type ID. While the already supported N25Q128 has the ID 0xbb18 this one has the ID 0xba18. To make both types available in the flash support table, use N25Q128A as the flash name. This name can be found in the datasheet which can be found here: https://www.micron.com/~/media/documents/products/data-sheet/nor-flash/serial-nor/n25q/n25q_128mb_3v_65nm.pdf TEST=Booted and verified that MRC cache could be written Change-Id: I02a47692efb23a9a06a289c367488abd256b8e0c Signed-off-by: Werner Zeh <werner.zeh@siemens.com> Reviewed-on: https://review.coreboot.org/16061 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Patrick Georgi <pgeorgi@google.com>

The TPM version string has become much longer recently, and the TPM_FW_VER register available on VID 1ae0 devices supports reading in arbitrary size quantities.
