2016-12-15soc/intel/common: provide option to invalide MRC cache on recoveryAaron Durbin
Allow a board/platform to invalidate the normal MRC cache when hardware retraining is requested in recovery mode. A small 4 byte payload is used to update the latest data written. It will of course fail on MRC cache retreival on next usage.

Piggy-back on existing MRC cache infrastructure to store variable MRC data. Only one set of data can be valid at given point of time. Currently this magically happens because region alignment is forced to 0x1000 and region itself is of the same size. This needs to be somehow programmatically enforced.

1. Re-factor MRC cache driver to properly select RW_MRC_CACHE or RECOVERY_MRC_CACHE based on the boot mode. - If normal mode boot, use RW_MRC_CACHE, if available. - If recovery mode boot: - Retrain memory if RECOVERY_MRC_CACHE not present, or recovery is requested explicity with retrain memory request. - Use RECOVERY_MRC_CACHE otherwise. 2. Protect RW and RECOVERY mrc caches in recovery and non-recovery boot modes. Check if both are present under one unified region and protect that region as a whole. Else try protecting individual regions. 3. Update training data in appropriate cache: - Use RW_MRC_CACHE if normal mode. - Use RECOVERY_MRC_CACHE if present in recovery mode.

2016-06-09soc/intel/common: Add LPSS I2C driverDuncan Laurie
Add a generic LPSS I2C driver for Intel SOCs that use the Synopsys DesignWare I2C block and have a similar configuration of that block. This driver is ported from the Chromium depthcharge project where it was ported from U-Boot originally, though it looks very different now. From depthcharge it has been modified to fit into the coreboot I2C driver model with platform_i2c_transfer() and use coreboot semantics throughout including the stopwatch API for timeouts. In order for this shared driver to work the SOC must: 1) Define CONFIG_SOC_INTEL_COMMON_LPSS_I2C_CLOCK_MHZ to set the clock speed that the I2C controller core is running at. 2) Define the lpss_i2c_base_address() function to return the base address for the specified bus. This could be either done by looking up the PCI device or a static table if the controllers are not PCI devices and just have a static base address. The driver is usable in verstage/romstage/ramstage, though it does require early initialization of the controller to set a temporary base address if it is used outside of ramstage. This has been tested on Broadwell and Skylake SOCs in both pre-RAM and ramstage environments by reading and writing both single bytes across multiple segments as well as large blocks of data at once and with different configured bus speeds. While it does need specific configuration for each SOC this driver should be able to work on all Intel SOCs currently in src/soc/intel.

This patch implements Memory Margin Analysis feature in coreboot. Few things to note (1) the feature is enabled by setting CONFIG_MMA=y in the config file (2) coreboot reads mma_test_metadata.bin from cbfs during romstage and gets the name of MMA test name and test config name. Then coreboot finds these files in CBFS. If found, coreboot passes location and size of these files to FSP via UPD params. Sets MrcFastBoot to 0 so that MRC happens and then MMA test would be executed during memory init. (3) FSP passes MMA results data in HOB and coreboot saves it in cbmem (4) when system boots to OS after test is executed cbmem tool is used to grab the MMA results data.

2015-04-18soc/intel/common: Add function to protect MRC cacheDuncan Laurie
Add support for applying write protection to the MRC cache region in SPI flash. This is only enabled if there is write protect GPIO that is set, and the flash status register reports that the flash chip is currently write protected. Then it will call out to a SOC specific function that will enable write protection on the RW_MRC_CACHE region of flash. The implementation is not quite as clean as I would like because there is not a common flash protect interface across SOCs so instead it relies on a new Kconfig variable to be set that will indicate a SOC implements the function to protect a region of SPI flash.
