Rather than bringing these stubs to the config system, just link them in the bootblock. Note that we cannot fully remove CHIPSET_BOOTBLOCK_INCLUDE at this point, as some intel SOCs use this stub for code flow. objdump -h build/cbfs/fallback/bootblock.debug on a few random boards confirms that the appropriate sections are still included in the final binary.

As the AMD CPUs will generate MCEs on any invalid check bits, this resulted in random lockups during memory training due to the uniniailized check bits. Initialize ECC check bits before enabling ECC hardware.

2015-11-12src/northbridge/amd/amdmct: Add option to override bad SPD checksumTimothy Pearson
Certain DIMMs, for example DIMMs on which the EEPROM has been modified by the end user, may not contain a valid SPD checksum. While this is not a normal condition, it may be useful to allow a checksum override while memory timing parameters are being altered, e.g. in the course of overclocking or underclocking, or when recovering from a bad SPD write. This is an advanced level feature primarily useful for debugging and development.

2015-11-11cpu/amd: Add CC6 supportTimothy Pearson
This patch adds CC6 power save support to the AMD Family 15h support code. As CC6 is a complex power saving state that relies heavily on CPU, northbridge, and southbridge cooperation, this patch alters significant amounts of code throughout the tree simultaneously. Allowing the CPU to enter CC6 allows the second level of turbo boost to be reached, and also provides significant power savings when the system is idle due to the complete core shutdown.

2015-11-11amd/amdmct/mct_ddr3: Use training values from previous boot if possibleTimothy Pearson
DRAM training accounts for most of the romstage startup time, yet if the hardware configuration has not changed from the previous boot the previously discovered training values are still valid. Use them if the DIMM configuration has not changed since the last boot. The SPD values of all installed DIMMs are hashed and stored in the S3 resume data area of the main system Flash device. If a DIMM is changed the hash will almost certainly change as well, forcing retraining on next boot.

2015-11-11amd/amdmct/mct_ddr3: Improve SPD DIMM detect reliabilityTimothy Pearson
Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over I2C on a system with all DIMM slots populated. If even one of those reads has a single flipped bit in it (due to EMI, cross coupling with another trace, or just poor margins on some cheap DIMM) the system will hang and require a hard reset. In practice I've seen failure rates as high as 1 failed boot in 50 due to this issue, granted with cheap DIMMs, but even so retrying the read resolves the corruption issue. I2C is not designed for continuous data transmission with high reliability, and there is no hardware error checking, therefore a single retry when transferring this amount of data makes sense.
