2016-06-04gm45: enable setting all vram sizes from cmosArthur Heymans
Setting the size of the preallocated memory for the igd is done using a cmos parameter, gfx_uma_size. This was limited to a subset of all available sizes, that were already implemented elsewhere in the northbridge code. What this does is change the cmos parameter to 4 bits instead of 3 bits to accomodate all vram sizes. It also adds a sane default of 32mb that already was in place. The northbridge code that reads this cmos parameter is also changed for this new cmos settings. 352M is disabled since it causes issues on systems with 4GB or more ram. TEST: Build, flash target. Clear cmos by corrupting the checksum (nvramtool -c something). Set a desired value in gfx_uma_size using nvramtool. "dmesg | grep stolen" to see what is actually allocated.

2016-04-11and/nb/mct_ddr3: Pack all structures passed to ramstage and set alignmentTimothy Pearson
Two of the MCT data structures passed as substructures to ramstage were not packed, and additionally no alignment was specified. On at least SP5100-based platforms, specifying packed with no alignment caused boot failure dependent on the exact compiled binary layout (LPC hang). Specifying the alignment and packing the remaining structures appears to have resolved the remaining LPC hang issues on the KGPE-D16. Note that packing the remaining structures alone was not sufficient to eliminate the hang, however removing the packed attribute entirely (during debugging) did resolve the hang at the expense of potential problems in ramstage.

2016-04-10nb/intel/sandybridge/raminit: always use mrccachePatrick Rudolph
Always use MRC cache if possible. Added a CRC16 array to make sure the DIMMs haven't been replaced. In case one of the CRC's doesn't match, start normal RAM training. Use new fallback in case of broken mrc cache. Test system: * Gigabyte GA-B75M-D3H * Intel Pentium CPU G2130 Test result: The system boots a lot faster using the MRC cache. On swapping DIMMs the CRC16 doesn't match and normal ram training is started.

2016-04-08nb/amd/mct_ddr3: Cache whether ECC is allowed at the platform levelTimothy Pearson
Certain AMD platforms, such as those using the SP5100 southbridge, contain a very poorly documented bug related to LPC ROM access, which is triggered by repeated (hundreds or more) rapid calls to get_option(). This bug manifests as a complete system deadlock in ramstage device configuration, requiring standby power to be removed from the system to release the deadlock. Cache the platform ECC status to avoid repeated calls to get_option() in the lane count detection logic.

2016-03-31nb/amd_mct_ddr3: Move DRAM MCE sync flood enable to ramstageTimothy Pearson
Enabling sync flood on DRAM MCE directly after ECC clear can lead to a system hang with no way to determine the offending DRAM module. Clear MCEs after ECC setup, but do not enable sync flood until NB setup in ramstage to allow time for any MCEs to accumulate in the status registers. Before enabling sync flood on MCE, determine if any MCEs were logged during ramstage execution and display them on the serial console. Also clear the DRAM ECC sync flood bits during DRAM training and initial ramstage execution.
