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.

2016-03-31nb/amd/mct_ddr3: Clear early MCEs and report DRAM MCEsTimothy Pearson
During power on from cold (S5) state, numerous MCEs are generated before DRAM training starts, e.g. during HT link training. Clear these MCEs before DRAM training start, and report any MCEs generated during DRAM training.
