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.

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.

The only reliable way I have found to detect when this

if DQS position training fails, adding the delay and
retraining.
This is probably related in some form or another to
