The ECC check bits of all ECC DIMMS were inadvertently initialized
twice in the same routine, significantly delaying startup. Part
of this was related to an obsolete MCA workaround that has been
fixed through multiple commits, therefore the workaround is no
longer needed.
Only initialize the ECC check bits once.

Certain RDIMMs have inherently large write levelling delays,
in some cases exceeding 1.5 MEMCLK. When these DIMMs are
utilized, the phase recovery system requires special handling
due to the resultant offset exceeding the phase recovery reporting
capabilities.
Fix an old error where delays > 1.5 MEMCLK were not being programmed
(gross delay high bit was not in set range), and restore special
delay handling for delays greater than 1.5 MEMCLK.
Also enhance debugging for x4 DIMMs around the affected code.

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.

Under certain conditions (training abort) BlockRxDqsLock could
remain set in violation of the BKDG. Ensure BlockRxDqsLock is
reset to 0 after a lane training abort.

Rebasing change I3be808db5d15ceec4c36d17582756b01425df09a
did not take into account the default UI setting introduced in
change I6ae88c891e92b21dc0ca3c47b8f3d269f83b3204 , causing DRAM
instability and occassional failure to boot.
Use the correct 1UI value for the modified function semantics.

read_dqs_read_data_timing_registers() and
read_read_dqs_timing_control_registers() served essentially
the same function but had slightly different semantics,
causing confusion and needlessly complex Family15h code.
Consolidate both into read_dqs_read_data_timing_registers()
and adjust surrounding code to match new semantics.

The existing MCT code proceeded to the next DRAM training phase if
the minimum lane quality standard passed for either the read or
write direction. Ensure that both pass for a given set of delay
values before proceeding to the next training phase.

The AMD Family 15h BKDG rev. 3.14 indicates that the maximum read latency
must be calculated prior to DQS position training, however the read
latency calculations use read DQS delay values that have not been
set prior to DQS position training.
Set the read DQS delay values to 1UI (i.e worst case) before calculating
the read latency prior to DQS position training.

A couple of arrays were not properly initialized. This
did not appear to affect operation of the codebase however
it led to some ugly values being displayed when debugging
was turned on.
Also bounds check an array index; as before this did not
appear to affect operation but was a potential point of
failure.
