Now hardcode maximum memory frequency capability to 800MHz, as
all chipsets in x4x family support PC2-6400 according to the datasheet.
CAS latency detection also relies on this, and has been cleaned up.
Ram initialization does not work with FSB 1333MHz / DDR2 800MHz combination,
so disable this combination for now, and reduce to 667MHz instead.
Still don't know why this is the case, but FSB1333/667 works.
These changes should now allow existing configurations to continue working,
while providing support for previously unworking configurations, due to
previous buggy CAS latency detection code.

recovery).
Provide a way to allow mainboards/chipsets to inform recovery module in

recovery reason is set in vbnv after vboot_reference library completes
its verification and clears the reason in vbnv while jumping to

The fixed MTRRs cover the range [0:1MiB). While calculating the
variable MTRR usage the 1MiB boundary is checked such that
an excessive number of MTRRs aren't used because of unnatural
alignment at the low end of the physical address space. Howevever,
those checks weren't inclusive of the 1MiB boundary. As such a
variable MTRR could be used for a range which is actually covered
by the fixed MTRRs when the end address is equal to 1MiB. Likewise,
if the starting address of the range lands on the 1MiB boundary
then more variable MTRRs are calculated in order to meet natural
alignment requirements.

YangtzeSataResetService implements the SataSetMaxGen2 double.
The value should be only set, if the condition is met.
For testing, add
FchParams_env->Sata.SataMode.SataSetMaxGen2 = FALSE;
to your BiosCallOuts.c, which enables GEN3 for the SATA ports.
Patch is tested with bap/e20xx board, Lubuntu 16.04 Kernel 4.4.

The 'dram density' is a misnomer because the memory initialization
code treats that input parameter as a per rank density. Therefore,
update the variables to further clarify how it's actually being
used.

However, the density settings are really on a per rank basis so
