Without RELOCATABLE_RAMSTAGE have WB cache large enough
to cover the greatest ramstage needs, as there is no benefit
of trying to accurately match the actual need. Choose
this to be bottom 16MiB.
With RELOCATABLE_RAMSTAGE write-back cache of low ram is
only useful for bottom 1MiB of RAM as a small part of this gets used
during SMP initialisation before proper MTRR setup.

On certain systems and CPUs Core Performance Boost (CPB) may cause
sporadic system lockups. This issue is also somewhat known on the
various proprietary BIOSes, therefore it seems to be a hardware
incompatibility when present.
Allow the user to disable CBP if needed.

Under certain conditions, such as when microcode updates are
being performed, it is important to make sure all APs have
finished updates and are halted before continuing with the
boot process.
Add a new wait_ap_stopped() function to allow for this
functionality to be added to the appropriate mainboard
romstage source files.

The existing code did not allow for the second core of the BSP to
reside on an APIC ID other than 1, leading to a boot hang on Family
15h processors when APIC_ID_OFFSET was set to anything other than 0.
Furthermore, insufficient AP stack space was allocated for AP start.

The existing code generated an incorrect boot APIC ID from node and
core number for single node packages, leading to a boot failure when
the second node was installed.

The existing code did not properly detect various link attributes
on Family 10h/15h processors. With the addition of new HT3- and
IOMMU-specific code, proper detection has become critical to avoid
system deadlocks.

All modern Opteron processors support the HT probe filter,
which helps to increase coherent fabric performance by
reducing the number of HT transactions per cache probe.
AMD recommends that the probe filter be enabled on all
systems with more than two nodes, and it does not hurt
to enable it on systems with 2 nodes.

This patch adds CC6 power save support to the AMD Family 15h
support code. As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.
Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.
