Some CPUs, (Intel core2 and pineview) have slightly different SMRR
MTRR mechanism. The MSR_SMRR_PHYSBASE/MASK MSRs are at a different
location, have slightly different semantics and need SMRR enable in a
locked down IA32_FEATURE_CONTROL MSR.
This change takes away the possibility to (not) lock
IA32_FEATURE_CONTROL on these CPUs, as this is needed for SMRR MSR to
work. Since sockets cover multiple CPUs of which only some support
SMRR, the Kconfig option CONFIG_SET_IA32_FC_LOCK_BIT is kept in place,
even though it gets meaningless on those CPUs. Locking that bit was
the default anyway.
With this patch Intel Netburst CPUs also configure
IA32_FEATURE_CONTROL. According to Intel 64 and IA-32 Architectures
Software Developer's Manual those CPUs support that MSR so issues are
not to be expected.

Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

of ramstage copy_and_run are only partly set cacheable.
It appears variable MTRR setting for XIP cache is left enabled on
model_106cx code, where it should have extended to cover all of Flash.

A diff from model_6fx to model_106cx suggests there is little
CORE2 specific code that was once considered useful to have.
In its current status however, sockets supporting model_6fx use
model_6ex CAR init, so that specific code is actually
never used.

Default CPU_ADDR_BITS is 36.
For Atom (model_106cx) use 32. This model is known to
fail execution-in-place (XIP) with the default 36.
Pentium M should use 32, but doesn't even with this patch.
Some Xeon and CORE(2) models should use 38 or 40.

The current code for initializing AP cpus has several shortcomings:
- it assumes APIC IDs are sequential
- it uses only the BSP for determining the AP count, which is bad if
there's more than one physical CPU, and CPUs are of different type
Note that the new code call cpu->ops->init() in parallel, and therefore
some CPU code needs to be changed to address that. One example are old
Intel HT enabled CPUs which can't do microcode update in parallel.
