The CPU can arbitrarily reorder calls to rdtsc, significantly
reducing the precision of timing using the CPUs time stamp counter.
Unfortunately the method of synchronizing rdtsc is different
on AMD and Intel CPUs. There is a generic method, using the cpuid
instruction, but that uses up a lot of registers, and is very slow.
Hence, use the correct lfence/mfence instructions (for CPUs that
we know support it)

CACHE_ROM_SIZE default is ROM_SIZE, the Flash device size set
in menuconfig. This fixes a case where 8 MB SPI flash MTRR setup
would not cover the bottom 4 MB when ramstage is decompressed.
Verify CACHE_ROM_SIZE is power of two.
One may set CACHE_ROM_SIZE==0 to disable this cache.

A diff from model_6fx to model_106cx suggests there is little

In its current status however, sockets supporting model_6fx use

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.

The current code uses static values for the physical address size
supported by a CPU. This isn't always the right value: I.e. on
model_6[ef]x Core (2) Duo CPUs physical address size is 36, while
Xeons from the same family have 38 bits, which results in invalid
MTRR setup. Fix this by getting the right number from CPUID.
