41392df0d1 Merge cpu/intel/acpi.h into cpu/intel/speedstep.h
We had only some MSR definitions in there, which are used in speedstep
related code. I think speedstep.h is the better and less confusing place
for these.

00b579a447 buildsystem: Make CPU microcode updating more configurable
This patch aims to improve the microcode in CBFS handling that was
brought by the last patches from Stefan and the Chromium team.

Choices in Kconfig
  - 1) Generate microcode from tree (default)
  - 2) Include external microcode file
  - 3) Do not put microcode in CBFS

The idea is to give the user full control over including non-free
blobs in the final ROM image.

MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode
is handled by a special class, cpu_microcode, as such:

cpu_microcode-y += microcode_file.c

MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is
needed by intel microcode updating. Once all intel cpus are converted to
cbfs updating, this variable can go away.

These files are then compiled and assembled into a binary CBFS file.
The advantage of doing it this way versus the current method is that
  1) The rule is CPU-agnostic
  2) Gives user more control over if and how to include microcode blobs
  3) The rules for building the microcode binary are kept in
   src/cpu/Makefile.inc, and thus would not clobber the other makefiles,
   which are already overloaded and very difficult to navigate.

537b4e09e6 Add code to read Intel microcode from CBFS
When CONFIG_MICROCODE_IN_CBFS is enabled, find the microcode blob in
CBFS and pass it to intel_update_microcode() instead of using the
compiled in array.

CBFS accesses in pre-RAM and 'normal' environments are provided
through different API.

9ed1456eff Intel CPUs: execute microcode update only once per core
Early HT-enabled CPUs do not serialize microcode updates within a core.
Solve this by running microcode updates on the thread with the smallest
lapic ID of a core only.

Also set MTRRs once per core only.

3f8989ebbc Revamp Intel microcode update code
- add GPLv2 + copyright header after talking to Ron
- "bits" in struct microcode served no real purpose but
  getting its address taken. Hence drop it
- use asm volatile instead of __asm__ volatile
- drop superfluous wrmsr (that seems to be harmless but
  is still wrong) in read_microcode_rev
- use u32 instead of unsigned int where appropriate
- make code usable both in bootblock and in ramstage
- drop ROMCC style print_debug statements
- drop microcode update copy in Sandybridge bootblock

2bdfb48b13 Fixes and Sandybridge support for lapic cpu init
- preprocessor macros should not use defined(CONFIG_*) but
  just CONFIG_*
- drop AMD CPU model 14XXX config variable use. Those do not exist.
- skip some delays on Sandybridge systems
- Count how long we're waiting for each AP to stop
- Skip speedstep specific CPU entries

ea37a21acf Add support for Intel Turbo Boost feature
From wikipedia:
Intel Turbo Boost is a technology implemented by Intel in certain
versions of their Nehalem- and Sandy Bridge-based CPUs, including Core
i5 and Core i7 that enables the processor to run above its base
operating frequency via dynamic control of the CPU's "clock rate".
It is activated when the operating system requests the highest
performance state of the processor.

1ac19e28ee cpu/intel/slot_1: Init L2 cache on SECC(2) CPUs.
Bring from coreboot v1 support for initializing L2 cache on Slot 1
Pentium II/III CPUs, code names Klamath, Deschutes and Katmai.

Build tested on ASUS P2B-LS and P3B-F. Boot tested on P2B-LS with
Pentium III 600MHz, Katmai core.

Also add missing include of model_68x in slot_1, to address a
similar problem fixed for model_6bx by r5945.

Also change Deschutes CPU init sequence to match Katmai.
