There were instances of unneeded arch/hlt.h includes,
various hlt() calls that weren't supposed to exit (but
might have) and various forms of endless loops around
hlt() calls.
All these are sorted out now: unnecessary includes are
dropped, hlt() is uniformly replaced with halt() (except
in assembly, obviously).

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.

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

CPU_MICROCODE_IN_CBFS was designed to mean that loading microcode updates
from a CBFS file is supported, however, the name implies that microcode is

from Google, as well as SAGE. Rename this option to
SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is
"hey, the code we have for this CPU supports loading microcode updates from
CBFS", and prevent further confusion.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

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.

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)

The default TCC activation offset is 0, which means TCC
activation starts at Tj_max. For devices with limited
cooling ability it may be desired to lower TCC activation.
This adds an option that can be declared in the devicetree
to set the TCC activation to a non-zero value.
Enable tcc_offset=15 in devicetree.cb and build/boot

The existing NVS variable for PPCM will be used to
select a dynamic max P-state.
By itself this does not change existing behavior because
the NVS PPCM variable is initialized to zero.
PPCM can be tested by building and booting a modified BIOS
that sets gnvs->ppcm to a value greater than 1 and checking
from the OS that the P-state is limited to that value.

CPUs with configurable TDP will run the TSC at the max non-turbo
ratio for the maximum TDP value, which can cause issues if another
TDP is desired. To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.
This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.
The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.
On some system with 1.8GHz CPU ensure that the kernel
detects the CPU speed as ~1800mhz rather than ~2300mhz:
> dmesg | grep "MHz processor"
[ 0.004000] Detected 1795.801 MHz processor.

Ivybridge B0+ CPUs are capable of supporting multiple TDP levels.
This complicates the default case because now the registers that
were reporting max non-turbo ratio are reporting that value for
the highest possible TDP level.
For now this change just forces everything to use the Nominal TDP
values instead of the higher (or lower) levels.
- When building P-state tables, determine the P[1] (max non turbo)
ratio based on the Nominal ratio if available.
- Set the turbo activation ratio to the Nominal max ratio.
- Mirror the power level settings in new MCHBAR register after
they are written, which happens after BIOS_RESET_CPL is set.
- Set the current ratio to Nominal ratio at boot.
1) Verify that P-state table is generated properly with
P[0]=1801MHz (ratio 0x1C) and P[1]=1800MHz (ratio 0x12)
PSS: 1801MHz power 17000 control 0x1c00 status 0x1c00
PSS: 1800MHz power 17000 control 0x1200 status 0x1200
2) Verify power limits in MCHBAR match PKG_POWER_LIMIT:
> rdmsr 0 0x610
0x800080aa00dc8088
> mmio_read32 0xfed159a4
0x000080aa
> mmio_read32 0xfed159a0
0x00dc8088
3) Verify turbo activation ratio is set to nominal ratio:
> rdmsr 0 0x64c
0x0000000000000012
4) Check that proper ratio was set at boot on one core only:
> grep 'frequency set to' /sys/firmware/log
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800
model_x06ax: frequency set to 1800

There are several reasons for this:
1. It's a core setting, not a platform setting, which is bizarre. But,
we disable vmx via an SMI, and that only happens on core 0.
Hence, the code did not correctly make the same settings on all cores-
one had them disabled, the others were in an unknown state.
When (e.g.) kvm started on a vmx-enabled core, then moved to a
vmx-disabled core, the processor would reset *very* quickly.
Changing this would be messy.
2. On the CPU on link, there is something about trying to set the lock
bit that is getting a GPF.
3. It's the wrong place and time to set it. Once controlled, they can't
be changed in the kernel. The kernel is what should control this
feature, not the BIOS, as we have learned time and time again. If
somebody is in as root and can start a VM, you have a lot more to
worry about than someone starting a guest virtual machine.

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.
