aaa4a0d39e cpu/intel/common/fsb.c: Add Broadwell CPUID models
Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for
both the traditional and ULT variants of Broadwell, because the CPU
driver for Haswell already contains CPUIDs for both Broadwell types.

Without this patch, Broadwell CPUs would hang when trying to print the
first console log message, but only if flashconsole was not enabled.

This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell
CPUIDs and microcode) and went unnoticed until now because the tests
were done with flashconsole enabled, which somehow boots properly even
though the console time tracking would not work (depends on TSC).

Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.

b01ac7e264 cpu/intel/common: Fill cpu voltage in SMBIOS tables
Introduce a weak function to let the platform code provide the processor

Implement the function on Intel platforms using the MSR_PERF_STATUS msr.
On other platforms the processor voltage still reads as unknown.

Tested on Intel CFL. The CPU voltage is correctly advertised.

cbd4ee73d7 cpu/intel/common: correct MSR for the Nominal Performance in CPPC
The "Nominal Performance" is not the same as the "Guaranteed
Performance", but is defined as the performance a processor can deliver
continously under ideal environmental conditions.

According to edk2, this is the "Maximum Non-Turbo Ratio", which needs to
be read from MSR_PLATFORM_INFO instead of IA32_HWP_CAPABILITIES.

Correct the entry in the CPPC package.

76cedd2c29 acpi: Move ACPI table support out of arch/x86 (3/5)
This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.

In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

c9b13594eb src/: Remove g_ prefixes and _g suffixes from variables
These were often used to distinguish CAR_GLOBAL variables that weren't
directly usable. Since we're getting rid of this special case, also get
rid of the marker.

This change was created using coccinelle and the following script:
	@match@
	type T;
	identifier old =~ "^(g_.*|.*_g)$";
	@@
	old

	@script:python global_marker@
	old << match.old;
	new;
	@@
	new = old
	if old[0:2] == "g_":
	  new = new[2:]

	if new[-2:] == "_g":
	  new = new[:-2]

	coccinelle.new = new

	@@
	identifier match.old, global_marker.new;
	@@
	- old
	+ new

	@@
	type T;
	identifier match.old, global_marker.new;
	@@
	- T old;
	+ T new;

	@@
	type T;
	identifier match.old, global_marker.new;
	@@
	- T old
	+ T new
	 = ...;

There were some manual fixups: Some code still uses the global/local
variable naming scheme, so keep g_* there, and some variable names
weren't completely rewritten.

Will be used in MP init to only write "Core" MSRs from one thread
on HyperThreading enabled platforms, to prevent race conditions and
resulting #GP if MSRs are written twice or are already locked.

fe26be1181 cpu/intel/common: Fix invalid MSR access
Fix regression from commit ecea916

   cpu/intel/common: Extend FSB detection to cover TSC

MSR_EBC_FREQUENCY_ID (0x2c) was not defined for affected
CPU models and rdmsr() caused reset loops. Implementations
deviate from public documentation.

Change to IA32_PERF_STATUS (0x198) already used in i945/udelay.c
to detect FSB to TSC multiplier.

6bdaaefb30 intel/fsp_rangeley: Use fixed FSB/BCLK value 100 MHz
Prior to commit
  d731a24 src/cpu/intel: Set get_ia32_fsb function common

value of 200 was silently used as a default for fsp_rangeley
(model_406dx) in cpu/x86/lapic/apic_timer:set_timer_fsb().

After the commit, get_ia32_fsb() returns -2, eventually
resulting with divide-by-zero in timer_monotonic_get(), as
get_timer_fsb() returns 0.

Add Rangeley CPUID model 0x4d to get_ia32_fsb() as a fix,
using BCLK = 100 MHz based on the comments in
  northbridge/intel/fsp_rangeley/udelay.c

f9aed65785 cpu/intel/common: decouple IA32_FEATURE_CONTROL lock from set_vmx()
Newer CPUs/SoCs need to configure other features via the
IA32_FEATURE_CONTROL msr, such as SGX, which cannot be done if the
msr is already locked. Create separate functions for setting the
vmx flag and lock bit, and rename existing function to indicate that
the lock bit will be set in addition to vmx flag (per Kconfig).

This will allow Skylake/Kabylake (and others?) to use the common
VMX code without breaking SGX, while ensuring no change in functionality
to existing platforms which current set both together.

Test: build/boot each affected platform, ensure no change in functionality

2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx)
3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx)
