It is easier to track CAR_GLOBAL_MIGRATION which is
the approach to be deprecated with the next release.
This change enforces new policy; POSTCAR_STAGE=y is
not allowed together with CAR_GLOBAL_MIGRATION=y.

The common code adheres to the Intel requirement of bringing up the
cores with INIT SIPI SIPI. This sequence is tolerated on some AMD
AMD CPUs but fails on others. Add a way to skip the second SIPI.

Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.

Remove aliasing CONFIG_RESERVED_SMM_SIZE as RESERVED_SMM_SIZE and

It is proper to check cpu turbo mode capability after it is selected
to be enabled. If processor exhibits the presence of hardware support for
turbo, turbo global state will be updated with TURBO_ENABLE. Otherwise,
TURBO_UNAVAILABLE is applied to turbo global state.
TEST=Validated turbo state on GLK and WHL devices.

With VBOOT=y && VBOOT_MEASURED_BOOT=y message
digest will be allocated from the stack and
1 KiB reserve used with the recent platforms
was no longer sufficient.
The comment of LZMA scratchpad consuming stack
was obsolete for postcar, so these can be reduced
to same 4 KiB.

more than 32bit of address space.
Add Documentation as well.
Required for clearing all system memory as part of security API.
Tested on wedge100s:
Takes less than 2 seconds to clear 8GiB of DRAM.
Tested on P8H61M-Pro:
Takes less than 1 second to clear 4GiB of DRAM.

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

Code is based on microcode update procedure from fam10-15h with necessary
microcode blob structure updates for fam16h.
Currently updating microcode in romstage seem to be impossible. AGESA is
overriding the microcode patch regardles of the current microcode revision
patched on CPU. Use ramstage CPU init procedures to update microcode easily.
Tested with microcode blob 07030106 released 2018-02-09 from

This patch removes all possible dependencies in order to build platform
with CONFIG_RAMPAYLOAD enable(without ramstage).
A. Create coreboot separate stage kconfigs
This patch creates seperate stage configs as below
1. HAVE_BOOTBLOCK
2. HAVE_VERSTAGE
3. HAVE_ROMSTAGE
4. HAVE_POSTCAR
5. HAVE_RAMSTAGE
B. Also ensures below kconfigs are aligned with correct stage configs
1. COMPRESS_RAMSTAGE and RELOCATABLE_RAMSTAGE are now enable if
CONFIG_HAVE_RAMSTAGE is selected.
2. COMPRESS_BOOTBLOCK will enable if CONFIG_HAVE_BOOTBLOCK is set
3. COMPRESS_PRERAM_STAGES will enable if CONFIG_HAVE_VERSTAGE
|| CONFIG_HAVE_ROMSTAGE is selected.
C. Also fix compilation issue with !CONFIG_HAVE_RAMSTAGE
On x86 platform:
Case 1: ramstage do exist: CONFIG_HAVE_RAMSTAGE=1
>> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_x86_32
Case 2: ramstage doesn't exist: CONFIG_HAVE_RAMSTAGE=0
>> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_
This patch fixes Case 2 usecase where platform doesn't select
CONFIG_HAVE_RAMSTAGE.
Also add option to create sipi_vector.manual based on $(TARGET_STAGE)
variable.
$(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE
$(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD
