The patch fixes the typecasting issue, that is conversion from 'int' to
'unsigned long long int'. This changes value from '0x8000 0000' to
'0xFFFF FFFF 8000 0000'.
During unit testing, the argument is getting changed to an unexpected
number which is resulting to an exception when IA32_HWP_REQUEST MSR is
updated. In this update, the MSR's reserved bits are getting updated, so
this causes exception.
TEST= Verified the code on the Gimble.
No exception is seen after the fix.

To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with
VBOOT_VBNV_FLASH for Haswell.
Currently BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is selected for
CPU_INTEL_HASWELL (see [2]). However, there seems to be no
particular reason on those platforms. Flashconsole works on Broadwell,
at least, and it writes to flash as early as bootblock. Therefore,
remove BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES, so that VBOOT_VBNV_FLASH
can be enabled.

The µcode updates for Broadwell come from coreboot's blobs submodule
and have not been updated in at least 7 years. Use the µcode updates
available in the intel-microcode submodule. This change forgoes some
µcode updates for old Broadwell ULT/ULX steppings with CPUID 0x306d2
and 0x306d3, as well as an old µcode update for Haswell ULT/ULX CPUs
with CPUID 0x40651 in favor of a newer intel-microcode revision that
was already being used: when the µcode updates are concatenated into
one file, the newer µcode update revision would be placed before the
older revision, so the latter would never be used.

Commit 27126f135dad3c0e2f91394e7088b2ff50220146 (cpu/intel/haswell: add
Crystal Well CPU IDs) introduced new Haswell CPUIDs but did not include
any µcode updates for them. It is unknown how this could have worked as
the initial µcode inside the CPU can be quite unstable. Intel CPUs with
support for FIT (Firmware Interface Table) can have their µcode updated
before the x86 reset vector is executed.
The µcode updates for Crystal Well CPUID 0x40661 can be found inside the
intel-microcode submodule. There are no publicly available µcode updates
for Crystal Well CPUID 0x40660 as it is a pre-production stepping, which
is not meant to be used anymore. Hook up the available µcode updates for
Crystal Well CPUs.

There are two types of Haswell/Broadwell platforms: Trad(itional) with
separate CPU and PCH packages, and ULT/ULX where the CPU and PCH share
one package. Mainboards can specify which platform type they are using
the `INTEL_LYNXPOINT_LP` Kconfig option. There are so many differences
between Trad and ULT/ULX that it's not worth doing runtime detection.
The CPUIDs are different for Trad and ULT/ULX platforms, and so are the
µcode updates. So, including Trad µcode updates in a coreboot image for
an ULT/ULX mainboard makes no sense, and vice versa.
Adapt the Makefile so that only relevant µcode updates are added. Also,
add a few comments to indicate which updates correspond to which CPUs.
TEST=Run binwalk on coreboot.rom to verify included µcode updates for:
- Asrock B85M Pro4 (Haswell Trad)
- HP Folio 9480M (Haswell ULT/ULX)
- Purism Librem BDW (Broadwell ULT/ULX)

Prior commit hash 0310d34c2 (cpu/intel/microcode: Have provision to
re-load microcode patch) introduces an option to reload the microcode
based on SoC selecting RELOAD_MICROCODE_PATCH config.
This patch might potentially introduce a boot time regression (~30ms)
when RELOAD_MICROCODE_PATCH kconfig is enabled as all cores might end up
reloading the microcode without the proper need.
Note: RELOAD_MICROCODE_PATCH kconfig is not yet selected by any SoC
hence, it doesn't impact any coreboot project.
The idea is reloading microcode depends on specific use case
(for example: Skip FSP doing MP Init from Alder Lake onwards) hence,
a follow up patch will create a newer API to allow reloading of
microcode when RELOAD_MICROCODE_PATCH config is enabled.

The Intel Firmware Interface Table (FIT) is a bit of an annoying outlier
among CBFS files because it gets manipulated by a separate utility
(ifittool) after cbfstool has already added it to the image. This will
break file hashes created for CBFS verification.
This is not actually a problem when booting, since coreboot never
actually loads the FIT from CBFS -- instead, it's only in the image for
use by platform-specific mechanisms that run before coreboot's
bootblock. But having an invalid file hash in the CBFS image is
confusing when you want to verify that the image is correctly built for
verification.
This patch adds a new CBFS file type "intel_fit" which is only used for
the intel_fit (and intel_fit_ts, if applicable) file containing the FIT.
cbfstool will avoid generating and verifying file hashes for this type,
like it already does for the "bootblock" and "cbfs header" types. (Note
that this means that any attempt to use the CBFS API to actually access
this file from coreboot will result in a verification error when CBFS
verification is enabled.)

When rebuilding coreboot the empty fit table added to added to CBFS
stays the same so the build process sees no reason to update the file.
In the meantime ifittool did update that file for instance to add
microcode update entries. So each time coreboot is rebuilt the entries
are appended to the FIT table which runs out of space at some point.
One way to deal with this is to clear the fit table when setting the
pointer inside the bootblock.
TESTED: Now running 'make' again on prodrive/hermes does not report an
error with a filled FIT table.

This patch aims to make timestamps more consistent in naming,
to follow one pattern. Until now there were many naming patterns:
- TS_START_*/TS_END_*
- TS_BEFORE_*/TS_AFTER_*
- TS_*_START/TS_*_END
This change also aims to indicate, that these timestamps can be used
to create time-ranges, e.g. from TS_BOOTBLOCK_START to TS_BOOTBLOCK_END.

In PARALLEL_MP case enable_lapic() was redundant as it
was already executed prior to initialize_cpu() call.
For the !PARALLEL_MP case enable_lapic() is added to

Selecting CPU_X86_CACHE_HELPER only added the x86_enable_cache wrapper
function around enable_cache which additionally wrote a POST code to
port 0x80 and printed a message to the console. This function was only
called during multi-processor initialization in ramstage via the init
function pointer in the CPU's device operations struct and was run on
all cores, so the message on the console was printed once per CPU core.
This patch replaces all x86_enable_cache calls by calls to enable_cache
and removes the wrapper function and the Kconfig symbol
CPU_X86_CACHE_HELPER which was used to only add this when the
corresponding CPUs used the x86_enable_cache wrapper function.

Since all x86 CPUs in tree have MTRR support, there is no need to guard
the DISPLAY_MTRRS option with HAVE_DISPLAY_MTRRS. Also all x86 CPUs/SoCs
have a display_mtrrs call at least somewhere in their code, so selecting
the DISPLAY_MTRRS option will always have an effect. All SoCs that don't
select RESET_VECTOR_IN_RAM have the postcar stage where it gets called.
The two AMD SoCs that select RESET_VECTOR_IN_RAM use the FSP2 driver
which contains plenty of display_mtrrs calls.

in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added
(cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding
MTRR code selection patch and having verified that all platforms
added the MTRR code on that patch shows that soc/example/min86 and
soc/intel/quark are the only platforms that don't end up selecting the
LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y
which gets overridden to n in the Kconfig of the two SoCs mentioned
above.

All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.
In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs
in their Makefiles.

Each CPU/SoC checks the return value of the mp_init_with_smm and prints
the same error message if it wasn't successful, so move this check and
printk to mp_init_with_smm. For this the original mp_init_with_smm
function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm
function is created which then calls do_mp_init_with_smm, prints the
error if it didn't return CB_SUCCESS and passes the return value of
do_mp_init_with_smm to its caller.
Since no CPU/SoC code handles a mp_init_with_smm failure apart from
printing a message, also add a comment at the mp_init_with_smm call
sites that the code might want to handle a failure.

support for older chipsets, where the size was set to 0 and assumed to
be 2048 bytes. The fix is to change the result of the subtraction to a
signed type, and ensure the following comparison is done without
promoting the signed type to an unsigned one.

Some platforms which have large amounts of RAM and also write-combining
regions may decide to drop the WC regions in favor of the default when
preserving MTRRs for the OS. From a data safety perspective, this is
safe to do, but if, say, the graphics framebuffer is the region that is
changed from WC to UC/WB, then the performance of writing to the
framebuffer will decrease dramatically.
Modern OSes typically use Page Attribute Tables (PAT) to determine the
cacheability on a page level and usually do not touch the MTRRs. Thus,
it is believed to be safe to stop reserving MTRRs for the OS, in
general; PentiumII is the exception here in that OSes that still
support that may still require MTRRs to be available. In any case, if
the OS wants to reprogram all of the MTRRs, it is of course still free
to do so (after consulting the e820 table).

With CBnT a digest needs to be made of the IBB, Initial BootBlock, in
this case the bootblock. After that a pointer to the BPM, Boot Policy
Manifest, containing the IBB digest needs to be added to the FIT
table.
If the fit table is inside the IBB, updating it with a pointer to the
BPM, would make the digest invalid.
The proper solution is to move the FIT table out of the bootblock.
The FIT table itself does not need to be covered by the digest as it
just contains pointers to structures that can by verified by the
hardware itself, such as microcode and ACMs (Authenticated Code
Modules).

CB:49896 added support in `intel_microcode_find()` to cache the found
microcode for faster subsequent accesses. This works okay when the
function succeeds in finding the microcode on BSP. However, if for any
reason, `cpu_microcode_blob.bin` does not contain a valid microcode
for the given processor, then the logic ends up attempting to find
microcode again and again every time it is called (because
`ucode_updates` is set to NULL on failed find, thus retriggering the
whole find sequence every time). This leads to a weird race condition
when multiple APs are running in parallel and executing this
function.
A snippet of the issues observed in the scenario described above:
```
...
microcode: Update skipped, already up-to-date
...
Microcode header corrupted!
...
```
1. AP reports that microcode update is being skipped since the current
version matches the version in CBFS (even though there is no matching
microcode update in CBFS).
2. AP reports microcode header is corrupted because it thinks that the
data size reported in the microcode is larger than the file read from
CBFS.
Above issues occur because each time an AP calls
`intel_microcode_find()`, it might end up seeing some intermittent
state of `ucode_updates` and taking incorrect action.
This change fixes this race condition by separating the logic for
finding microcode into an internal function `find_cbfs_microcode()`
and maintaining the caching logic in `intel_microcode_find()` using a
boolean flag `microcode_checked`.
BUG=b:182232187
TEST=Verified that `intel_microcode_find()` no longer makes repeated
attempts to find microcode from CBFS if it failed the first time.
