Since mono_time is now 64-bit, the utility functions interfacing with
mono_time should also be 64-bit so precision isn't lost.

The X2APIC_LATE_WORKAROUND kconfig allows bringing APs in XAPIC mode initially hence, it won't work if LAPIC ID is > 0xff.
This patch ensures the MAX_CPUS logic is appropriate while selecting X2APIC_LATE_WORKAROUND kconfig from SoC.

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.

When switching to different board, 'make clean' needs to happen because
not everything gets properly regenerated. Microcode updates are among
those. You could end up with the microcode updates from the previous
build which can be incorrect. Adding $(DOTCONFIG) as a dependency which
gets updated when you change something in Kconfig fixes this.
TESTED: swap between boards that use different microcode and see that
the size changes.

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.)

This code was hard to read as it did too much and had a lot of state
to keep track of.
It also looks like the staggered entry points were first copied and
only later the parameters of the first stub were filled in. This
means that only the BSP stub is actually jumping to the permanent
smihandler. On the APs the stub would jump to wherever c_handler
happens to point to, which is likely 0. This effectively means that on
APs it's likely easy to have arbitrary code execution in SMM which is a
security problem.

This code is much easier to read if one does not have to keep track of
mutable variables.
This also fixes the alignment code on the TSEG smihandler setup code.
It was aligning the code upwards instead of downwards which would cause
it to encroach a part of the save state.

Currently no smihandler uses heap.
coreboot's heap manager also is quite limited in what it will
free (only the latest alloc). This makes it a bad idea to use it inside
the smihandler, as depending on the alloc usage the heap might actually
be full at some point, breaking the smihandler.
This also reduces the ramstage by 448 bytes on google/vilboz.

MTRR is a core level register which means 2 threads in one core share
same MTRR. There is a race condition could happen that AP overrides
BSP MTRR unintentionally.
In order to prevent such race condition between BSP and APs, this
patch provides a function to let BSP assign tasks to all APs and wait
them to complete the assigned tasks.

This patch migrates a few useful MTRR functions as below from
`earlymtrr.c` file to newly created common stage file `mtrrlib.c`.
1. get_free_var_mtrr
2. set_var_mtrr
3. clear_all_var_mtrr
These functions can be used to perform the MTRR programming from IA
common code SPI driver as `fast_spi.c` without requiring two separate
implementations for early boot stage (till romstage) and for ramstage
onwards.

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 change provides hooks for the SoC so it can perform any
initialization and cleanup in the SMM handler.
For example, if we have a UART enabled firmware with DEBUG_SMI, the UART
controller could have been powered off by the OS. In this case we need
to power on the UART when entering SMM, and then power it off before we
exit. If the OS had the UART enabled when entering SMM, we should
snapshot the UART register state, and restore it on exit. Otherwise we
risk clearing some interrupt enable bits.

This change will allow the SMI handler to write to the cbmem console
buffer. Normally SMIs can only be debugged using some kind of serial
port (UART). By storing the SMI logs into cbmem we can debug SMIs using
`cbmem -1`. Now that these logs are available to the OS we could also
verify there were no errors in the SMI handler.
Since SMM can write to all of DRAM, we can't trust any pointers
provided by cbmem after the OS has booted. For this reason we store the
cbmem console pointer as part of the SMM runtime parameters. The cbmem
console is implemented as a circular buffer so it will never write
outside of this area.

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.

This reverts commit ceaf959678905f44a54a116f37bd15acab5d4608.
The AMD Picasso SoC doesn't support x2APIC and neither advertises the
presence of its support via bit 21 in EAX of CPUID leaf 1 nor has the
bit 10 in the APIC base address MSR 0x1b set, but it does have 0xd CPUID
leaves, so just checking for the presence of that CPUID leaf isn't
sufficient to be sure that EDX of the CPUID leaf 0xb will contain a
valid APIC ID.
In the case of Picasso EDX of the CPUID leaf 0xb returns 0 for all cores
which causes coreboot to get stuck somewhere at the end of MP init.
I'm not 100% sure if we should additionally check bit 21 in EAX of CPUID
function 1 is set instead of adding back the is_x2apic_mode check.
TEST=Mandolin with a Picasso SoC boots again.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'
