f4dff389ee cpu/x86/mp_init.c: Set topology on BSP
The BSP might have non-zero lapicid so set the topology accordingly,
without assuming it is 0. This fixes a cpu exception on at least Intel
Meteorlake. This was caused by FSP CPU PPI being giving incorrect
information about the BSP topology.

This problem was introduced by 8b8400a "drivers/fsp2_0/mp_service_ppi:
Use struct device to fill in buffer" which sets the PPI struct based on
struct device.

TESTED on google/rex

177e135136 cpu/x86/topology: Add code to fill in topology on struct path
This is needed to generate MADT and SRAT where lapicid for threads need
to be added last. When CPUID leaf '0xB' is not present assume some
defaults that would result in identical ACPI code generation.

ddf48eb7c7 cpu/mp_init.c: Only enable CPUs once they execute code
On some systems the BSP cannot know how many CPUs are present in the
system. A typical use case is a multi socket system. Setting the enable
flag only on CPUs that actually exist makes it more flexible.

71bc9f0eba cpu/x86/mp_init.c: Generate a C header to get start32 offset
In the current design the relocatable parameters are used to know the
offset of the 32bit startpoint. This requires back and forward
interaction between the stub, the loader and the mp init code. This
makes the code hard to read.

This is static information known at buildtime, so a better way to deal
with this is to generate a header that contains this offset.

3134a81525 cpu/x86/cache: CLFLUSH programs to memory before running
When cbmem is initialized in romstage and postcar placed in the stage
cache + cbmem where it is run, the assumption is made that these are
all in UC memory such that calling INVD in postcar is OK.

For performance reasons (e.g. postcar decompression) it is desirable
to cache cbmem and the stage cache during romstage.

Another reason is that AGESA sets up MTRR during romstage to cache all
dram, which is currently worked around by using additional MTRR's to
make that UC.

TESTED on asus/p5ql-em, up/squared on both regular and S3 resume
       bootpath. Sometimes there are minimal performance improvements
       when cbmem is cached (few ms).

107e7aa0f5 cpu/x86/smm: Enable setting SMM console log level from mainboard
Add a Kconfig RUNTIME_CONFIGURABLE_SMM_LOGLEVEL that enables
mainboard to override mainboard_set_smm_log_level for SMM log level.
This can let SMM have different log level than other stages for
more flexibility.

Another reason is that getting certain data that requires searching
from flash VPD or CMOS is not very ideal to be done in SMM, so in this
change the value can be passed via the member variable in struct
smm_runtime and be referenced directly in SMM.

One example is that mainboard can get the desired SMM log level from
VPD/CMOS, and pass SMM console log level via the variable and in SMM
it can be referenced in get_console_loglevel() override function
directly.

Tested=On OCP Delta Lake, verified SMM log level can be overridden.

2c3ebd8b9d mb,sb,soc/intel: Drop useless IO trap handlers
There are four requirements for the SMI to hit a printk()
this commit now removes.

Build must have DEBUG_SMI=y, otherwise any printk() is a no-op
inside SMM.
ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value.
Platform needs to have IO Trap #3 enabled at IO 0x800.
The SMI monitor must call io_trap_handler for IO Trap #3.

At the moment, only getac/p470 would meet the above criteria
with TRAP(0x32) in its DSDT _INI method. The ASL ignores any
return value of TRAP() calls made.

A mainboard IO trap handler should have precedence over
a southbridge IO trap handler. At the moment we seem to have
no cases of the latter to support, so remove the latter.

7b73e85283 Revert "mb/aopen/dxplplusu: Remove board"
This reverts commit eb76a455cd
and applies minor fixes to make it build again.

PARALLEL_MP was working prior to board removal and no
relevant SMI handlers were implemented. So NO_SMM choice
is now selected.

f874fc2717 cpu/x86/smm/module_loader: Fix ASEG loading
This code was never tested with SSE enabled. Now qemu enables it and
FX_SAVE encroaches on the save states. Without SSE enabled the handler
just happened to be aligned downwards enough to have the save states
fit. With SSE enabled that's not the case. The proper fix is to give the
code setting up stubs the right base address, which is the same as for
the TSEG codepath.
