Add the missing 'b' to the 4gb so that get_top_of_mem_above_4gb is in

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.

This moves the definition for POST_BOOTBLOCK_CAR from the intel-specific
postcodes into the common postcode list, and uses it for the
cache-as-RAM init as needed.

Because POST_BOOTBLOCK_CAR was set to 0x20 in some spots and 0x21 in
most of the others, the values were consolidated into 0x21.  This will
change the value on some platforms.

Any conflicts should get sorted out later in the conversion process.

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.

c87ab01c2d cpu/intel/car: Define post codes
This moves a lot of post code values, but unifies them between
platforms, so that the same value means the same thing as much as
possible.

The P4-netburst code was the most extensive and most different, so that
dictated the majority of the values.  Three were two values there that
didn't match the other files, so those two values, 0x22 & 0x29 have
duplicate entries in the table.

The rest of the entries are similar between platforms, though the values
for many of them were moved to match the P4-netburst values.

POST_BOOTBLOCK and POST_POSTCAR values are intended to eventually become
global, while POST_SOC would be specific to the Intel platforms.

56776a1ab3 soc/amd: Do SMM relocation via MSR
AMD CPUs have a convenient MSR that allows to set the SMBASE in the save
state without ever entering SMM (e.g. at the default 0x30000 address).
This has been a feature in all AMD CPUs since at least AMD K8. This
allows to do relocation in parallel in ramstage and without setting up a
relocation handler, which likely results in a speedup. The more cores
the higher the speedup as relocation was happening sequentially. On a 4
core AMD picasso system this results in 33ms boot speedup.

TESTED on google/vilboz (Picasso) with CONFIG_SMI_DEBUG: verify that SMM
is correctly relocated with the BSP correctly entering the smihandler.

Files that were written specifically for coreboot and don't have license

overall coreboot project.

Files that were sourced from Linux are similarly GPL-2.0-only.

The cpu/power files were committed with source that was licensed as
GPL-2.0-or-later, so presumably that's the license for that entire

The final file, vbe.h gives a pointer to the BSD-2-Clause license
