The original version of the mem_chip_info structure does not record rank
information and does not allow precise modeling of certain DDR
configurations, so it falls short on its purpose to compile all
available memory information. This patch updates the format to a new
layout that remedies these issues. Since the structure was introduced so
recently that no firmware using it has been finalized and shipped yet,
we should be able to get away with this without accounting for backwards
compatibility.

DTTS indicated Dynamic Thermal Table Switching.The proposal would like
to develop the schematic for switching 6 thermal table by lid status,
machine body mode and temperature. After entering the OS, the thermal
table would be table A. If the “Motion” or “Lid status change” is
detected. The thermal table would switch to laptop mode or lid close
mode.
Once the higher environment temperatures are detected,the thermal
table would switch to the corresponding power throttle table (B, D or
F). Based on these table switching mechanisms, no matter how the
end-user uses Chromebook,they could enjoy more humanized thermal
designs.
Release Over Over Release .
Temp. Temp. Temp. Temp. .
-------------------------------------------------------- .
Desktop mode Table A Table B 50C 45C .
Lid open (Default) .
-------------------------------------------------------- .
Desktop mode Table C Table D 55C 50C .
Lid close .
-------------------------------------------------------- .
Laptop mode Table E Table F 45C 40C .
-------------------------------------------------------- .
On the proposal, the transmission rules are list below:
1. Table A is the default table after booting.
2. A, C, E (Release Temp) can switch to each other.
3. B, D, F (Over Temp) can switch to each other.
4. A and B, C and D, E and F can switch to each other.
5. If Lid open/close or mode switch event trigger, temperature release
tables will translation to each other, temperature over tables will
translation to each other.After that event trigger, EC will check the
new temperature condition and decide if the temperature need to be
trigger.For example, if table A will switch to table D, table A will
switch to C with Lid close event, if temperature is over 55C, EC will
trigger temperature to switch form table C to D.
6. EC will trigger 3 times body-detection events during power on boot
without any body-mode and lid status change. For this case if the
previous table label is on same group, we will based on the temperature
to decide the table.
For example, assume table A is current table. When the temperature
reaches 50C, than the table is switched from A to B. The current table
is B. When the temperature is downgrade below 45C, the table is
switched form B to A. The same rule is for C and D, E and F.

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.

Presently, coreboot supports two instances of sending EOP cmd to
the Intel CSE.
1. Sending EOP cmd to CSE during `.final` operation from cse pci driver.
2. Starting with Alder Lake, the recommendation was to send EOP to CSE
earlier than CSE `.final` operation. Since then it's referred to as
`Sending EOP Early`. This method helped to save the CSE EOP
response time significantly.
During Meteor Lake platform, CSE EOP response time has become
non-deterministic and we have figured that sending EOP command later
than CSE .final operation is actually helping to optimize the boot time
significantly (around ~150ms savings compared to sending from `.final`
ops and ~5sec compared to sending CSE early).
Hence, this patch intended to create yet another kconfig for sending
CSE late (specifically after `.final` operation). The idea for this
newer config is to use the boot state machine for sending CSE EOP cmd.
The patch train in this series would add the specific changes to allow
sending EOP late and perform other essential operations required prior
booting to OS as coreboot decided to skip calling into FSP Notify phase.
Starting with Jasper Lake, coreboot sends EOP before loading payload
hence, this config is applicable for those platforms.
The current plan is that Intel Jasper Lake, Tiger Lake and Meteor Lake
platform will select this newer config from SoC code.

This also exports cpu_infos from cpu.c as it's a convenient way to get

Later soc/intel/common/smbus addresses TCO2_STS as a separate
16-bit register, while baytrail and braswell assumes 32-bit
wide TCO1_STS to extend as TCO2_STS.
In src/soc/intel/denverton_ns:
#define TCO2_STS_SECOND_TO 0x02
In soc/intel/baytrail,braswell:
#define SECOND_TO_STS (1 << 17)
Elsewehere
#define SECOND_TO_STS (1 << 1)
It's expected that we remove the first (1 << 17) case and only
access TCO2_STS as a separate 16-bit register. For now, use
unique names to avoid confusion.

Tree is inconsistent with the use of TCO register space offsets and
related preprocessor defines. The legacy space was offset from ACPI
PM base by 0x60, but this changed with later platforms. The convenient
way is to define the TCO registers relative to its base address and
subtract 0x60 here, but this change cannot be easily done tree-wide or
in one go.
For the transient period, apply TCO_SPACE_NOT_YET_SPLIT flag until
all platforms use a clean style of tco_{read,write} accessor functions
instead of {read,write}_pmbase16(), or worse, inw/outl().
