INSTALL and PREFIX variables will not be overwritten. Also, mkdir was
replaced by a tool from the INSTALL variable to be compatible with other
cross-compilation buildsystems (like Yocto).
Overwriting variables generates problems when we use different
buildsystem like Yocto where tool names are stored in environment
variables. This change may make building the utility easier - the user
of different buildsystem will not have to remember to pass correct tool
names when issuing the make command.
Also, this change does not affect the rest of users - if the variable
was not set before, then it will be configured as before.

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.

The intention of CB:69710 was that the expanded config file introduced
there would be a strict superset of the old version and could be used in
all the same cases. This is generally true except for a small oversight:
if a boolean Kconfig is `default y`, but was manually set to `n` by the
user, the new `config` file does not include a line for it. Running
`make olddefconfig` on such a file will again introduce the option as
`y`. It turns out that `make olddefconfig` actually parses those
"load-bearing comments" in that case.
This patch fixes the problem by also generating the minimal defconfig
(like before CB:69710), and then just appending the non-comment lines
from the full config that don't appear in it already. This ensures that
any "load-bearing comments" in the defconfig remain in the file and the
result of Kconfig utilities regenerating a full config from there will
again be the same as before CB:69710. In addition, it clearly separates
the "minimal defconfig" part of the file from the rest, making it easy
for people to extract that if they need it; while also keeping all the
config values in one file to make it easy to grep for a certain value.
Also eliminate that random backslash in the recipe that doesn't seem to
have any good reason to exist and was probably a typo to begin with.

Currently the MRC cache is updated in romstage, immediately after
returning from FSP-M. Since cbmem is not cached in romstage, the update
is slow (~6 ms on nissa). Specifically, the new MRC data returned by the
FSP is stored in the FSP reserved memory in cbmem, so hashing the new
data is slow.
Move the MRC cache update to ramstage, where cbmem is cached. On nissa,
this saves ~5 ms of boot time.
