Since multiple boards will be living within one directory move all
the macros for defining anyting related to GPIOs to the gpio.h
header file. That way, when other boards land they can override
or use them as is.

There's no common EC header file in the code base, and I didn't
want to use a header file for single declaration. Therefore,
just move the declaration to each file that uses that symbol.

To further the ability of multiple variant boards to share code
provide a place to land the split up changes. This patch provides
the tooling using a new Kconfig value, VARIANT_DIR, as well as
the Make plumbing. The directory layout with a single variant,
reef (which is also the baseboard), looks like this:
variants/baseboard - code
variants/baseboard/include/baseboard - headers
variants/reef - code
variants/reef/include/variant - headers
New boards would then add themselves under their board name
within the 'variants' directory.
No split has been done with providing different logic yet.
This is purely a organizational change.

Before, we calculate the pwm duties for cpu cores and centerlogic by
hand, adding pwm_regulator.c to handle this. The default pwm design
min/max voltage may be different between revs.
With the pwm regulator, this patch changes the little cpu frequency from
600M to 1512M, and raises CPU voltage to 1.2V correspondingly.
This also means we decide to drop the ES1 because it may fail to

Add Initial pieces of code to support fsp2.0 in skylake keeping
the fsp1.1 flow intact.
The soc/romstage.h and soc/ramstage.h have a reference to
fsp driver includes, so split these header files for
each version of FSP driver.
Add the below files,
car_stage.S:
Add romstage entry point (car_stage_entry).
This calls into romstage_fsp20.c and aslo handles
the car teardown.
romstage_fsp20.c:
Call fsp_memory_init() and also has the callback
for filling memory init parameters.
Also add monotonic_timer.c to verstage.
With this patchset and relevant change in kunimitsu mainboard,
we are able to boot to romstage.

On i945 the vram size is the default 8mb. It is also possible
to set it 1mb or 0mb hardcoding the GGC register in early_init.c
The intel documentation on i945, "Mobile Intel® 945 Express Chipset
Family datasheet june 2008" only documents those three options.
They are set using 3 bits. The documententation also makes mention
of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it.
The other non documented (straight forward) bit combinations allow
to change the VRAM size to those other states.
What this patch does is:
- add those undocumented registers with their respective vram size to
the i945 NB code;
- make this a cmos option on targets that have this northbridge.
TEST: build, flash to target, set cmos as desired and boot linux.
On Debian it can be found using "dmesg | grep stolen".
NOTE: dmesg message about reserved vram are quite different depending
on linux version

If ramstage caching outside CBMEM is enabled
i.e CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM, then a
helper function to determine the caching region in SMM
should be implemented. Add the same to FSP2.0 driver.
FSP1.1 driver had the same implementation hence copied stage_cache.c.
The SoC code should implement the smm_subregion to provide
the base and size of the caching region within SMM. The fsp/memmap.h
provides the prototype and we will reuse the same from FPS 1.1.

Currently boards based on fsp_broadwell_de fail to compile if the config
switch CONFIG_DEBUG_SPI_FLASH is selected. The error is caused by the
usage of const for the address pointer in the functions writeb_, writew_
and writel_. The reason why it stayed hidden for so long is the fact that
the switch is used with the preprocessor and nobody really selects it
until there is a bug one want to find in this area.
This patch fixes the parameter type definition which solves the error.
In addition the config switch is not used on preprocessor level anymore
but instead on compiler level. This ensures that at least the code
syntax is checked on build time even if the config option is not
selected. Also prefix the messages with "SPI:" to make them more
meaningful in a full log.

for its needs. An unset value in devicetree results in a conservative

The current CBMEM code contains an optimization that maintains the
structure with information about the CBMEM backing store in a global
variable, so that we don't have to recover it from cbmem_top() again
every single time we access CBMEM. However, due to the problems with
using globals in x86 romstage, this optimization has only been enabled
in ramstage.
However, all non-x86 platforms are SRAM-based (at least for now) and
can use globals perfectly fine in earlier stages. Therefore, this patch
extends the optimization on those platforms to all stages. This also
allows us to remove the requirement that cbmem_top() needs to return
NULL before its backing store has been initialized from those boards,
since the CBMEM code can now keep track of whether it has been
initialized by itself.

This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.
Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'
file processor.

This patch adds support for the CBFS attributes that were already
introduced in cbfstool and libpayload. I'm only copy&pasting the header
definitions needed for this once more. Really, we should be unifying the
definitions (and possibly part of the code) from cbfstool with
commonlib, but apparently that hadn't been done when this feature was
introduced and I don't really have time to do it cleanly now.
Also add a function to extract info from the compression attribute,
which can then be used to run cbfs_load_and_decompress() on the file.

This enables the C4 low power state on the lenovo x200 and t400.
It's inspired by the thread on the mailinglist:
"[coreboot] Lenovo X200 running Coreboot drains 3-4W more power
than with Vendor BIOS".
What this does, is to enable a C3 state using MWAIT(C3) request
and set the southbridge config c4onc3_enable to automatically
upgrade C3 to the lower power C4 state.
The latency (0x37) is the same value used by the vendor bios.
With C4 enabled the idle power consumption is about ~2-3W lower.
TEST= build and install on target. Use powertop top to measure power
usage. To manually disable c-state to compare them,
do (tested on linux 4.4):
echo 1 > /sys/devices/system/cpu/cpu*/cpuidle/stateX/disable

Some SB700-based systems and ROMs support high speed (33MHz) SPI
access instead of the power-on default 16.5MHz. Add an option
to enable high speed SPI access in the bootblock, and set the
default value to Disabled. This greatly decreases boot time on
SB700-based systems, especiall when a large payload is in use.
On a KGPE-D16 with a Petitboot (Linux + initramfs) payload, the
command prompt was accessible within 20 seconds of power on, which
incidentally is faster than the proprietary BIOS on the same machine
could even reach the GRUB bootloader.

On x86 platforms, google_chromeec_early_init() is used to put the EC
into RO mode when there's a recovery request. This is to avoid training
memory multiple times when the recovery request is through an EC host
event while the EC is running RW code. Under that condition the EC will
be reset (along with the rest of the system) when the kernel verification
happens. This leads to an execessively long recovery path because of the
double reboot performing full memory training each time.
By putting this logic into the verstage program this reduces the
bootblock size on the skylake boards. Additionally, this provides the
the correct logic for all future boards since it's not tied to FSP
nor the mainboard itself. Lastly, this double memory training protection
works only for platforms which verify starting from bootblock. The
platforms which don't start verifying until after romstage need to
have their own calls (such as haswell and baytrail).

The SPI drivers for the various chipsets are not consistent in
their handling of when they are accessible. Coupled with the
unknown ordering of boot_device_init() being called this can
lead to unexpected behavior (probing failures or hangs). Instead
move the act of initializing the SPI flash boot device to when
the various infrastructure requires its usage when it calls
boot_device_rw(). Those platforms utilizing the RW boot device
would need to ensure their SPI drivers are functional and
ready when the call happens.
This further removes any other systems failing to boot as
reported in https://ticket.coreboot.org/issues/67.
