1fe32d6bb2 soc/intel/skylake: Split AC/DC settings for Deep Sx config
Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled
in both DC and AC states.  However since using Deep S3 disables some
expected features like wake-on-USB it is not always desired to enable the
same state in both modes.

To address this split the setting and add a separate config for Deep Sx in
AC and DC states.

All motherboards that set this config were updated, but there is no actual
change in behavior in this commit.

BUG=b:36723679
BRANCH=none
TEST=This commit has no runtime visible changes, I verified on Eve that the
Deep SX config registers are unchanged, and it compiles for all affected boards.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

320edbe2ba vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by default
The virtualized developer switch was invented five years ago and has
been used on every vboot system ever since. We shouldn't need to specify
it again and again for every new board. This patch flips the Kconfig
logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with
CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to
set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the
latter for Lumpy which seems to have been omitted incorrectly, and hide
it from menuconfig since it's a hardware parameter that shouldn't be
configurable.)

Since almost all our developer switches are virtual, it doesn't make
sense for every board to pass a non-existent or non-functional developer
mode switch in the coreboot tables, so let's get rid of that. It's also
dangerously confusing for many boards to define a get_developer_mode()
function that reads an actual pin (often from a debug header) which will
not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set.
Therefore, this patch removes all those non-functional instances of that
function. In the future, either the board has a physical dev switch and
must define it, or it doesn't and must not.

In a similar sense (and since I'm touching so many board configs
anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC.
Instead, it should just be assumed by default whenever a Chrome EC is
present in the system. This way, it can also still be overridden by
menuconfig.

7de031759b soc/intel/skylake: Add SGX initialization
This patch implements SGX initialization steps in coreboot per Intel SGX
BWG rev 2.0.8 for Kaby Lake SoC. If enabled on a Kabylake device, SoC
capability and PRM (processor reserved memory) of desired size (needs to
be configured through PrmrrSize) are provisioned for later software
stack to use SGX (i.e., run SGX enclaves).

One issue is still puzzling and needs to be addressed: by calling
configure_sgx() in cpu_core_init() which is the per-thread function, SGX
is always failing for thread 0 but is successful for other 3 threads.
I had to call configure_sgx() again from soc_init_cpus() which is the
BSP-only function to make it enable on the BSP.

Another pending work is the implementation for the Owner Epoch update
which shall be added later.

BUG=chrome-os-partner:62438
BRANCH=NONE
TEST=Tested on Eve, verified SGX activation is successful on all threads.

b2aac85030 intel/skylake: Add devicetree settings for acoustic noise mitigation
Add options to the skylake chip config that will allow tuning the
various settings that can affect acoustics with the CPU and its VRs.

These settings are applied inside FSP, and they can adjust the slew
slew rate when changing voltages or disable fast C-state ramping on
the various CPU VR rails.

BUG=b:35581264
BRANCH=none
TEST=these are currently unused, but I verified that enabling the
options can affect the acoustics of a system at runtime.

0da186c3ff soc/intel/skylake: indicate voltage margining enabled/disabled
Support for voltage margining is dependent on the platform.
Enabling voltage margining puts additional constraints for
the SLP_S0# to be asserted and hence moving to S0ix state.
If the platform PMIC/VR supports PCH voltage reduction,
voltage marigining can be enabled.

Use the UPD provided by FSP to enable/disable voltage margining.

c248044b20 soc/intel/skylake: Fix broken suspend-resume
With recent change (a4b11e5c90: soc/intel/skylake: Perform CPU MP Init
before FSP-S Init) to perform CPU MP init before FSP-S init, suspend
resume is currently broken for all skylake/kabylake boards. All the
skylake/kabylake boards store external stage cache in TSEG, which is
relocated post MP-init. Thus, if FSP loading and initialization is
done after MP-init, then ramstage is not able to:
1. Save FSP component in external stage cache during normal boot, and
2. Load FSP component from external stage cache during resume

In order to fix this, ensure that FSP loading happens separately from
FSP initialization. Add fsp_load callback for pre_mp_init which ensures
that the required FSP component is loaded/saved from/to external stage
cache.

or a "hyperthreaded"/secondary core. For instance when trying to

2864f85725 intel/skylake: Disable FADT.8042 if NO_FADT_8042 is set
Kernel relies on FADT 8042 flag to enable/disable
8042 interface. If FADT reports 8042 capability and
8042 (/PS2) capability is actually disabled by coreboot,
kernel would assume the presence of 8042 based on the
FADT flag. This results in undesired system power off when
kernel tries to access the 8042 memory region. To address
this, CONFIG_NO_FADT_8042 was added to selectively
disable 8042 on FADT.
