Damien Zammit 08ec1ae2c2 mb/intel/d510mo: Explicitly select NIC on PCI in devicetree
While the board configuration still works without this,
It's nicer to have the device statically defined since
the NIC is hardwired to the board.

Lee Leahy 87df8d08d6 soc/intel/quark: Enable Serial Port
Add the code to enable debug serial output using HSUART1:

*  Enable the code using Kconfig value ENABLE_BUILTIN_HSUART1
*  Note that the BIST value is always zero as validated in
   esram_init.inc
*  The initial TSC value is currently not saved!

Testing on Galileo:
*  Edit the src/mainboard/intel/galileo/Makefile.inc file
   *  Add "select ADD_FSP_PDAT_FILE"
   *  Add "select ADD_FSP_RAW_BIN"
   *  Add "select ADD_RMU_FILE"
*  Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
*  Place the pdat.bin files in the location specified by
   CONFIG_FSP_PDAT_FILE
*  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
*  Testing is successful if serial output is present on HSUART1 at
   115200 baud, 8-bit, no parity

Aaron Durbin d87cc3f24e google/chromeos/vboot2: defer clearing rec mode switch
Certain platforms query the recovery mode switch more than just within
vboot during the boot flow. Therefore, it's important that the first call to
get_recovery_mode_switch() is consistent through memory training because
certain platforms use the recovery mode switch to take different action
for memory training. Therefore, defer the clearing of the rec mode
switch to a place when it's known that memory is up and online.

Duncan Laurie 88b28ada69 chromeos: Add vbnv wrapper for the different backends
Add a wrapper around the vbnv implementations and call into the different
backend functions from there.  Also move some of the common functions to
the common code and simplify the backend drivers.  This will allow some
of the code to be re-used so the CMOS backend can backup the data into
the flash backend.

One side effect of this is that the cache of VBNV was removed from CMOS
and EC backends and moved into the VBNV wrapper, but the flash backend
also still has a separate cache because it has more state and complexity
in the implementation.  The wrapper cached data is not used for normal
vbnv_read/vbnv_write because some callers need the ability to force a
write if the backend storage is cleared (i.e. CMOS clear).

On certain systems and CPUs Core Performance Boost (CPB) may cause
sporadic system lockups.  This issue is also somewhat known on the
various proprietary BIOSes, therefore it seems to be a hardware
incompatibility when present.

Allow the user to disable CBP if needed.

Timothy Pearson 31682364ba nb/amd/mct_ddr3: Work around RDIMM training failure
Under certain conditions, not elucidated in the BKDG,
an extra memclock of CAS write latency is required.

The only reliable way I have found to detect when this
is required is to try training without the delay, and
if DQS position training fails, adding the delay and
retraining.

This is probably related in some form or another to
the badly broken DQS Write Early algorithm given
in the BKDG.

Archana Patni 6c1bf27dae intel/skylake: disable ACPI PM Timer to enable XTAL OSC shutdown
Keeping ACPI PM timer alive prevents XTAL OSC shutdown in S0ix
which has a power impact.

Based on a DT variable, this patch disables the ACPI PM timer
late in the boot sequence - disabling earlier will lead to a hang
since the FSP boot flow needs this timer. This also hides the ACPI PM
timer from the OS by removing from FADT table. Once the ACPI PM timer
is disabled, TCO gets switched off as well.

Aaron Durbin 5dbefd9ff6 chromeos/vboot: allow platform to hook into vboot_reboot()
Sometimes it's necessary for the platform to perform clean up
tasks prior to reboot when employing vboot. For example, x86 systems
that resume and do vboot verification may need to clear their
sleep control register prior to doing a cold reset so that the
next boot doesn't appear to be a resume. Allow that hook by
introducing vboot_platform_prepare_reboot().

BUG=chrome-os-partner:46049
BRANCH=glados
TEST=Ensure vboot_platform_prepare_reboot() called from vboot_reboot().

Aaron Durbin 87c9faeb4c chromeos/vboot: provide support for x86 memory init verification
For x86 systems which resume through the reset vector one needs to
ensure the the RW slot taken at resume time matches the one at
boot time. The reason is that any assets pulled out of the boot
media need to match how the platform previously booted. To do
that one needs obtain the hash digest of the chosen slot, and it
needs to be saved in a secure place on the normal boot path. On
resume one needs to retrieve the hash digest back to compare it
with the chosen slot. If they don't match resuming won't be
possible.

BUG=chrome-os-partner:46049
BRANCH=glados
TEST=Suspended and resumed on chell. Also, tested with an EC build
     which returns a bad hash to ensure that is properly caught.
