a96e66a76f soc/intel: Clean mess around UART_DEBUG
Everything is wrong here, the Kconfig symbols are only the tip of the
iceberg. Based on Kconfig prompts the SoC code performed pad configu-
rations! I don't see why the person who configures coreboot should have
the board schematics at hand.

As a mitigation, we remove the prompts for UART_DEBUG, which is renamed
to INTEL_LPSS_UART_FOR_CONSOLE (because the former didn't really say
what it's about), and for UART_FOR_CONSOLE in case the former is selec-
ted.

26361862bd soc/intel/apollolake: Add Kconfig switch to enable minimum clock ratio
Add a Kconfig switch to be able to set the CPU clock to the lowest
possible ratio. If enabled the CPU will consume as little power as
possible while providing the lowest performance.

This setting can be overruled by the OS if it has an p-state driver
which can adjust the clock to its need.

2c36889437 soc/intel/common/block/gpio: Allow GPI to be dual-routed
This change adds new macros to GPIO common library helpers to allow
a GPI pad to be dual routed using PAD_CFG_GPI_DUAL_ROUTE. It also adds
a helper macro to configure a pad for IRQ and wake.

Above macros are guarded using a newly added Kconfig option
SOC_INTEL_COMMON_BLOCK_GPIO_DUAL_ROUTE_SUPPORT that is selected only
by SoCs that have been validated to allow dual route of
GPIs. Currently, this config is selected only for APL/GLK/SKL/KBL that
have been validated to work with dual-routing of GPIs for IRQ and
wake.

f677d17ab3 intel: Use CF9 reset (part 2)
Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also
implement board_reset() as a "full reset" (aka. cold reset) as that
is what was used here for hard_reset().

Drop soc_reset_prepare() thereby, as it was only used for APL. Also,
move the global-reset logic.

We leave some comments to remind us that a system_reset() should
be enough, where a full_reset() is called now (to retain current
behaviour) and looks suspicious.

Note, as no global_reset() is implemented for Denverton-NS, we halt
there now instead of issuing a non-global reset. This seems safer;
a non-global reset might result in a reset loop.

6539e10c4f drivers/intel/fsp2_0: Hook up IntelFSP repo
With https://github.com/IntelFsp/FSP/pull/4 merged, this allows using
Intel's FSP repo (that we mirror) to build a complete BIOS ifd region
with a simple coreboot build, automatically drawing in headers and
binaries.

This commit covers Apollolake, Coffeelake, Skylake, and Kabylake.

Skylake is using Kabylake's FSP since its own is FSP 1.1 and Kabylake's
also supports Skylake.

Another candidate (given 3rdparty/fsp's content) is Denverton NS, but
it requires changes to coreboot's FSP bindings to become compatible.

Cannonlake, Whiskeylake require an FSP release.

ef8b95745f src/*/intel/: clarify Kconfig options regarding IFD
HAVE_INTEL_FIRMWARE is used to enable certain options that rely on a valid
Inter Flash Descriptor to exist. It does *not* identify platforms or boards
that are capable of running in descriptor mode if it's valid.
Refine the help text to make this clear.

Introduce a new option INTEL_DESCRIPTOR_MODE_CAPABLE that does simply
declare that IFD is supported by the platform. Select this value everywhere
instead of the HAVE_INTEL_FIRMWARE and default HAVE_INTEL_FIRMWARE to
y if INTEL_DESCRIPTOR_MODE_CAPABLE is selected.

Move the QEMU Q35 special case (deselection of HAVE_INTEL_FIRMWARE) to
the mainboard directory.

c0257dd7ae ifdtool: Add a list of known platforms that support IFD_VERSION_2
ifdtool has relied on one of the fields within FCBA(read_freq) to
determine whether a platform supports IFD_VERSION_1 or
IFD_VERSION_2. However, newer platforms like GLK and CNL do not have
read_freq field in FCBA and so the value of these bits cannot be used
as an indicator to distinguish IFD versions. In the long run, we need
to re-write ifdtool to have a better mapping of SoC to IFD fields. But
until that is done, this change adds a list of platforms that we know
do not support read_freq field but still use IFD_VERSION_2. This
change also updates GLK and CNL to pass in platform parameter to
ifdtool.

5c9df70031 soc/intel/apollolake: enable cache-as-ram paging for glk
Add support and enalbe cache-as-ram paging for glk to work around
a cache-as-ram corruption issue. glk executes verstage, romstage,
and FSP-M directly out of cache-as-ram (just like apl). However,
the front end on glk is very agressive about pulling cache lines
into L1I for potential execution. When the snoops hit in the L1D
and the cache lines are dirty the processor writes the line back.
However, there is no backing store for the dirty lines to go. As
such when the line is pulled back in the value is all 0xff's,
corrupting cache-as-ram.

To fix the issue one needs to enable paging with NX (no execute)
permissions which prevents the above actions from happening because
the TLB will indicate that shouldn't be fetched into the instruction
cache since data will be marked no execute.

The generated page tables are added to cbfs and only added to the
COREBOOT cbfs as they are only consumed in the early cache-as-ram
stages.

The page tables generated with:

$ go run util/x86/x86_page_tables.go \

bd427803ab soc/intel/common/block: Common ACPI
This patch adds the common acpi code.ACPI code is very similar
accross different intel chipsets.This patch is an effort to
move those code in common place so that it can be shared accross
different intel platforms instead of duplicating for each platform.
We are removing the common acpi files in src/soc/intel/common.
This removes the acpi.c file which was previously in
src/soc/common/acpi. The config for common acpi is
SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's
Kconfig file in order to use the common ACPI code. This patch also
includes the changes in APL platform to use the common ACPI block.

TEST= Tested the patch as below:
1.Builds and system boots up with the patch.
2.Check all the ACPI tables are present in
  /sys/firmware/acpi/tables
3.Check SCI's are properly working as we are
  modifying the function to override madt.
4.Extract acpi tables like DSDT,APIC, FACP, FACS
  and decompile the by iasl and compare with good
  known tables.
5.Execute the extracted tables in aciexec to check
  acpi methods are working properly.
