026003e621 skylake: Add Audio DSP device
Add the Audio DSP device for skylake as a PCI driver with a static
scan_bus handler so generic devices can be declared under it.

This is for devices like the Maxim 98357A which is connected on the
I2S bus for data but has no control channel bus and instead just has
a GPIO for channel selection and power down control and needs to
describe that GPIO connection to the OS via ACPI.

0d8bb7427b skylake: Add I2C devices
Add the I2C devices to skylake with the scan_bus handler for SMBUS
devices so that I2C-based devices can be declared in devicetree.cb
and get initialized properly during ramstage.

This does not yet provide the I2C driver, but it allows for devices
that are declared in devicetree.cb to provide ACPI tables to the OS.

df21440d68 intel/skylake: provide default VR configuration
FSP 1.8.0 will do nothing with the VR settings if VrConfigEnable is
non-zero. That behavior is not desired because it's not clear what
the behavior will be for various processor SKUs. Instead provide
default values for the VR config. Note that PSI3 and PSI4 are not
enabled for those defaults.

df13c31ed6 intel/skylake: During RO mode after FSP reset CB lose original state
CB used to clear recovery status towards romstage end after FSP
memory init. Later inside FSP silicon init due to HSIO CRC mismatch
it will request for an additional reset.On next boot system resume
in dev mode rather than recovery because lost its original state
due to FSP silicon init reset.

Hence an additional 1 reset require to identify original state.
With this patch, we will get future platform reset info during romstage
and restore back recovery request flag so, in next boot CB can maintain
its original status and avoid 1 extra reboot.

ed8a723f42 intel/skylake: add nhlt support
The use of a NHLT table is required to make audio work
on the skylake SoCs employing the internal DSP. The table
describes the audo endpoints (render vs capture) along with
their supported formats. These formats are not only dependent
on the audio peripheral but also hardware interfaces. As such
each format has an associated blob of DSP settings to make
the peripheral work. Lastly, each of these settings are provided
by Intel and need to be generated for each device's hardware
connection plus mode/format it supports. This patch does not
include the dsp setting blobs.

The current supported connections:
- digital mic array 2 channel
- digital mic array 4 channel
- Maxim 98357 amplifier
- ADI ssm4567
- NAU88L25 headset codec

490006bf7d intel/skylake: Work around ROMCC optimization bug
On Skylake systems, the bootblock fails to compile with the following
error message:

bootblock_simple.c:6.1:
0x13930e0 copy       Internal compiler error: non dominated rhs use point
0x13a3f70?
Aborted (core dumped)

The option -fno-simplify-phi works around the issue, but will cause the
code to use more registers, hence we also need to enable -mcpu=p4 (see
intel/truxton mainboard for another example of where this has been done
in the past)

789f2b6c43 fsp1_1: provide binding to UEFI version
FSP has some unique attributes which makes integration
cumbersome:

1. FSP header files do not include the types they need. Like
   EDKII development it's expected types are provided by the
   build system. Therefore, one needs to include the proper
   files to avoid compilation issues.
2. An implementation of FSP for a chipset may use different
   versions of the UEFI PI spec implementation. EDKII is a
   proxy for all of UEFI specifications. In order to provide
   flexibility one needs to binding a set of types and
   structures from an UEFI PI implementation.
3. Each chipset FSP 1.1 implementation has a FspUpdVpd.h
   file which defines it's own types. Commonality between
   FSP chipset implementations are only named typedef
   structs. The fields within are not consistent. And
   because of FSP's insistence on typedefs it makes it
   near impossible to forward declare structs.

The above 3 means one needs to include the correct UEFI
type bindings when working with FSP. The current
implementation had the SoC picking include paths in the
edk2 directory and using a bare <uefi_types.h> include.
Also, with the prior fsp_util.h implementation the SoC's
FSP FspUpdVpd.h header file was required since for providing
all the types at once (Generic FSP 1.1 and SoC types).

The binding has been changed in the following manner:
1. CONFIG_UEFI_2_4_BINDING option added which FSP 1.1
   selects. No other bindings are currently available,
   but this provides the policy.
2. Based on CONFIG_UEFI_2_4_BINDING the proper include
   paths are added to the CPPFLAGS_common.
3. SoC Makefile.inc does not bind UEFI types nor does
   it adjust CPPFLAGS_common in any way.
4. Provide a include/fsp directory under fsp1_1 and
   expose src/drivers/intel/fsp1_1/include in the
   include path. This split can allow a version 2,
   for example, FSP to provide its own include files.
   Yes, that means there needs to be consistency in
   APIs, however that's not this patch.
5. Provide a way for code to differentiate the FSP spec
   types (fsp/api.h) from the chipset FSP types
   (fsp/soc_binding.h). This allows for code re-use that
   doesn't need the chipset types to be defined such as
   the FSP relocation code.

3953e3947d x86: bootblock: remove linking and program flow from build system
The build system was previously determining the flow
and linking scripts bootblock code by the order of files
added to the bootblock_inc bootblock-y variables.Those
files were then concatenated together and built by a myriad of
make rules.

Now bootblock.S and bootblock.ld is added so that bootblock
can be built and linked using the default build rules.
CHIPSET_BOOTBLOCK_INCLUDE is introduced in order to allow the
chipset code to place include files in the path of the bootblock
program -- a replacement for the chipset_bootblock_inc
make variable.
