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.

As per ME BWG, there are two mechanism to generate a Global
Reset (resets both host and Intel ME), one is through CF9h
IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set,
PMC PCI offset ACh[20]. Another is to issue the Global Reset
MEI message. Because any attempts to cause global reset without
synchronizing the two sides might cause unwanted side effects,
such as unwritten flash data that will get destroyed if the
host were to cause a global reset without informing Intel ME
firmware, the recommended method is to send a Global Reset MEI
message when the following conditions are met:
The PCH chipset firmware just needs to complete the Intel ME
Interface #1 initialization and check the Intel ME HFSTS state
if Intel ME is not in ERROR state and is accepting MEI commands
then firmware should be able to use Global Reset MEI message to
trigger global reset.
Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9
write of 0x06 or 0x0E command with PCH ETR3 register bit [20]
to perform the global reset.
BUG=none
BRANCH=none
TEST=Verified Global Reset MEI message is able to perform platform

Add a PCI driver for the skylake SD card device and have it generate
an entry in the SSDT for the card detect GPIO if it is provided by the
mainboard in devicetree.
This sets up a card detect GPIO configuration that will trigger an
interrupt on both edges with a 100ms debounce timeout and can wake the
SD controller from D3 state.
The GpioInt() entry is bound to the "cd-gpio" device property which will
be consumed by the kernel driver.
The resulting ACPI output in the SSDT will be combined with the SDXC
device declaration in the DSDT.
Example:
Scope (\_SB.PCI0.SDXC)

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.

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.

Aaron Durbin found that soc/common is already included as a subdir via
the wildcard in Makefile.inc:
subdirs-y += $(wildcard src/soc/*/*)
Since the entire file is protected by CONFIG_SOC_INTEL_COMMON, there
is no problem with including it for every platform. On the other hand,
when it is included by the skylake and braswell makefiles, any rule is
duplicated. As a result fix the braswell and skylake makefiles.

Many Kconfig options changed in coreboot.org since
skylake was first started. Fix Kconfig option name
changes, and also provide a common option, UART_DEBUG
that can be selected to select all the necessary
options.
Note: It's still a requirement to manually unset the
8250IO option because that's unconditionally set.
