Aaron Durbin 76d16715ec skylake: add global reset cause registers to power state
Log the global reset causes in the power state structure.
While working in there pack the struct and use width-specific
types as this struct crosses the romstate <-> ramstage boundary.
Lastly, remove hsio version as it wasn't being written or read.

After global reset induced:
PM1_STS:   0000
PM1_EN:    0000
PM1_CNT:   00000000
TCO_STS:   0000 0000
GPE0_STS:  00000000 00000000 00000000 00000000
GPE0_EN:   00000000 00000000 00000000 00000000
GEN_PMCON: d8010200 00003808
GBLRST_CAUSE: 00000000 00040004
Previous Sleep State: S0

BUG=None
BRANCH=None
TEST=Induced global reset on glados using ETR3 register and write
     to cf9.

coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary BIOS
(firmware) found in most computers.  coreboot performs a little bit of
hardware initialization and then executes additional boot logic, called a
payload.

With the separation of hardware initialization and later boot logic,
coreboot can scale from specialized applications that run directly
firmware, run operating systems in flash, load custom
bootloaders, or implement firmware standards, like PC BIOS services or
UEFI. This allows for systems to only include the features necessary
in the target application, reducing the amount of code and flash space
required.

coreboot was formerly known as LinuxBIOS.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://www.coreboot.org/Payloads for a list of supported payloads.


Supported Hardware
------------------

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)
 * ncurses (for 'make menuconfig')
 * flex and bison (for regenerating parsers)


Building coreboot
-----------------

Please consult http://www.coreboot.org/Build_HOWTO for details.


Testing coreboot Without Modifying Your Hardware
------------------------------------------------

If you want to test coreboot without any risks before you really decide
to use it on your hardware, you can use the QEMU system emulator to run
coreboot virtually in QEMU.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:

You can contact us directly on the coreboot mailing list:
