The offset of the device_nvs in the gnvs struct is expected to be
0x1000. It is actually 0x100 so padding is needed to move device_nvs
to the expected location. ACPI references to device_nvs objects will
be correct with the padding.
This was tested using a Micro Industries customized Baytrail-I board
based on the Intel Bayley Bay CRB. In intel/baytrail/nvs.h, there's
a Google customized structure located at 0x0100-0x0FFF that is
removed from the fsp_baytrail/nvs.h which explains the mismatch here.

ACPI globalnvs.asl expects the gnvs memory area size to be 0x2000.
Padding has been added to device_nvs struct to reserve the full
0x2000 bytes for gnvs usage.
No known issues are caused by having the GNVS area shorter than
what ACPI thinks. Since there's nothing defined in this area,
O/S shouldn't try to access it. Only problem might be if O/S
notices the SSDT is located within the GNVS defined area.
I verified that the next table written to memory (SSDT) is 0x2000

Zero out the GNVS area so that uninitialized portions are defined.
Tests using Microsoft Windows (XP/7/8) gave a bluescreen bugcheck: A5
(ACPI_BIOS_ERROR) with the first parameter (0x00001000)
(ACPI_BIOS_USING_OS_MEMORY). Some ACPI enumerated devices use the
GNVS area to define whether they're enabled and their MMIO regions.
On my custom baytrail-based board and build, these devices were
disabled but GNVS had uninitialized data indicating the devices
were enabled with improper MMIO regions.
Should investigate further to see where the GNVS device values are
set if enabled and make sure they're set to valid values even when
the devices are disabled via the mainboard/devicetree.cb.

- Obviously, uses the FSP instead of the MRC binaries.
- FSP does additional hardware setup, so coreboot doesn't need to.
- Different microcode & microcode loading method
- Uses the cache_as_ram.inc from the FSP Driver
- Various other changes in support of the FSP
Additional changes that don't have to to with the FSP vs MRC:
- Updated IRQ Routing
- Different FADT implementation.

This improves boot time in 2 ways for a firmware upgrade:
1. Normally MRC would detect the S0 state without an MRC cache
even though it's told to the S5 path. When it observes this
state a cold reset occurs. The cold reset stays in S5 for
at least 4 seconds which is time observed by the end user.
2. As the EC was running RW code before the reset after firmware
upgrade it will still be running the older RW code. Vboot will
then reboot the EC and the whole system to put the EC into RO
mode so it can handle the RW update.
The issues are mitigated by detecting the system is in S0 with
no MRC cache and the EC isn't in RO mode. Therefore we can do the
reboot without waiting the 4 secs and the EC is running RO so
the 2nd reboot is not necessary.

The memory reference code doesn't maintain some of
the registers which contain valuable information in order
to log correct reset and wake events in the eventlog. Therefore
snapshot the registers which matter in this area so that
they can be consumed by ramstage.
BUG=chrome-os-partner:24907
BRANCH=rambi,squawks
TEST=Did various resets/wakes with logging patch which
consumes this structure. Eventlog can pick up reset
events and power failures.
