Added the empty function clear_recovery_mode_switch (weak)
Problem:
If GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC is set,
the following will happen:
1. Boot device in recovery mode with Esc + F3 + Pwr.
2. Turn device off with Pwr button.
3. Turn device on with Pwr button.
Device still boots to recovery screen with
recovery_reason:0x02 recovery button pressed.
If GBB_FLAG_DISABLE_EC_SOFTWARE_SYNC isn't set,
turning the device off and on again
with the Pwr button does a normal boot.
Solution:
Unconditionally clear the recovery flag.

This adds the option to put LPSS and SCC devices into ACPI mode
by saving their BAR0 and BAR1 base addresses in a new device
NVS structure that is placed at offset 0x1000 within the global
NVS table.
The Chrome NVS strcture is padded out to 0xf00 bytes so there
is a clean offset to work with as it will need to be used by
depthcharge to know what addresses devices live at.
A few ACPI Mode IRQs are fixed up, DMA1 and DMA2 are swapped and
the EMMC 4.5 IRQ is changed to 44.
New ACPI code is provided to instantiate the LPSS and SCC devices
with the magic HID values from Intel so the kernel drivers can
locate and use them.
The default is still for devices to be in PCI mode so this does
not have any real effect without it being enabled in the mainboard
devicetree.
Note: this needs the updated IASL compiler which is in the CQ now
because it uses the FixedDMA() ACPI operator.

specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,

This patch implements support for vboot firmware selection. The vboot
support is comprised of the following pieces:
1. vboot_loader.c - this file contains the entry point,
vboot_verify_firmware(), for romstage to call in order to perform
vboot selection. The loader sets up all the data for the wrapper
to use.
2. vboot_wrapper.c - this file contains the implementation calling the vboot
API. It calls VbInit() and VbSelectFirmware() with the data supplied
by the loader.
The vboot wrapper is compiled and linked as an rmodule and placed in
cbfs as 'fallback/vboot'. It's loaded into memory and relocated just
like the way ramstage would be. After being loaded the loader calls into
wrapper. When the wrapper sees that a given piece of firmware has been
selected it parses firmware component information for a predetermined
number of components.
Vboot result information is passed to downstream users by way of the
vboot_handoff structure. This structure lives in cbmem and contains
the shared data, selected firmware, VbInitParams, and parsed firwmare
components.
During ramstage there are only 2 changes:
1. Copy the shared vboot data from vboot_handoff to the chromeos acpi
table.
2. If a firmware selection was made in romstage the boot loader
component is used for the payload.
Noteable Information:
- no vboot path for S3.
- assumes that all RW firmware contains a book keeping header for the
components that comprise the signed firmware area.
- As sanity check there is a limit to the number of firmware components
contained in a signed firmware area. That's so that an errant value
doesn't cause the size calculation to erroneously read memory it
shouldn't.
- RO normal path isn't supported. It's assumed that firmware will always
load the verified RW on all boots but recovery.
- If vboot requests memory to be cleared it is assumed that the boot
loader will take care of that by looking at the out flags in
VbInitParams.
Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as well
by choosing the RO path.

One might wonder what a board named 'build' does. Rename the file to
build-snow. The fact that it is in a directory with google in the name
should be enough to identify the vendor.

AGESA code has wrong definition of CR0_PE bit (1 instead of 0).
PE [Protected Mode Enable] is 0 bit in CR0 register
(If PE=1, system is in protected mode, else system is in real mode)
Bit 1 is MP [Monitor co-processor]
(Controls interaction of WAIT/FWAIT instructions with TS flag in CR0)
System uses CR0_PE define, but I didn't expect any consequences because of this bug.

_RDMSR instruction loads the contents of a 64-bit model specific register (MSR)
specified in the ECX register into registers EDX:EAX.
The EDX register is loaded with the high-order 32 bits of the MSR
and the EAX register is loaded with the low-order 32 bits.
EDX:EAX = MSR[ECX]
So bit 49 will be contained in EDX register.
Buggy code instead of bit 49 (CombineCr0Cd) sets bit [49-32=17] (PfcStrideDis).
PfcStrideDis bit disables stride prefetch generation. This leads to memory
bandwidth loss.

Supermicro H8QGI board
After applying this change i observed huge memory bandwidth increase in tests
that runs on small amount of cores. But unfortunately it doesn't affect
overall bandwidth results on 4P system with 48 cores.
So i think that in this system leading limiting factor is
AMD HT-ASSIST feature (Probe filter).
But right now it is not working. System stucks in Linux boot. I have done
some experiments and figured out that stuck happens when system have cores in
compute unit (CU) other than CU with BSC (boot strap core).
CU is two cores (primary and seconary) that shares some things (L2 cache, FPU ...)
So with probe filter i can boot Linux with one (BSC)
or two (BSC + secondary core in its CU) cores.
And with this configuration i can see memory bandwidth on 1 core (or two cores)
close to original bios.

These were not separable or it would have been two CLs.
Enable CHROMEOS configure option on snow. Write gpio support code for
the mainboard. Right now the GPIO just returns hard-wired values for
"virtual" GPIOs.
Add a chromeos.c file for snow, needed to build.
This is tested and creates gpio table entries that our hardware can use.
Lots still missing but we can now start to fill in the blanks, since
we have enabled CHROMEOS for this board. We are getting further into
the process of actually booting a real kernel.
