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.

that will need to be implemented before it is enabled.
3) enable scc_acpi_mode and see EMMC and SDCard devices detected by

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
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,
romstage, and ramstage.

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.

_RDMSR instruction loads the contents of a 64-bit model specific register (MSR)

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

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.

Add needed prototypes to .h files.
Remove unused variables and fix types in printk statements.
Add #IFNDEFs around #DEFINEs to keep them from being defined twice.
Fix a whole bunch of casts.
Fix undefined pre-increment behaviour in a couple of macros. These now
match the macros in the F14 tree.
Change a value of 0xFF that was getting truncated when being assigned
to a 4-bit bitfield to a value of 0x0f.
This was tested with the torpedo build.
This fixes roughly 132 of the 561 warnings in the coreboot build
so I'm not going to list them all.

Add a prototype to a .h file
Remove an unused file (GppHp.c) from the build by deleting it from the
makefile. I left the file since this is vendorcode. This is the code
for PCIe hotplug.
Inside GppHp.c, make functions not called from outside static.
This obviously isn't important since the file isn't used, but for
the sake of the cleanup I thought I'd go ahead with it...
This was tested with the torpedo build.

In the AGESA routine GfxInitSview() called in the S3save path,
the IO Space bit was getting cleared from the command register.
This kept seabios from initializing the video bios. If the vbios
was loaded by coreboot, this routine was skipped, allowing seabios
to initialize vbios as well. I have modified the routine to save
and restore the command register instead of clearing the IO Space
bit.

The Number of Ports register says that it should be set to the maximum
number of ports supported by the silicon. AGESA was setting this to be
the number of enabled ports. If port 1 was the only port with a drive,
this value got set to 0, indicating 1 port. This causes SeaBIOS to only
look at port 0 and quit, never finding the drive on port 1.
Dave Frodin: I also verified that this patch allows a SATA drive plugged
into port 2 to be detected without a device in port 1.

Success return value in DMI functions GetDmiInfoMain(..) and GetType4Type7Info(...) of AGESA vendorcode is "Flag = TRUE".
This results in a failure of init late function:
"agesawrapper_amdinitlate failed: 1"
It happens because TRUE = 1 = AGESA_UNSUPPORTED.
Replacing TRUE with AGESA_SUCCESS (= 0) fixes this problem.
Only family f15tn does not have such bug.
This patch just replaces TRUE with AGESA_SUCCESS, but maybe all DMI functions should be copied from Trinity family?

- Allows for no fan control, manual setup of SB800 Fan registers, or
setup of the IMC fan configuration registers.
- Register configuration is done through devicetree.cb. No files need
to be added for new platform configuration.
- Initial setup is for Persimmon, but may be extended to any cimx/sb800

This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.
This change sets up the communication, but doesn't act on it just yet.
Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.
