Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.
We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

- C-state table based on static config
MWAIT values are from ref code for non-S0ix config
C6 substate 8 is ignored by the kernel as it violates the CPUID
but it is left in as the other substate may not work.
- P-state table generated with proper ratio and VID values
relies on having the package power msr set to magic value
as the power-on default is wrong
- T-state table uses static table

Start using the rmodtool for generating rmodules.
rmodule_link() has been changed to create 2 rules:
one for the passed in <name>, the other for creating
<name>.rmod which is an ELF file in the format of
an rmodule.
Since the header is not compiled and linked together
with an rmodule there needs to be a way of marking
which symbol is the entry point. __rmodule_entry is
the symbol used for knowing the entry point. There
was a little churn in SMM modules to ensure an
rmodule entry point symbol takes a single argument.

When the southcluster pci devices are listed in the devicetree add
the ability to perform the proper disabling sequence for turning
off devices. This only turns off the pci device interface as well
as put the device into D3Hot. It is not yet known how to put the TXE
device into D3Hot so it's currently not possible to disable that
device.
Also, expose the southcluster_enable_dev() function so that other
devices can call this if they require doing specific things before
disabling the device. The southcluster_enable_dev() is only called
on devices found in the devicetree and if they currently have no

With the recent improvement 3d6ffe76f8a505c2dff5d5c6146da3d63dad6e82,
speedup by CACHE_ROM is reduced a lot.
On the other hand this makes coreboot run out of MTRRs depending on
system configuration, hence screwing up I/O access and cache
coherency in worst cases.
CACHE_ROM requires the user to sanity check their boot output because
the feature is brittle. The working configuration is dependent on I/O
hole size, ram size, and chipset. Because of this the current
implementation can leave a system configured in an inconsistent state
leading to unexpected results such as poor performance and/or
inconsistent cache-coherency
Remove this as a buggy feature until we figure out how to do it properly
if necessary.

There are 2 methods currently available in coreboot to load
ramstage from romstage: cbfs and vboot. The vboot path had
to be explicitly enabled and code needed to be added to
each chipset to support both. Additionally, many of the paths
were duplicated between the two. An additional complication
is the presence of having a relocatable ramstage which creates
another path with duplication.
To rectify this situation provide a common API through the
use of a callback to load the ramstage. The rest of the
existing logic to handle all the various cases is put in
a common place.

Set the BSP to operate at max frequency early in romstage.
The call to punit_init() is when the frequency actually ramps as
that makes the punit actually start working.
BUG=chrome-os-partner:22857
BRANCH=None
TEST=Built and booted. Noted operating frequency status is max.

The caching policy for romstage was previously using a 32KiB
of cache-as-ram for both the MRC wrapper and the romstage stack/data.
It also used a 32KiB code cache region. The BWG's limitations for
the code and data region before memory is up was wrong. It consists
of a 16-way set associative 1MiB cache. As long as enough addresses
are not read there isn't a risk of evicting the data/stack.
Now create a 64KiB cache-as-ram region split evenly between romstage
and the MRC wrapper. Additionally cache the memory just below
4GiB in CBFS size. This will cover any code and read-only data needed.

TEST=Manual. Enable GPIO_DEBUG and verify pad registers are set
according to expectation. Also verify bayleybay still boots to payload

The punit is responsible for a number of things. Without
performing the sequence included it won't change processor
frequency when requested and apparently there are some bizarre
hangs introduced if this sequence isn't included either. Lastly,
this needs to come after microcode has been loaded. As that is
done in bootblock the ordering is correct.
One other side effect is that this fixes the graphics devices'
device id. Before it was showing up as the same device id of the
SoC transaction router.

patch).

The TCO timer always starts ticking out of reset.
However, depending on microcode loading and punit
initialization the TCO timing out has a different
impact on the sytem. Without loading microcode
or initializing the punit the tco times out and
nothing happens. However, when microcode is loaded
a timeout will reset the system. Lastly, if the
punit is initialized but the microcode isn't loaded
the TCO timeout will shut down the system.
To fix all the weird symptoms disable the TCO.
BUG=chrome-os-partner:22858
BRANCH=None
TEST=Built and booted with microcode loading. Reset doesn't
occur.
