All current implementations of ramstage_cache_invalid() were just
resetting the system based on the RESET_ON_INVALID_RAMSTAGE_CACHE
Kconfig option. Move that behavior to a single implementation
within prog_loaders.c which removes duplication.

Without RELOCATABLE_RAMSTAGE have WB cache large enough
to cover the greatest ramstage needs, as there is no benefit
of trying to accurately match the actual need. Choose
this to be bottom 16MiB.
With RELOCATABLE_RAMSTAGE write-back cache of low ram is
only useful for bottom 1MiB of RAM as a small part of this gets used
during SMP initialisation before proper MTRR setup.

There used to be a need for an empty smm_init() function
because initialize_cpus() called it even though nothing
called initialize_cpus(). However, garbage collection at
link time is implemented so there's no reason to provide an
empty function to satisfy a symbol that is completely culled
during link. Remove it.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

When CONFIG_CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM is set, this
function is now linked into the ramstage as well as the romstage,
since the former makes calls to it in panther builds.
With this commit, it's possible to build panther using the config file
from the Chromium OS project[1] if you supply the appropriate Intel
descriptor and ME binary blobs and manually set
CONFIG_VBOOT_VERIFY_FIRMWARE=n, CONFIG_BUILD_WITH_FAKE_IFD=n, and
CONFIG_HAVE_ME_BIN=y. The resulting image is at least able to load a
payload, although I only tested with depthcharge, which immediately
complained, "vboot handoff pointer is NULL" and gave up the ghost.

In some previous attempt to enable monotonic timers on all platforms,
the LAPIC monotonic timer was selected for Haswell devices, despite
the fact that LAPIC timers are not used in coreboot on Haswell

Now that we use the microcode updates in the blobs repository, remove
them from the main repo. Since the microcode updates are blobs, it
makes more sense to ship them in the blobs repo rather than the main
one.
The update-microcodes.sh script is also deleted, as a more current
version resides in 3rdparty.

Now that microcode has been added to blobs, use that one instead of
the one included in the tree. Microcode from the tree will be
removed in a subsequent patch. Since the microcode updates are blobs,
they belong in the blobs repository.
This change may introduce a build failure if the "Generate from tree"
microcode option is selected, but the blobs repository is not
enabled. We have to live with this for now, until microcode is moved
to blobs for all CPUs, at which point we may adjust Kconfig
accordingly.
Leave the FSP cpu alone for now, as that will need approval from
SAGE.

This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e
and fixes the build issue that cuased it to be reverted.
Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.
TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.

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.

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.

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.

This change allows Kconfig options ROM_SIZE and CBFS_SIZE to be
set with values that are not power of 2. The region programmed
as WB cacheable will include all of ROM_SIZE.
Side-effects to consider:
Memory region below flash may be tagged WRPROT cacheable. As an
example, with ROM_SIZE of 12 MB, CACHE_ROM_SIZE would be 16 MB.
Since this can overlap CAR, we add an explicit test and fail
on compile should this happen. To work around this problem, one
needs to use CACHE_ROM_SIZE_OVERRIDE in the mainboard Kconfig and
define a smaller region for WB cache.
With this change flash regions outside CBFS are also tagged WRPROT
cacheable. This covers IFD and ME and sections ChromeOS may use.

CPU_MICROCODE_IN_CBFS was designed to mean that loading microcode updates
from a CBFS file is supported, however, the name implies that microcode is
present in CBFS. This has recently caused confusion both with contributions
from Google, as well as SAGE. Rename this option to
SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is
"hey, the code we have for this CPU supports loading microcode updates from
CBFS", and prevent further confusion.

fix, pass the copy_spd function to romstage_common, to be called at the

When an INIT# is delivered to the CPU the CPU starts
executing from the reset vector. However, the internal state
is maintained. Therefore, check for such a condition and
reset the system.
Issues 'apreset warm' on the EC console. INIT# is sent and
CPU notices it's not a clean reset and forces one. No hangs.

On haswell ULT systems there is a 24MHz clock that continuously runs
when deep package c-states are entered. The 100MHz BCLK is shut down
in the lower c-states. When the package wakes back up a conversion
formula needs to be applied. The 24MHz calibration is done using the
internal PCODE unit.

The c-states are configured according to the BWG, however the
package c-states are disabled as they currently cause platform
instability. The exposed ACPI c-state to processor c-state mapping
are as follows for ULT boards:
ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C7S long latency)
ACPI(C3) = MWAIT(C10)
The non-ULT boards have an expoed c-state mapping:
ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C3)
ACPI(C3) = MWAIT(C7S)
Included in this patch is removing the updating of current limit
registers as some of the MSRs are different and the proper values
are currently unknown. Lastly, some of the MSRs were renamed to
match the BWG.
Booted 3.8 kernel and used powertop to note package, core, and acpi
c-state residency.

The recommendation from Intel is to report each core as a
separate logical domain in the _PSD table.
This goes against the recommendation in the ACPI specification
because all of these cores are on the same package and share a
VR so they will do voltage transitions together.
The reasoning is that with a larger number of logical processors
the P-state often ramps too quickly resulting in higher power
consumption. By exposing each core as a separate domain the OS
can manage them individually allowing the socket to select the
optimum frequency.

If romstage does not make cbmem_initialize() call, linker should
optimize the code for CAR migration away.
This simplifies design of CBMEM console by a considerable amount.
As console buffer is now migrated within cbmem_initialize() call there
is no longer need for cbmemc_reinit() call made at end of romstage.
