FSP 1.0 has a fixed-size temporary cache size and address and the entire
cache is migrated in the FSP FspInitEntry() function.
Previous code expected the symbol _car_data_start to be the same as
CONFIG_DCACHE_RAM_BASE and _car_data_end to be the same as
_preram_cbmem_console.
FSP 1.0 is the only one that migrates _preram_cbmem_console.
Others leave that where it is and extract the early console data in
cbmemc_reinit(). Special handling is needed to handle that.
Commit dd6fa93d broke both assumptions and so broke the timestamp table
and console.
The fix is to use CONFIG_DCACHE_RAM_BASE when calculating the offset and
to use _preram_cbmem_console instead of _car_data_end for the console
check.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

The sysinfo object within the k8 ram init is used
to communicate progess/status from all the nodes in the
system. However, the code was assuming where the sysinfo
object lived in cache-as-ram. The layout of cache-as-ram
is dynamic so one needs to do the lookup of the correct
address at runtime. The way the amd code is compiled
by #include'ing .c files makes the solution a little
more complex in that some cache-as-ram support code
needed to be refactored.

Squashed and adjusted two changes from chromium.git. Covers
CBMEM init for ROMTAGE and RAMSTAGE.
cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API
There are several use cases for performing a certain task when CBMEM is
first set up (usually to migrate some data into it that was previously
kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them
differently: timestamp migration is called explicitly from
cbmem_initialize(), certain x86-chipset-specific tasks use the
CAR_MIGRATION() macro to register a hook, and the CBMEM console is
migrated through a direct call from romstage (on non-x86 and SandyBridge
boards).
This patch decouples the CAR_MIGRATION() hook mechanism from
cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer
description of what it really does. All of the above use cases are
ported to this new, consistent model, allowing us to have one less line
of boilerplate in non-CAR romstages.
BRANCH=None
BUG=None
TEST=Built and booted on Nyan_Blaze and Falco with and without
CONFIG_CBMEM_CONSOLE. Confirmed that 'cbmem -c' shows the full log after
boot (and the resume log after S3 resume on Falco). Compiled for Parrot,
Stout and Lumpy.

cbmem: Extend hooks to ramstage, fix timestamp synching
Commit 7dd5bbd71 (cbmem: Unify random on-CBMEM-init tasks under common
CBMEM_INIT_HOOK() API) inadvertently broke ramstage timestamps since
timestamp_sync() was no longer called there. Oops.
This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism
to the cbmem_initialize() call in ramstage. The macro is split into
explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as
possible and prevent surprises (although just using a single macro and
relying on the Makefiles to link an object into all appropriate stages
would also work).
This allows us to get rid of the explicit cbmemc_reinit() in ramstage
(which I somehow accounted for in the last patch without realizing that
timestamps work exactly the same way...), and replace the older and less
flexible cbmem_arch_init() mechanism.
Also added a size assertion for the pre-RAM CBMEM console to memlayout
that could prevent a very unlikely buffer overflow I just noticed.
BRANCH=None
BUG=None
TEST=Booted on Pinky and Falco, confirmed that ramstage timestamps once
again show up. Compile-tested for Rambi and Samus.

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.

This was added to handle cases of Intel FSP platforms that had
EARLY_CBMEM_INIT but could not migrate CAR variables to CBMEM.
These boards were recently fixed.
To support combination of EARLY_CBMEM_INIT without CAR migration was
added maintenance effort with little benefits. You had no CBMEM
console for romstage and the few timestamps you could store were
circulated via PCI scratchpads or CMOS nvram.

1) Save the pointer to the FSP HOB list to low memory at address 0x614.
This is the same location as CBMEM_RESUME_BACKUP - the two aren't used
in the same platform, so overlapping should be OK. I didn't see any
documentation that actually said that this location was free to use, and
didn't need to be restored after use in S3 resume, but it looks like
the DOS boot vector gets loaded juat above this location, so it SHOULD
be ok. The alternative is to copy the memory out and store it in cbmem
until we're ready to restore it.
2) When a request for the pointer to a CAR variable comes in, pass back
the location inside the FSP hob structure.
3) Skip the memcopy of the CAR Data. The CAR variables do not
get transitioned back into cbmem, but used out of the HOB structure.
4) Remove the BROKEN_CAR_MIGRATE Kconfig option from the FSP platform.

Always build CBMEM for romstage, even for boards that will not use it.
We further restrict car_migrate_variables() runs to non-ROMCC boards without
BROKEN_CAR_MIGRATE.
This fixes regression of commit 71b21455 that broke CBMEM console support
for boards with a combination of !EARLY_CBMEM_INIT && !HAVE_ACPI_RESUME.

There are some fun rules C compilers can use to optimize their code.
One of them is the assumption that two symbols point to two different

In this case this wasn't true, resulting in unintended code execution

There are some boards that do a significant amount of
work after cache-as-ram is torn down but before ramstage
is loaded. For example, using vboot to verify the ramstage
is one such operation. However, there are pieces of code
that are executed that reference global variables that
are linked in the cache-as-ram region. If those variables
are referenced after cache-as-ram is torn down then the
values observed will most likely be incorrect.
Therefore provide a Kconfig option to select cache-as-ram
migration to memory using cbmem. This option is named
CAR_MIGRATION. When enabled, the address of cache-as-ram
variables may be obtained dynamically. Additionally,
when cache-as-ram migration occurs the cache-as-ram
data region for global variables is copied into cbmem.
There are also automatic callbacks for other modules
to perform their own migration, if necessary.
