The delay_tsc.c compilation unit used the C preprocessor
to conditionally compile different code paths. Instead of
guarding large blocks of code allow the compiler to optimize
out unreachable code.

The delay_tsc.c code took different paths depending
__PRE_RAM__ being defined or not. Also, timer_monotonic_get()
was only compiled in a !__PRE_RAM__ environment. Clean up
the code paths by employing CAR_GLOBAL for the global state
which allows the same code to be used in all stages.
Lastly, handle apollolake fallout now that init_timer() is
not needed in placeholders.c.

The current code in delay_tsc.c uses globals and is heavily
guarded by a lot of preprocessor macros. In order to remove
__PRE_RAM__ constraints one needs to use CAR_GLOBAL for the
global variables. Therefore, abstract away direct access to
the globals such that CAR_GLOBAL can be easily employed.

Certain chipsets don't have a memory-mapped boot media
so their code execution for stages prior to DRAM initialization
is backed by SRAM or cache-as-ram. The postcar stage/phase
handles the cache-as-ram situation where in order to tear down
cache-as-ram one needs to be executing out of a backing
store that isn't transient. By current definition, cache-as-ram
is volatile and tearing it down leads to its contents disappearing.
Therefore provide a shim layer, postcar, that's loaded into
memory and executed which does 2 things:
1. Tears down cache-as-ram with a chipset helper function.
2. Loads and runs ramstage.
Because those 2 things are executed out of ram there's no issue
of the code's backing store while executing the code that
tears down cache-as-ram. The current implementation makes no
assumption regarding cacheability of the DRAM itself. If the
chipset code wishes to cache DRAM for loading of the postcar
stage/phase then it's also up to the chipset to handle any
coherency issues pertaining to cache-as-ram destruction.

We currently race in SMM init on Atom 230 (and potentially
other CPUs). At least on the 230, this leads to a hang on
RSM, likely because both hyperthreads mess around with
SMBASE and other SMM state variables in parallel without
coordination. The same behaviour occurs with Atom D5xx.
Change it so first APs are spun up and sent to sleep, then
BSP initializes SMM, then every CPU, one after another.
Only do this when SERIALIZE_SMM_INITIALIZATION is set.
Set the flag for Atom CPUs.

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.

This mitigates the Memory Sinkhole issue (described on
https://github.com/xoreaxeaxeax/sinkhole) by checking for the issue and
crashing the system explicitly if LAPIC overlaps ASEG.
This needs to happen without a data access (only code fetches) because
data accesses could be tampered with.
Don't try to recover because, if somebody tried to do shenanigans like
these, we have to expect more.
Sandybridge is safe because it does the same test in hardware, and
crashes. Newer chipsets presumably do the same.
This needs to be extended to deal with overlapping TSEG as well.

To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

The x86 bootblock linking is a mess. The bootblock is treated in
a very special manner, and never received the update to link-time
garbage collection.
On newer x86 platforms, the boot media is no longer memory-mapped.
That means we need to do a lot more setup in the bootblock. ROMCC is
unsuitable for this task, and walkcbfs only works on memory-mapped
CBFS. We need to revise the x86 bootflow for this new case.
The approach this patch series takes is to perform CAR setup in the
bootblock, and load the following stage (either romstage or verstage)
from the boot media. This approach is not new, but has been done on
our ARM ports for years.
Since we will be adding .c files to the bootblock, it is prudent to
use link-time garbage collection. This is also consistent to how we
do things on other architectures. Unification FTW!

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

This reverts commit a3aa8da2acec28670b724b7897ae054592746674.
Chrome OS builds require the monotonic timer API in SMM for ELOG_GSMI,
but sandy/ivy doesn't provide it. The commit tried to work around that
by using generic LAPIC code instead, but this leads to multiple
definition errors in other configurations (and it may be unreliable once
the OS reconfigured the APIC timers anyhow).
This fixes the situation for the non-ELOG_GSMI case (which is more or
less everybody but Chrome OS). ELOG_GSMI requires a separate fix.

it will go back down the printk() path deadlocking oneself.

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.

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

Intermediate linking may distort linker behavior (in particular related to
weak symbols). The idea is that archives are closer to 'just a list of
object files', and ideally makes the linker more predictable.
Using --whole-archive, the linker doesn't optimize out object files just
because their symbols were already provided by weak versions. However it
shouldn't be used for libgcc, because that one has some unexpected side-effects.

This patch creates a new mechanism to define the static memory layout
(primarily in SRAM) for a given board, superseding the brittle mass of
Kconfigs that we were using before. The core part is a memlayout.ld file
in the mainboard directory (although boards are expected to just include
the SoC default in most cases), which is the primary linker script for
all stages (though not rmodules for now). It uses preprocessor macros
from <memlayout.h> to form a different valid linker script for all
stages while looking like a declarative, boilerplate-free map of memory
addresses to the programmer. Linker asserts will automatically guarantee
that the defined regions cannot overlap. Stages are defined with a
maximum size that will be enforced by the linker. The file serves to
both define and document the memory layout, so that the documentation
cannot go missing or out of date.
The mechanism is implemented for all boards in the ARM, ARM64 and MIPS
architectures, and should be extended onto all systems using SRAM in the
future. The CAR/XIP environment on x86 has very different requirements
and the layout is generally not as static, so it will stay like it is
and be unaffected by this patch (save for aligning some symbol names for
consistency and sharing the new common ramstage linker script include).

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.

BOOT_MEDIA_SPI_BUS is a Kconfig variable used on some ARM-based
platforms to set up CBFS media. It turns out it can also be helpful
for setting up the eventlog which is intended to reside on the same
SPI flash as CBFS. Setting it for x86 will allow us to remove an
assumption about which SPI bus is used for this flash device.
Long term this can go away as we come up with a better abstraction
for the eventlog's backing store. This is only intended to help us
get from here to there.

The code in src/cpu/x86/mtrr/mtrr.c disables caching in a few places when
changing mtrr settings. While I can't find anything that says that's actually
required, I can believe it's necessary. With that said, other code around the
wrmsr instructions which actually modify the settings should be able to run
with caching enabled with no ill effects.
This is particularly true for two calls to printk, one in the fixed mtrr code
and one in the variable, which could result in an arbitrary amount of work
being done without caching. When changing the implementation of the cbmem
console, these two printks caused a significant regression in boot performance
on link of about 70ms which is about 10% of total firmware boot time. When the
window where the cache is disabled is minimized, both this and the new
implementation were about 30ms faster than the original boot time.
For the variable MTRRs, we now store what we want to set the MSRs to and then
write them all at once at the end of commit_var_mtrrs(). This way we don't
have some set and some not, but we still minimize the time we spend with the
caches disabled.

This is essentially a revert of commit 10bd772d. The CAR_MIGRATE
mechanism is only useful to migrate variables from a special region
(e.g. cache as RAM) into DRAM-backed CBMEM between different parts of
the romstage (it does not persist into ramstage). Since ARM devices use
SRAM for which there is no reason to become inaccessible in later parts
of the romstage, this mechanism isn't useful for them. Removing it makes
the romstage.ld script much simpler, which has the nice side-effect of
putting the BSS at the end of the memory image (so that cbfstool can
actually figure out that it doesn't need to be part of the ROM image).
