There are efforts to have bootflows that do not follow a traditional
bootblock-romstage-postcar-ramstage model. As part of that CBMEM
initialisation hooks will need to move from romstage to bootblock.
The interface towards platforms and drivers will change to use one of
CBMEM_CREATION_HOOK() or CBMEM_READY_HOOK(). Former will only be called
in the first stage with CBMEM available.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

It seems that GCC's LTO doesn't like the way we implement
DECLARE_OPTIONAL_REGION(). This patch changes it so that rather than
having a normal DECLARE_REGION() in <symbols.h> and then an extra
DECLARE_OPTIONAL_REGION() in the C file using it, you just say
DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead
of the usual DECLARE_REGION()). This basically looks the same way in the
resulting object file but somehow LTO seems to like it better.

With CB:32726 ("lib/timestamp: Make timestamp_sync_cache_to_cbmem() in
postcar") timestamps are synced from cache to cbmem in postcar as
well. For postcar, the cache lives in BSS just like ramstage. This
change updates TIMESTAMP_CACHE_IN_BSS to include both ramstage and
postcar and uses this instead of ENV_RAMSTAGE to check for cache
location.
Ideally, it would be good to get rid of timestamp cache in postcar and
ramstage completely since early cbmem init is enabled by default in
coreboot and it is guaranteed that cbmem is recovered before
timestamps are added in ramstage or postcar. This change is being
pushed in as a temporary fix while I make the changes to remove
timestamp cache from romstage and postcar completely.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

timestamp_cache_get() would call timestamp_cache_init() whenever it
found a timestamp cache in the TIMESTAMP_CACHE_UNINITIALIZED state.
That means that timestamp_cache_get() will never reurn a cache in the
uninitialized state.
However, timestamp_init() checks against the uninitialized state, as
it does not expect timestamp_cache_get() to perform any initialization.
As a result, the conditional branch can never be reached.
Simply remove the timestamp_cache_init() call from timestamp_cache_get().

If the timestamp table gets corrupted (separate issue), the
timestamp_sync_cache_to_cbmem() function may add a large number of bogus
timestamp entries.
This causes a flood of "ERROR: Timestamp table full". With logs going
to a serial console, this renders the system essentially unbootable.
There really isn't a need to log that more than once, so log it when the
last slot in the timestamp table is filled.

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

Add the timestamp tick frequency within the timestamp table so
the cbmem utility doesn't try to figure it out on its own. Those
paths still exist for x86 systems which don't provide tsc_freq_mhz().
All other non-x86 systems use the monotonic timer which has a 1us
granularity or 1MHz.
One of the main reasons is that Linux is reporting
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq as the true
turbo frequency on turbo enables machines. This change also fixes
the p-state values honored in cpufreq for turbo machines in that
turbo p-pstates were reported as 100MHz greater than nominal.

Commit bd1499d3 fixed a bug to not re-initialize the timestamp
cache in ramstage for EARLY_CBMEM_INIT. However, EARLY_CBMEM_INIT
was not included. Therefore, add this condition. This will result
in base_time being initialized to the passed in timestamp
for !EARLY_CBMEM_INIT platforms.

While running ramstage with the EARLY_CBMEM_INIT config the timestamp
cache was re-initialized and subsequently used. The result was that
the ramstage timestamps would be dropped from cbmem. The reason
is that the ramstage timestamps perpetually lived in ramstage BSS
never getting sync'd back into cbmem. The fix is to honor the
cache state in ramstage in the timestamp_init() path.
Also, make cache_state a fixed bit width to allow for different
architectures across the pre-ramstage stages.
TEST=Used qemu-armv7 as a test harness with debugging info.

In order to accommodate tracking timestamps in all the
__PRE_RAM__ stages (bootblock, verstage, romstage, etc)
of a platform one needs to provide a way to specify
a persistent region of SRAM or cache-as-ram to store
the timestamps until cbmem comes online. Provide that
infrastructure.

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.

With LATE_CBMEM_INIT, do not search for the initial collection from
CBMEM in ramstage. On S3 resume this would find the non-empty
collection from previous run of ramstage. Start with an empty table
instead.
Remove a spurious error message as the stamps get stashed and
will be copied to CBMEM later.
