The romcc bootblock will be deprecated soon and most platforms use
C_ENVIRONMENT_BOOTBLOCK already. This patch drops the
CONFIG_C_ENVIRONMENT_BOOTBLOCK symbol and adds CONFIG_ROMCC_BOOTBLOCK
where needed.

Due to the way CAR teardown is handled in FSP 1.0, the results of
car_get_var_ptr() aren't always reliable, which can break things when
running with FMAP cache. It might be possible to fix this but would make
the code rather complicated, so let's just disable the feature on these
platforms and hope they die out soon.
Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.
In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.
Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

As code already used CBMEM hooks to switch from CAR to CBMEM
it was never necessary to have the structure declared inside
_car_relocatable_data.
Switch to use car_[get|set]_ptr is mostly for consistency, but
should also enable use of usbdebug with FSP1.0 romstage.

Keep track of the active timestamp table location using
a CAR_GLOBAL variable. Done this way, the entire table
can be located outside _car_relocatable_data and we only
switch the pointer to CBMEM and copy the data before
CAR gets torn down.
Fix comments about requirements of timestamp_init() usage.
Remove timestamp_cache from postcar and ramstage, as CBMEM
is available early on.

The sandybridge systemagent-r6 blob is modified:
- To be more flexible about the location of the stack w.r.t. the heap
- Place the MRC pool right below the MRC_VAR region
- to work with the same DCACHE_RAM_BASE from the native raminit (could
make the CAR linker symbols easily compatible if desired)
This allows CAR setup compatibility between mrc.bin and native
bootpath and also allows for BIOS/memory mappeds region larger than
8MB.
This changes the semantics of CONFIG_DACHE_RAM_MRC_VAR_SIZE to also
include the pool on top of MRC_VAR region.
TESTED on T520 (boots and resumes from S3 with mrc.bin).

Previously, the size of memory made for vboot_working_data
through the macro VBOOT2_WORK was always specified in each
individual memlayout file. However, there is effectively no
reason to provide this customizability -- the workbuf size
required for verifying firmware has never been more than 12K.
(This could potentially increase in the future if key sizes
or algorithms are changed, but this could be applied globally
rather than for each individual platform.)
This CL binds the VBOOT2_WORK macro to directly use the
VB2_WORKBUF_RECOMMENDED_DATA_SIZE constant as defined by vboot
API. Since the constant needs to be used in a linker script, we
may not include the full vboot API, and must instead directly
include the vb2_constants.h header.

Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.
In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.
The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

Sometime preram cbmem logs are truncated due to lack of
space (default preram cbmem console size is 0xc00).
Provide Kconfig option to configure preram cbmem console
size so that mainboard can configure it to required value.

Attempt to better document the symbol usage in car.ld for
cache-as-ram usage. Additionally, add _car_region_[start|end]
that completely covers the entire cache-as-ram region. The
_car_data_[start|end] symbols were renamed to
_car_relocatable_data_[start|end] in the hopes of making it
clearer that objects within there move. Lastly, all these
symbols were added to arch/symbols.h.

This patch generalizes the approach previously used for ARM32
TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
memlayout.ld. This allows us to get rid of the explicit Kconfig for the
TIMESTAMP region, reducing configuration redundancy and avoiding
confusion when setting up future boards.
(Removing armv4/bootblock_simple.c because it references this Kconfig
and it is a dead file that I just forgot to remove in CL:12076.)

Some platforms may want to use C code in bootblock so they need
writable memory and CAR can be used for it. This change reserves
memory in CAR that can be used by bootblock and other CAR stages.

Instead of tagging object files with .<class>, move them to a <class>
directory below $(obj)/. This way we can keep a 1:1 mapping between
source- and object-file names.
The 1:1 mapping is a prerequisite for Ada, where the compiler refuses
any other object-file name.
Tested by verifying that the resulting coreboot.rom files didn't change
for all of Jenkins' abuild configurations.

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.

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.

In order to do a verification of romstage on x86 one needs to
run verstage which verifies romstage (and the memory init code).
However, x86 doesn't have SRAM like every other modern SoC so
managing the cache-as-ram region is especially critical.
First move all of the "shared" objects to the beginning of
the .car.data section. This change then ensures that each stage
using car.ld to link has the same consistent view of the addresses
of these fixed-sized objects in cache-as-ram. The CAR_GLOBALs can
be unique per stage. However, these variables are expected to have
a value of zero at the start of each stage. In order to allow a
stage to provide those semantics outside of the initial cache-as-arm
setup routine add _car_global_start and _car_global_end symbols.
Those symbols can be used to clear the CAR_GLOBALs for that stage.
Note that the timestamp region can't be moved out similarly to the
pre-ram cbmem console because the object storage of the timestamp
cache is used *after* cache-as-ram is torn down to indicate if the
cache should be used or not. Therefore, that timestamp needs to
migrated to ram. A logic change in src/lib/timestamp.c could
alleviate this requirement, but that task wasn't tackled in this
patch.

To reduce file clutter merge romstage.ld and ramstage.ld
into a single memlayout.ld. The naming is consistent with
other architectures and chipsets for their linker script
names. The cache-as-ram linking rules are put into a separate
file such that other rules can be applied for future verstage
support.
