Fix a linking problem with VBOOT and USE_OPTION_TABLE enabled.
Make use of cbfs_locate_file_in_region() and always search the
cmos_layout.bin in the 'COREBOOT' region.
With this change applied there's no need to include the vboot_locator
in SMM any more, we can't break NVRAM with different CMOS layouts,
and we keep VBOOT and non VBOOT behaviour the same.
Only include cmos_layout.bin and cmos.default in RO region.
Add notes explaining the decisions.
Tested on Intel Sandybridge, builds and boots with vboot enabled.

Masked ROMs are the silent killers of boot speed on devices without
memory-mapped SPI flash. They often contain awfully slow SPI drivers
(presumably bit-banged) that take hundreds of milliseconds to load our
bootblock, and every extra kilobyte of bootblock size has a hugely
disproportionate impact on boot speed. The coreboot timestamps can never
show that component, but it impacts our users all the same.
This patch tries to alleviate that issue a bit by allowing us to
compress the bootblock with LZ4, which can cut its size down to nearly
half. Of course, masked ROMs usually don't come with decompression
algorithms built in, so we need to introduce a little decompression stub
that can decompress the rest of the bootblock. This is done by creating
a new "decompressor" stage which runs before the bootblock, but includes
the compressed bootblock code in its data section. It needs to be as
small as possible to get a real benefit from this approach, which means
no device drivers, no console output, no exception handling, etc.
Besides the decompression algorithm itself we only include the timer
driver so that we can measure the boot speed impact of decompression. On
ARM and ARM64 systems, we also need to give SoC code a chance to
initialize the MMU, since running decompression without MMU is
prohibitively slow on these architectures.
This feature is implemented for ARM and ARM64 architectures for now,
although most of it is architecture-independent and it should be
relatively simple to port to other platforms where a masked ROM loads
the bootblock into SRAM. It is also supposed to be a clean starting
point from which later optimizations can hopefully cut down the
decompression stub size (currently ~4K on RK3399) a bit more.
NOTE: Bootblock compression is not for everyone. Possible side effects
include trying to run LZ4 on CPUs that come out of reset extremely
underclocked or enabling this too early in SoC bring-up and getting
frustrated trying to find issues in an undebuggable environment. Ask
your SoC vendor if bootblock compression is right for you.

It turns out that even with the `-gnatp` switch to suppress runtime
checks, the compiler is still allowed to generate them (it only doesn't
have to). If we can't control generation of checks, we also can't
make assumptions about propagation of their exceptions.
The compiler warning that led to this change seems spurious, though
(the check might be generated, but is dropped later). So we might
revert this decision if the compiler can be fixed.

The patch series ending in 64049be (lib/bootmem: Add method to walk OS
POV memory tables) expanded the bootmem framework to also keep track of
memory regions that are only relevant while coreboot is still executing,
such as the ramstage code and data. Mixing this into the exsting bootmem
ranges has already caused an issue on CONFIG_RELOCATEABLE_RAMSTAGE
boards, because the ramstage code in CBMEM is marked as BM_RAMSTAGE
which ends up getting translated back to LB_RAM in the OS tables. This
was fixed in 1ecec5f (lib/bootmem: ensure ramstage memory isn't given to
OS) for this specific case, but unfortunately Arm boards can have a
similar problem where their stack space is sometimes located in an SRAM
region that should not be made available as RAM to the OS.
Since both the resources made available to the OS and the regions
reserved for coreboot can be different for each platform, we should find
a generic solution to this rather than trying to deal with each issue
individually. This patch solves the problem by keeping the OS point of
view and the coreboot-specific ranges separate from the start, rather
than cloning it out later. Ranges only relevant to the coreboot view
will never touch the OS-specific layout, to avoid the problem of losing
information about the original memory type of the underlying region that
needs to be restored for the OS view. This both supersedes the
RELOCATABLE_RAMSTAGE fix and resolves the problems on Arm boards.

* Mark memory allocated by bootmem as BM_TAG_PAYLOAD.
* Assert on failures.
* Add _stack and _program as BM_MEM_RAMSTAGE.

On many recent Chrome OS boards, the desire to unite more configurations
under the same image has led to the need of a "SKU ID" that identifies
different configurations of the same board (e.g. with certain optional
components stuffed or not stuffed, or replaced with a comparable
component). This is markedly different from the existing "board ID",
because that is reserved to count "revisions" -- changes made to the
same configuration over time during the development process. This patch
adds support to have a mainboard define this SKU ID and pass it through
the coreboot table like we already have for board IDs.

This patch switches the board_id and ram_code helper framework to use
weak functions rather than Kconfigs to determine whether the board
supplies these IDs. This cuts down on the amount of boilerplate Kconfigs
many boards have to set and also gives them more flexibility, such as
being able to determine at runtime whether a given ID is present.

Merge the different coreboot table strapping ID structures into one
because they're really just all the same, and I want to add more. Make
the signature of the board_id() function return a uint32_t because
that's also what goes in the coreboot table. Add a printk to the generic
code handling strapping IDs in ramstage so that not every individual
mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)

The BOARD_ID_MANUAL and BOARD_ID_STRING options were introduced for the
Urara board which is now long dead, and have never been used anywhere
else. They were trying to do something that we usually handle with a
separate SKU ID these days, whereas BOARD_ID is supposed to be reserved
for different revisions of the same board/SKU. Get rid of it to make
further refactoring of other options easier.
Also shove some stuff back into the Urara mainboard that should've never
crept into generic headers.

Add a function to retrieve the elapsed time since boot. For that purpose
use the base time in the timestamp table among with the current
timestamp at call time of the function. So more precise the returned
time is the elapsed time since the timestamp was initialized scaled
in microseconds. This was chosen to get a reliable value even on
platforms where the TSC might not be reset on software reset or warm

Zero the framebuffer structure so if it is not filled in (either if
no display is present or if there is an error) then it does not
provide garbage data to the payload.
This was noticed when booting a board without a display attached as
the payload wrote to the framebuffer at a random address.
With this change the payload can properly handle the case where a
display is not attached and not corrupt memory.

The vboot code tries reading rollback protection indices from the TPM,
and if the attempt to read returns TPM_E_BADINDEX, it decides that the
TPM has not yet been initialized for the Chromebook use, and needs to
be taken through the factory initialization sequence.
TPM_E_BADINDEX is an internal representation of the TPM error 0x28b,
generated on attempts to read a non existing NVMEM space.
If the space exists, but has never been written the TPM returns error
0x14a. This condition (the space exists but not written) could happen
if the previous factory initialization attempt was interrupted right
after the space was created.
Let's map this error to the same internal representation
(TPM_E_BADINDEX) so that the Chrome OS device could recover when this
condition occurs.
BRANCH=reef, gru

There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.
This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).
Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

The 'cbmem -1' flag that cuts off console output before the last boot
will ignore content from earlier stages if it was truncated due to lack
of pre-CBMEM console space. This patch makes the "log truncated" message
more specific and adds it as an additional cut-off marker to 'cbmem -1'
to counteract that problem.
Also raise the log level of the coreboot banner one step to BIOS_NOTICE
to make it more likely to be included in the output for 'cbmem -1' to
find. (I believe NOTICE is reasonable but I wouldn't want to go as far
as WARN which should be reserved for actual problems. Of course this is
not ideal, but then again, our whole log-level system really isn't... it
would be better if we could make it always print a banner to the CBMEM
console without affecting the UART at the same time, but that would
require a larger amount of work.)

For some reason the "interface" for adding framebuffer information
is sitting in src/include/vbe.h while also guarding the call to
fill_lb_framebuffer() with vbe_mode_info_valid() along with some
macro if CONFIG_* for good measure.
Move the fill_lb_framebuffer() declaration to coreboot_tables.h and
provide a comment about how it should be used. Also, now that
there's no need for the notion of a global vbe_mode_info_valid()
remove it from the conditional call path of fill_lb_framebuffer().

It turns out that there are quite a few other projects that can access
the CBMEM console by now. If we ever want to make another structural or
behavioral change to it, we need to know where these implementations are
so we can make sure they're all getting updated. Let's try to build a
comprehensive list in the file that should be the source of truth for
all (coreboot's own implementation).

This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)
The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).
