Stefan Reinauer bf729baa2c Add more timestamps in coreboot.
This adds a number of timestamps in ramstage and romstage
so we can figure out where execution time goes.

Vadim Bendebury 10fea92477 Fix coreboot makefiles not to produce half baked output.
It looks like the cbfstool utility generates the output file even when
it fails to generate it properly. This causes make, if started second
time in a row, after cbfstool failure, to continue beyond the point of
failure (as the corrupted output file is present in the output tree,
the second make invocation presumes that it is valid, as it is newer
than the dependencies).

The output file should be created only when successful, in an atomic
operation. There could be other places in the make system which
require a similar fix, this needs to be investigated further.

Stefan Reinauer 3008bbadcb Add TPM support to coreboot
and initialize the TPM on S3 resume

This patch integrates the TPM driver and runs TPM resume upon an ACPI S3
resume without including any other parts of vboot.

We could link against vboot_fw.a but it is compiled with u-boot's CFLAGS
(that are incompatible with coreboot's) and it does a lot more than we
want it to do.

Gabe Black 19e7e7d2e7 Add infrastructure for global data in the CAR phase of boot
The cbmem console structure and car global data are put in their own section,
with the cbmem console coming after the global data. These areas are linked
to be where CAR is available and at the very bottom of the stack.

There is one shortcoming of this change:
The section created by this change needs to be stripped out by the Makefile
since leaving it in confuses cbfstool when it installs the stage in the image.
I would like to make the tools link those symbols at the right location but
leave allocation of that space out of the ELF.

This is a python script which is supposed to run on a target

memory looking for the CBMEM signature at addresses aligned at
128K boundary. Once the script finds the CBMEM, it iterates
through the CBMEM table of contents and parses two entries: the
timestamps and the console log.

This submission is just a template to build upon to create a
utility for displaying CBMEM information while running Linux on
the target.

Vadim Bendebury 32da8bed19 CBMEM CONSOLE: Add CBMEM console driver implementation.
The CBMEM console driver saves console output in a CBMEM area, which
then is made available to Linux applications for perusing.

There are some system limitations which need to be worked around
to achieve this goal:

- some console traffic is generated before DRAM is initialized,
  leave alone CBMEM initialized.

- after the RAM based stage starts, a lot of traffic is generated
  before CBMEM is initialized.

As a result, the console log lives in three different places -
the bottom of the cache as RAM space, the CBMEM buffer (where it
is expected to be) and a static buffer used early in the RAM
stage.

When execution starts (in the cache as RAM mode), the console
buffer is allocated at the bottom of the cache as RAM memory
address range. Once DRAM is initialized, the CBMEM structure is
initialized, and then the console buffer contents are copied from
the bottom of the cache as RAM space into the CBMEM area right
before the cache as RAM mode is disabled. The
src/lib/cbmem_console.c:cbmemc_reinit() takes care of the
copying.

At this point the cache as RAM memory is about to be disabled,
but the ROM stage is still going generating console output. To
make sure this output is not lost, cbmemc_reinit() saves the new
buffer address at a fixed location (0x600 was chosen for this),
and the actual "printing" function checks to see if the RAM is
already initialized (the stack is in RAM), and if so, gets the
console buffer pointer from this location instead of using the
cache as RAM address.

When the RAM stage starts, a static buffer is used to store the
console output, as the CBMEM buffer location is not known. Then,
when CBMEM is reinitialized, cbmemc_reinit() again takes care of
the copying.

In case the allocated buffers are not large enough, the excessive
data is dropped, and the copying routine adds some text to the
output buffer to indicate that there has been data lost and how
many characters were dropped.

Also, since the CBMEM area could already contain a section (from the

request we should check if a section already exists and return its

This change initializes the CBMEM while still in rom stage in

Note that there is a discrepancy in how coreboot determines the
size of DRAM at rom and ram stages, get_top_of_ram() is used at
rom stage and is not defined for all platforms. Those platforms
will have to define this function should they enable the

Kyösti Mälkki 8b28d50cdd Intel cpus: Fix deadlock on hyper-threading init
Only the BSP CPU was able to start its hyper-threading CPU siblings.
When an AP CPU attempts this it calls start_cpu() within start_cpu(),
deadlocking the system with start_cpu_lock.

At the time intel_sibling_init() is run, the BSP CPU is still
walking the cpu_bus linked list in lapic_cpu_init: start_other_cpus().
A sibling CPU appended at the end of this list will get started.

Also fail compile with #error if SERIAL_CPU_INIT==0, as microcode
updates on hyper-threading sibling CPUs must be serialized.

Tested with HT-enabled P4 Xeons on dual-socket604 platform.

Kyösti Mälkki e77b9a0ab7 Replace ramtest pattern to assist in DIMM configuration
This is developer's testtool. Output from a "rotate ones" -style
pattern helps figure out how DIMM addresses are encoded or routed
on a certain mainboard.

Scattered test should cover every data and address lines on the memory
bus, but is probably limited to the first bank of first DIMM.

power-off, replug device -> device turns on; and similar cases).

Patrick Georgi 5161509132 printf: Remove some L modifier uses
We use the L modifier in a non-standard way (for
long long instead of long double, which we have no
business with).
clang complains, to reduce its use, to make
emulation/qemu-x86 happier.
Long term, we should consider eliminating public uses
of 'L' (but internal use in vtxprintf to denote
long long is fine)

Marc Jones ccee6256b4 Fix libpayload alloc() size and gcc pointer optimization problems.
The previous commit was incomplete and missed setting the entire
alloc area.

There are also additional problems with gcc optimizations of the
pointer math. The "auto" casting by gcc wouldn't return warnings,
but it was causing the optimization to be incorrect. We are now
very explicit in the casting in the pointer math.

Patrick Georgi 06c04299c1 Another indirection for normal/fallback bootblock
Provide a way to redefine the names of normal and fallback via CBFS.
This way updates can use some more expressive naming scheme (numbers,
dates, version numbers) and replace the coreboot-stages file to
point to the new version (with the current version as new "old").

If coreboot-stages doesn't exist, the default behaviour remains to
use "normal" and "fallback".
