6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

The exceptions are for:

f3f36faf35 src (minus soc and mainboard): Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

75b1f768d8 cbmem: rename vdat to chromeos_acpi
There is a confusingly named section in cbmem called vdat.
This section holds a data structure called chromeos_acpi_t,
which exposes some system information to the Chrome OS
userland utility crossystem.

Within the chromeos_acpi_t structure, there is a member
called vdat.  This (currently) holds a VbSharedDataHeader.

Rename the outer vdat to chromeos_acpi to make its purpose
clear, and prevent the bizarreness of being able to access
vdat->vdat.

Additionally, disallow external references to the
chromeos_acpi data structure in gnvs.c.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

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
we may want to synchronize every now and then.

06ece7de93 chromeos: provide option to dynamically allocate ram oops buffer
Fixing the location of the ram oops buffer can lead to certain
kernel and boot loaders being confused when there is a ram
reservation low in the address space. Alternatively provide
a mechanism to allocate the ram oops buffer in cbmem. As cbmem
is usually high in the address space it avoids low reservation
confusion.

The patch uncondtionally provides a GOOG9999 ACPI device with
a single memory resource describing the memory region used for
the ramoops region.

BUG=None

642b1db733 Eliminate use of pointers in coreboot table
Because pointers can be 32bit or 64bit big,
using them in the coreboot table requires the
OS and the firmware to operate in the same mode
which is not always the case. Hence, use 64bit
for all pointers stored in the coreboot table.
Guess we'll have to fix this up once we port to

1. vboot_loader.c - this file contains the entry point,
   vboot_verify_firmware(), for romstage to call in order to perform
   vboot selection. The loader sets up all the data for the wrapper
   to use.
2. vboot_wrapper.c - this file contains the implementation calling the vboot
   API. It calls VbInit() and VbSelectFirmware() with the data supplied
   by the loader.

The vboot wrapper is compiled and linked as an rmodule and placed in
cbfs as 'fallback/vboot'. It's loaded into memory and relocated just
like the way ramstage would be. After being loaded the loader calls into
wrapper. When the wrapper sees that a given piece of firmware has been
selected it parses firmware component information for a predetermined
number of components.

Vboot result information is passed to downstream users by way of the
vboot_handoff structure. This structure lives in cbmem and contains
the shared data, selected firmware, VbInitParams, and parsed firwmare
components.

During ramstage there are only 2 changes:

1. Copy the shared vboot data from vboot_handoff to the chromeos acpi
   table.
2. If a firmware selection was made in romstage the boot loader
   component is used for the payload.

Noteable Information:
- no vboot path for S3.
- assumes that all RW firmware contains a book keeping header for the
  components that comprise the signed firmware area.
- As sanity check there is a limit to the number of firmware components
  contained in a signed firmware area. That's so that an errant value
  doesn't cause the size calculation to erroneously read memory it
  shouldn't.
- RO normal path isn't supported. It's assumed that firmware will always
  load the verified RW on all boots but recovery.
- If vboot requests memory to be cleared it is assumed that the boot
  loader will take care of that by looking at the out flags in
VbInitParams.

Built and booted. Noted firmware select worked on an image with
RW firmware support. Also checked that recovery mode worked as well
by choosing the RO path.

8de884424c ELOG: Fix reporting of developer/recovery modes
Recent changes in EC/Vboot/U-boot have completely broken
the logging of developer and recovery modes.

Recovery mode may not be in VBNV, so if that is zero and
yet we are in recovery mode then assume it is there because
the button/key was pressed.

Since there may not be any actual developer mode switch
we look if option rom is loaded and the system is not
in recovery mode and consider that as developer mode.

27e5aacc52 ELOG: Log events for Chrome OS developer/recovery mode
If a Chrome OS device is in developer mode log an event.
When the device is in recovery mode also log an event
and provide the recovery reason.

Enable developer mode and trigger recovery mode and
verify that the events are logged:

238 | 2012-06-23 17:31:56 | Chrome OS Developer Mode
239 | 2012-06-23 17:31:56 | Chrome OS Recovery Mode | User Requested from Developer Screen

be1ef2329e chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared Data
coreboot used to pass some information to u-boot in the coreboot table
and other information in a modified flat device tree. Since the FDT code
was never upstreamed and removed from our tree, u-boot was changed to
get the information it needs from the coreboot table alone. However,
in the process of this change only the vboot shared data structure was
passed on by coreboot, so when u-boot tried to update the ChromeOS
specific ACPI entries, it would accidently overwrite the vboot data.
This patch passes on the ChromeOS specific ACPI data structure instead
of the vboot shared data. Another change to u-boot will teach it how
to get to the vboot shared data from there.

984f9540c0 ChromeOS: Remove remnants of FDT support
Originally, on ChromeBooks, coreboot would provide a modified
u-boot device tree (FDT) to u-boot in CBMEM. However, u-boot
can now create all the information it needs from the coreboot
table and add it to its device tree itself. This means we can
drop this (anyways unused) code.
