Julius Werner 98eeb96135 commonlib: Add commonlib/bsd
This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.

Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).

Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.

Jacob Garber 4fbd22e38d util/intelvbttool: Add error checking for memory allocation
It is possible that 'malloc_fo_sub' and 'remalloc_fo' can
fail, so add appropriate error checks for those cases.
This incidentally fixes a possible memory leak when
'malloc_fo_sub' succeeds but 'remalloc_fo' does not.

Alex Feinman 2223cbf7de intelvbttool: Add support for reading vbt from sysfs
VBT on Intel(R) systems is available via sysfs as
    /sys/kernel/debug/dri/0/i915_vbt
However the size of this file reads as 0 causing
intelvbttool to fail. This patch implements incremental reads
with realloc for such cases or whenever the file size is not
available (e.g. reading from stdin).
After this patch is applied, intelvbttool can be used as follows:
    sudo intelvbttool -f /sys/kernel/debug/dri/0/i915_vbt -d

Patrick Rudolph aece006b38 util/intelvbttool: Cleanup and fixes
* Clear remalloced memory
* Fix check for invalid VBT offset in header
* Fix VBIOS checksum generation
* Fix VBIOS size field
* Align VBIOS size to multiple of 512
* Reassign pointers after use of remalloc
* Don't leak on error path

Current version is enough to allow the proprietary Windows Intel GMA
driver to find the VBT in the legacy VBIOS area and it doesn't BSOD
any more.

The LVDS screen remains black, due to an unknown issue with the
proprietary driver, while the VGA works.

Tested with libgfxinit and native graphics init.

Patrick Rudolph 17856b720b util/intelvbttool: Rewrite tool
* Add Makefile dependency to source file
* Add argument support
* Add help support
* Print usage on wrong arguments
* Add support for parsing VBT binary file
* Add support for parsing PCI Option ROM
* Add support for writing VBT binary file
* Add support for patching PCI Option ROM
* Keep support for accessing legacy VGA area Option ROM
* Keep support for dumping VBT contents to stdout

Allows to extract VBT, analyse VBT and patch PCI Option ROMs as needed.

The required arguments have been changed:

./intelvbttool --<SOURCECMD> [filename] --<DESTCMD> [filename]

SOURCECMD set the VBT source. Supported:
 inlegacy  : Legacy BIOS area at phys. memory 0xc0000
 invbt     : Read raw Intel VBT file
 inoprom   : Read VBT from Intel Option ROM file

DESTCMD set the VBT destination. Supported:
 outdump   : Print VBT in human readable form
 outvbt    : Write raw Intel VBT file
 patchoprom: Patch existing Intel Option ROM

Any combination of SOURCECMD and DESTCMD is possible.

Patrick Georgi a73b93157f tree: drop last paragraph of GPL copyright header
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.

Paul Menzel ccc2af14c1 intelvbttool: Add Makefile
Add minimal Makefile based on cbmem’s Makefile.

The make target `junit.xml` is removed as this is handled differently
since commit de9adebb (Add junit.xml code to top Makefile.inc instead of
utils).

Also the `junit.xml` is removed in the make target `clean`.

Additionally, the make target `distclean` is added, as the current
junit.xml code in the top `Makefile.inc` requires that.
