2018-11-12util/intelvbttool: Cleanup and fixesPatrick Rudolph
* 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.

2018-10-08util/intelvbttool: Rewrite toolPatrick Rudolph
* 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.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
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.
