As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

This option will have ELOG store a copy of the flash event log
|
|
in a CBMEM region and export that address in SMBIOS to the OS.
|
|
This is useful if the ELOG location is not in memory mapped flash,
|
|
but it means that events added at runtime via the SMI handler
|
|
will not be reflected in the CBMEM copy of the log.
