Author: uwe Date: Thu Sep 23 20:16:46 2010 New Revision: 5828 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5828
Log: USB Debug Port related license header fixes (trivial).
- Add missing license headers, or missing (C) lines to various files. (most are from AMD / Yinghai Lu, based on svn logs)
- src/include/ehci.h was taken from the Linux kernel. Updating it to the latest version from git HEAD while I'm at it (build-tested with one board). It also sports some new EHCI 1.1 addendum #defines which we may or may not need.
This new file also already has a proper GPL header.
