[coreboot] [commit] r5828 - in trunk/src: console include lib

repository service svn at coreboot.org
Thu Sep 23 20:16:46 CEST 2010


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.
