New Revision: 198431
URL: http://svn.freebsd.org/changeset/base/198431
Log:
BIOSes, buggy or otherwise, are i386 or amd64 specific.
Have the early USB takeover enabled for i386 and amd64
by default.
This also avoids a panic on PowerPC where the resource
isn't released properly and we find a busy resource
when the USB host controller wants to allocate it...
