[coreboot] [commit] r5616 - in trunk/payloads/libpayload: drivers/usb include/usb
repository service
svn at coreboot.org
Mon Jun 7 15:58:18 CEST 2010
Author: oxygene
Date: Mon Jun 7 15:58:17 2010
New Revision: 5616
URL: https://tracker.coreboot.org/trac/coreboot/changeset/5616
Log:
Avoid using the name "pid_t", which is used on unixoid systems.
Move controller specific data structures into private headers,
to avoid conflicts between controller drivers.
Factor out the USB PID ids, which are only exposed on UHCI. It's
of not much use on the other controllers.
