[PATCH 33.0 1/5] LEON: updated AMBA PnP API

Gedare Bloom gedare at rtems.org
Sun Apr 15 18:34:50 UTC 2012


This is a big one! Most of this is specific to the leon bsps so I just
glanced it over. I have just two comments.

First you can eliminate the $Id$ tags.

Second is the indentation. We usually use 2 spaces per indent level
while this code uses 6 or so.
