Subject: [PATCH 1/7] POWERPC cpm_uart: OF-related fix for CPM1
Date: Wed, 24 Jan 2007 22:40:49 +0300 [thread overview]
Message-ID: <20070124194049.3385.34442.stgit@localhost.localdomain> (raw)
In-Reply-To: <20070124193402.3385.79090.stgit@localhost.localdomain>
This makes cpm uart able to work using OF-passed parameters
in case of CPM stuff (found on most mpc8xx reference and custom
boards). The idea is to keep ppc stuff working yet making it able to be
used for powerpc.
