Subject: [PATCH] zr36120: implement pcipci checks
Date: Thu, 14 Sep 2006 13:55:40 +0100 [thread overview]
Message-ID: <1158238540.21860.34.camel@localhost.localdomain> (raw)
Again depends on the PCIAGP_FAIL patch for a define. Someone with more
card knowledge should look at the ALIMAGIK case and whether latency can
be safely to set to 0xA or so.
