From 052345aec01cbd22285771eee6e08486c07d3bcc Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 26 Apr 2010 21:46:07 +0200 Subject: [ARM] pxa/vpac270: add ide support This patch adds support for the on-board IDE channel. I tested this with a CDROM connected over 2.5-3.5 IDE reduction with external power supplied to the CDROM. This was not tested with the Voipac 270-HDD-000 (official Voipac HDD module), but I expect no problems.
