From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Tue, 19 Feb 2008 12:34:46 +0000 Subject: [PATCH 03/09] sh: avoid using PCIBIOS_MIN_xxx Message-Id: <20080219123446.4266.65644.sendpatchset@clockwork.opensource.se> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org Replaces PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM with direct struct pci_channel access. This allows us to have more than one pci channel.
