From mboxrd@z Thu Jan 1 00:00:00 1970 From: thomas.petazzoni@free-electrons.com (Thomas Petazzoni) Date: Wed, 6 Mar 2013 17:59:58 +0100 Subject: [PATCH 03/10] arm: mach-orion5x: use mv_mbus_dram_info() in PCI code In-Reply-To: <1362589205-4726-1-git-send-email-thomas.petazzoni@free-electrons.com> References: <1362589205-4726-1-git-send-email-thomas.petazzoni@free-electrons.com> Message-ID: <1362589205-4726-4-git-send-email-thomas.petazzoni@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The PCI code was directly accessing the orion_mbus_dram_info structure to get access to a description of the SDRAM chip selects in order to configure the PCIe -> SDRAM address decoding windows. However, with the introduction of the mvebu-mbus driver, we are going to remove this global structure and instead leave only the exported mv_mbus_dram_info() function to access this description of the SDRAM chip selects. Therefore, we simply switch to using this API.
