From 3d1f664ab940382e7faa597fdfefed4acb163afc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Fri, 1 Jan 2016 15:30:03 +0100 Subject: [PATCH] MIPS: BCM47xx: Support SPROM prefixes on other platforms MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit BCM47XX platform has specific PCI setup because all buses share the same domain. It's different e.g. on ARM ARCH_BCM_5301X where each PCI bus gets its own domain (they are handled by iProc PCIe controller driver). As we want to make SPROM driver more generic, let's add an exception for BCM47xx. It was tested on BCM4706 (MIPS) and BCM4708A0 (ARM).
