From d19648d7f3b047bac9922fe097f62afbb48fee62 Mon Sep 17 00:00:00 2001 From: Eunbong Song Date: Fri, 11 Apr 2014 08:32:54 +0000 Subject: [PATCH] MIPS: Octeon: Add PCIe2 support in arch_setup_msi_irq() In arch_setup_msi_irq(), there is no case for PCIe2. So board which have PCIe2 functionality fails to boot with "Kernel panic - not syncing: arch_setup_msi_irq: Invalid octeon_dma_bar_type" message. This patch solve this problem.
