[PATCH] MIPS: Octeon: Add PCIe2 support in arch_setup_msi_irq()

From: Eunbong Song
Date: Fri Apr 11 2014 - 04:33:17 EST



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.
