This is different from e.g. Atheros PB42 and Ubiquiti boards. * Check for hint hint.pcib.0.baseslot=X, where X is number of base slot; * If hint not supplied print a warning and use default AR71XX_PCI_BASE_SLOT; PR: kern/174978 Approved by: adrian (mentor) Modified: head/sys/mips/atheros/ar71xx_pci.c Modified: head/sys/mips/atheros/ar71xx_pci.c ============================================================================== --- head/sys/mips/atheros/ar71xx_pci.c Sun Jan 6 19:27:28 2013 (r245111) +++ head/sys/mips/atheros/ar71xx_pci.c Sun Jan 6 20:50:31 2013 (r245112) @@ -81,6 +81,7 @@ struct ar71xx_pci_softc { device_t sc_dev; int sc_busno; + int sc_baseslot; struct rman sc_mem_rman; struct rman sc_irq_rman; @@ -395,6 +396,16 @@ ar71xx_pci_attach(device_t dev) AR71XX_PCI_IRQ_END) != 0) panic("ar71xx_pci_attach: failed to set up IRQ rman"); + /* + * Check if there is a base slot hint.
