    ARM: 7692/1: iop3xx: move IOP3XX_PERIPHERAL_VIRT_BASE · f5d6a144
    Aaro Koskinen authored
    Currently IOP3XX_PERIPHERAL_VIRT_BASE conflicts with PCI_IO_VIRT_BASE:
    
    					address         size
    	PCI_IO_VIRT_BASE                0xfee00000      0x200000
    	IOP3XX_PERIPHERAL_VIRT_BASE     0xfeffe000      0x2000
    
    Fix by moving IOP3XX_PERIPHERAL_VIRT_BASE below PCI_IO_VIRT_BASE.
    
    The patch fixes the following kernel panic with 3.9-rc1 on iop3xx boards:
