PCI_IOBASE is used to create VM maps for PCI I/O ports, it is required by generic PCI drivers to make memory mapped I/O range work. Hence define it for ralink architectures to be able to avoid parsing manually IO ranges in PCI generic driver code. Function 'plat_mem_setup' for ralink is using 'set_io_port_base' call using '0xa0000000' as address, so use the same address in the definition to align things.

Why this sudden switch to spaces for indentation? Previous lines were (correctly) indented with tabs...
