The existing mips_io_port_base variable isn't suitable for use early during boot since it will be stored in the .data section which may not be writable pre-relocation. Fix this by moving the I/O port base address into struct arch_global_data. In order to avoid adding this field for all targets, make this dependant upon a new Kconfig entry CONFIG_DYNAMIC_IO_PORT_BASE. Malta is the only board which sets a non-zero I/O port base, so select this option only for Malta. Signed-off-by: NPaul Burton <paul.burton@imgtec.com>
