MIF addressing is dependent upon the mode selected by bit 1 of address offset 0x1 detailed in the "Streamer Module Internal MIF Register Offsets" table of the PHY IP Userguide.
The MIF address bus of the reconfiguration controller is 16-bit aligned when word addressing is used. In this case the LSB is unused. When you use the reconfiguration controller in MIF streaming mode, you should connect the address bus to the ROM as shown in the example below:
reconf_rom rom0(
.clock(phy_mgmt_clk),
.address(reconfig_mif_address[9:1]),
.q(reconfig_mif_readdata));
