Width mismatches

[olofk]

I'm getting width mismatch warnings on the last warp_address assignments

    if (len == 4'b1)
        warp_address[AXI_ADDR_WIDTH-1:1+LOG_NR_BYTES] = unaligned_address[AXI_ADDR_WIDTH-1:1+LOG_NR_BYTES];
    else if (len == 4'b11)
        warp_address[AXI_ADDR_WIDTH-1:2+LOG_NR_BYTES] = unaligned_address[AXI_ADDR_WIDTH-1:2+LOG_NR_BYTES];
    else if (len == 4'b111)
        warp_address[AXI_ADDR_WIDTH-1:3+LOG_NR_BYTES] = unaligned_address[AXI_ADDR_WIDTH-3:2+LOG_NR_BYTES];
    else if (len == 4'b1111)
        warp_address[AXI_ADDR_WIDTH-1:4+LOG_NR_BYTES] = unaligned_address[AXI_ADDR_WIDTH-3:4+LOG_NR_BYTES];

I haven't dug into the code to figure out how it all works, but looking at the first ones that don't have warnings, I wonder if it should just be

    else if (len == 4'b111)
        warp_address[AXI_ADDR_WIDTH-1:3+LOG_NR_BYTES] = unaligned_address[AXI_ADDR_WIDTH-1:3+LOG_NR_BYTES];
    else if (len == 4'b1111)
        warp_address[AXI_ADDR_WIDTH-1:4+LOG_NR_BYTES] = unaligned_address[AXI_ADDR_WIDTH-1:4+LOG_NR_BYTES];
