    Originally, both sdram_start and sdram_end were 64b values. The
    sdram_start had no reason for being so, since our address space
    is only 32b, so switching sdram_start to u32 is simple.
    
    The sdram_end is a bit more complex, since it can actually be
    set to (1 << 32) if someone really wanted to use an SoCFPGA with
    4 GiB of DRAM and fixed the code around a little. But, the code
    handling the protection rules internally decrements the sdram_end
    variable anyway. Thus, instead of calling the code and passing in
    the address of the SDRAM end, pass in the address already decremented
    by one. This lets the sdram_end be 32b as well.
