    Move constants to ROM. Frees up 16k+ of RAM. · b0f9788a
    Johny Mattsson authored
    Accessing 8bit and 16bit constants from ROM rather than RAM comes with a
    performance cost, as these loads go through the load/store exception
    vector. Any performance critical constants can be forced back into RAM
    as RAM_CONST_ATTR.
    
    The entry point has changed from call_user_start() to user_start_trampoline()
    in order for the exception handler to be installed early enough.
