Sure there is a way. Your best option is to use a section just for your function:

int start(void) __attribute__((section(".start")));

int start(void)
{
}

And then in the linker script:

SECTIONS
{
    . = 0x1234; // <---- put here your address
    .start : 
    {
        *(.start)
    }
}

Or something like that (it's been quite a long time since I used that).
