[coreboot] a question about reset16.lds

[ali hagigat]

SECTIONS {
    /* Trigger an error if I have an unuseable start address */
    _bogus = ASSERT(_start >= 0xffff0000, "_start too low. Please
decrease CONFIG_ROM_IMAGE_SIZE");
    _ROMTOP = 0xfffffff0;
    . = _ROMTOP;
    .reset . : {
    	*(.reset)
    	. = 15 ;
    	BYTE(0x00);
    }
}

What does (.=15;) mean? It seems a mistake! and can be: . = .+1;
