[coreboot] coreboot.rom

[ali hagigat]

How the file coreboot.rom is written on BIOS chip logically? Suppose
our BIOS chip is 1 mega bytes. We should read first byte from the
beginning of the file and write it to the address zero of BIOS chip
and continue this way?

I checked the content of build/coreboot.rom and the last byte was
0x0a!! Which is written probably on the top of our EEPROM. Right?
but src/arch/i386/init/ldscript.ld specifies the last byte as 0x00!!
SECTIONS {
    _ROMTOP = 0xfffffff0;
    . = _ROMTOP;
    .resetvector . : {
    	*(.reset)
                . = 15 ;
                BYTE(0x00);
    }
}

Please help me with this puzzle. Thank you.
