Fwd: 8250 memory mapped UART

Hi Experts,

I am using GRUB2 on intel apollo lake board. This board does not have IO mapped uart instead it has 8250 memory mapped UART. 

GRUB2 does not recognize memory mapped uart and gives error ("serial port COM0 not found). There is a 8250 memory mapped driver available in coreboot. Is it possible to port that driver to Grub2?
