[coreboot] How to add additional LPC decode ranges to Baytrail.

[Jose Trujillo]

Hello Dear Community:

I am trying to enable UART port addresses 3e8 and 2e8 to one of my 2 superios I have attached to the same LPC port.

I need 4 UART ports.

Both superio chips work if I set 3f8 and 2f8 but one at the time (i need to disable the other SIO).

Today I was looking at baytrail code but I got lost; I did not even find how the code add 3f8/2f8 in order to do the same to 3e8/2e8.

i found the function "lpc_open_pmio_window()" but this didn't build for me on Baytrail.

Do somebody know to to add LPC decode ranges for 3e8 and 2e8 on Baytrail?

Please let me know.

Jose Trujillo.
