Hi Patrick,

You can look at the Oxford pcie card and 8250MEM drivers for reference:
src/drivers/uart/oxpcie*
src/drivers/uart/uart8250mem*

Hello everybody,

Do you think that it would be possible to output the console messages
from coreboot (seabios) on another UART port (strapped to be visible on
Memory-based space or IO Space) connected on a PCIe slot ?

I've purchased a StarTech UART board with an OXPCIe952 chip, with the
same IDs as visible in ./src/drivers/uart/oxpcie.c.

On
http://www.coreboot.org/Serial_console#PCIe.2FMini_PCIe_based_serial_cards,
what is behind the sentence:
"In order to use the card for romstage debugging, minimal setup of the
PCIe bridge and the MPEX2S952 have to be added to romstage.c" ?

Thanks in advance.
Best regards,
Patrick Agrain
