Subject: mapping 2TB bar in linux kernel

Hi,
   I have a need to map a 2TB bar in linux kernel.

BIOS does not enumerate large bar and it seems theoretically it is
possible to enumerate from Linux kernel, do necessary chipset
programming so that entire 2TB memory can be accessed from Linux
kernel.

Has anyone attempted this? Is there any patch that can be used.

Any input is appreciated.

Regards,
