gigabyte/ga-b75m-d3h: Add new Intel mainboard
This is based on LENOVO X230 port.
Board boots to linux via SATA or USB.
All USB ports are working.
Remaining Issues:
1. Native raminit sometimes fails with "timC write discovery failed"
even without changing the ram configuration. I suggest
altering the native raminit code so that it reboots
if that message appears to give a chance for the
boot process to recover.
2. VGA does not work.
Native graphics initialization only supports LVDS and
the VGA Option ROM still hangs when run in SeaBIOS.
