hp/abm: Add new mainboard
The hp/abm board is used in network/server applications.
Notes:
- The hp/abm board is headless and therefore does not define
CONFIG_GFXUMA, and does not require a video bios.
- The micro USB connector on the board edge is connected to COM4
(i.e. I/O=2E8h). Coreboot needs to be configured to use Index=3.
- If you are using SeaBIOS it would also need to be configured to
use the UART at I/O=2E8h.
- This board has been tested with headless installed versions of
Ubuntu 12.10 and Fedora 19.
