New Revision: 752

Modified:
   trunk/board_enable.c
Log:
Board enable for Shuttle FN25 (SN25P).

Shuttle SFF PC is SN25P, board FN25, AMD socket 939 with an nForce4
chipset.

Config register 0x92 on the ISA bridge needs to be cleared for TBL#
to be raised. No information about individual bits of this register
is currently available.
