-----------------------------
1. Building U-Boot
------------------
The SBC8641D code is known to build using ELDK 4.1.
$ make sbc8641d_config
Configuring for sbc8641d board...
$ make
2. Switch and Jumper Settings
-----------------------------
All Jumpers & Switches are in their default positions. Please refer to
the board documentation for details. Some settings control CPU voltages
and settings may change with board revisions.
3. Known limitations
--------------------
PCI:
The PCI command may hang if no boards are present in either slot.
