In addition to LDD3 (for 2.6 kernels, or the freely available LDD2 for 2.4 
kernels), you might want to look at some existing Linux drivers that are
based on "bare metal" / "no OS" drivers.  The ones I know of are for Xilinx
peripherals, for example (within the Linux kernel tree),
- ./drivers/net/xilinx_enet
- ./drivers/char/xilinx_uartlite
- ./drivers/char/xilinx_gpio

Where can I find the ./drivers/net/xilinx_enet, ... etc files.
I can not find them in the 2.6.14.2 tree

They are in the linuxppc-2.4 tree. Try
rsync -avz --delete source.mvista.com::linuxppc-2.4 <directory>
