There is not formal documentation on how to do it.  Porting RTL shouldn't
be too difficult, we too great care to ensure that every PPC architecture
running Linux would run RTL with little or no modification.

As for porting the kernel to this board, that would probably take the
larger portion of time.  Debugging the system during bring-up would be
difficult.

How minimal of a linux system are you looking at?

} Does any documentation exist on how to configure and port an embedded
} networked version of rtlinux to a unique PowerPC board? No local
} secondary storage. This would be a minimal embedded soft real-time RTOS
} using rtlinux?
} 
} Essentially, the system would have a PowerPC 603e processor, memory
} controller, timer, and interrupt controller and nothing else (can't do
} much useful with this system!). It would be debugged using a back door
} into the processor (JTAG/COP port).  This is the minimal reusable
} component.  Then, TCP/IP would be added with an Ethernet network I/O
} driver. (It could have a serial interface for the console I/O, if
} absolutely necessary.)
} 
} Any idea on how much effort (man days) it would take to create a stable
} version of this initial TCP/IP networked RTOS for MPC603e?
