OpenOCD script for making JATG debug

Hello :-)

I would like to get an OpenOCD script capable of loading a custom program
to SDRAM and run/debug it. The OpenOCD script have to initialize the SDRAM.

Also I need to have an OpenOCD script that let me flash code to NAND/NOR
and run/debug code.

We are working on an Open Source project, Lyre, a Digital Audio Player that
will run Rockbox firmware: http://lyre.sourceforge.net/

Thank you.
