Currently I am working towards items 1 and 3 of your list. Eventually I want to use this hardware to replace the flash content of my MSI Wind U100 netbook with free software (openec, coreboot, seabios, ipxe, grub2, etc). I want to keep my implementation sufficiently generic to allow for extensions like items 2, 4 and 5 of your list.
I am also interested in item 1. [1] But looks like you are far ahead of me. :) Currently I am waiting for my hardware to arrive. I ordered Open Workbench Logic Sniffer [2]. Do you think I can help you in your work?
I am interested to see if we eventually can port the Papilio code base to the OLS. It may be challenging: the OLS has a rather limited power supply and not too many GPIO pins. I do not own one, so you could help me with this.
For the time being I would recommend to learn more about writing proper RTL code in VHDL and play around with existing code examples [1]. You typically do not learn this stuff overnight, but I think it is worth the the effort.
Regards, Paul
