Paging Simtec (if it reaches anyone), Vincent Sanders,
Teddy Wang at Silicon Motion:

Does any of you have an "Anubis" board so you can test GPIO
on this board before/after this patch and see if it checks out right?

I guess it's this board:
http://www.simtec.co.uk/products/BBD20EUROA/

Does anyone know of a commercially obtainable product using
SM501 with reasonable mainline Linux support so I can test it myself?

Getting a bit desperate...

Yours,
Linus Walleij
