I think we just want to be careful that it doesn't become a dumping ground for anything and everything SoC related whether the information is useful or not. I think each piece of exposed information should have a genuine use case, not just "because we can". ~Ryan -- Bluewater Systems Ltd - ARM Technology Solution Centre Ryan Mallon 5 Amuri Park, 404 Barbadoes St ryan at bluewatersys.com PO Box 13 889, Christchurch 8013 http://www.bluewatersys.com New Zealand Phone: +64 3 3779127 Freecall: Australia 1800 148 751 Fax: +64 3 3779135 USA 1800 261 2934
