i don't think the ROM is being used. at least i am not aware of anyone who would have developed a ROM code for Ducati... so i don't think you can use the ROM. as for the RAM if you refer to what's called 'SL2 memory', it's being used by the codecs (IVAHD), it's just RAM that can be used freely if you don't use IVAHD. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
