I agree with werner. You also should keep in mind that if too much functionality is implemented in the MPU, then more people will feel that they have to re-program it, resulting in the possibility to brick it, re-generating the need for some kind of MPU un-bricking feature, just like we have for the CPU. -- - Harald Welte <[EMAIL PROTECTED]> http://openmoko.org/ ============================================================================ Software for the world's first truly open Free Software mobile phone
