Hi Hiroshi, > Yes, "dspgateway" won't support OMAP3 but if I remember > correctly that TWL is already in OMAP2? and also does Camera > use the same mechanism of this MMU? This may be benefit or a > must, I guess.. I agree. If we are certain that camera driver or some other driver uses MMU the same way bridge does and the MMU architecture is the same, it makes sense to make this generic code. My point is that if DSPGateway doesn't use TWL, it will not benefit from using the Bridge MMU code which has TWL enabled. On the other hand, we have a usecase for mailbox driver being used by multiple IPC stacks. Hence it makes sense to make this code generic.
