No, I was wrong. OMAP_MBOX_FWK is forced to "Y" in our config and I thought DSPBRIDGE forced this. But DSPBRIDGE isn't even active in our configuration. I cannot turn OMAP_MBOX_FWK off, it's forced to Y, and I'm currently trying to figure out which part of ti81xx-psp-linux-2.6.37's wicked configuration is causing this. >>>> What do you mean by Ne/Ce? >>> >>> Netra/Centaurus, dm81xx, c6a81xx, am38xx, am39xx or whatever TI is calling >>> it nowadays. >> >> We're on a "TI DaVinci DM8148", featuring a cortex-a8 combined with a >> C674x DSP. > > So a centaurus family SoC. Thanks for the clarification :) TI didn't approach us with any of the terms you mentioned.

Also, DSPBRIDGE depends on OMAP3, which we don't have (dm8148 is a "OMAP2PLUS"). So I was wrong with DSPBRIDGE forcing OMAP_MBOX_FWK. OMAP_MBOX_FWK is just active and I can't switch it off.
