As you know well some of the secure APIs work on CPU1 and others do not. I notice in other thread Russell made assumption about CPU1 being able to use all because it could run some. This is not the case. I'll re-add because of the many power states omap4 adds atop of standard 3 arm states there exists a lot of states and not all state transitions are valid. This will increase complexity of practical usage. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
