What makes this bug critical?

Patrik: This is very important since upstreaming a lot of the drivers depends on getting Device Tree ready first. Basically blocks all of drivers upstreaming.

@anmar So this bug is not going to be fixed ?

Anmar Oueja (anmar) wrote :

Hello Amit. The JB stable blob build uses the 3.4 kernel and will never switch to DT. However, the JB open tracking build (https://android-build.linaro.org/builds/~linaro-android/snowball-jb-gcc47-linaro-tracking-open/) does boot and will continue to book using DT. I recommend you close this bug as fixed released.
