Data-abort exception while trying to boot skalk/linux imx-53 branch with genode trustzone

[Abhishek Kumar]

Hello
I am trying to run linux in normal world on genode trustzone. I have
changed the run-script of genode to copy the uImage generated from
skalk/linux's imx-53 branch instead of downloading (default). I am making
uImage with following command:

make uImage LOADADDR=0x70010000

while executing, genode stops after starting virtual machine with following
error trace:

```

```

Initially I thought I might be giving wrong load address while making
uImage, but it seems problem is not that. Can someone help me with what
might be possibly going wrong?

Thanks
Abhishek
