Physical memory allocation to L4linux

Hey Martin,

thanks for that tip. How do I use this device for L4linux though (and only for it)? I am not sure where memory allocation occurs when L4linux faults or if it is pre-allocated completely to L4linux. 

Best,
ramya

MYRAM => new Device() {
   .hid= "myram";
   new-res Mmio(0x10000000 .. 0x13FFFFFF, 0xC000);
}
