+- Changed the memory initialized for the PDEC Config Memory and the PDEC RAM by using `mmap`
+  directly and ignoring UIO. This makes the OBSW compatible to a device tree update, where those
+  memory segments are marked reserved and are thus not properly accessible through the UIO API
+  anymore. This change should be downwards compatible to older device trees.
