The toolchain was obtained from https://github.com/TUD-OS/morbo.
For Genode bender was modified so that binaries are only relocated up
to 2G physical. Additional, relocation can be limited to 256M for sel4.
The microcode tools expect to find a module named micro.code which contains
to 2G physical. Additionally, relocation can be limited to 256M for sel4.
Optionally, the tool may load Intel microcode if configured via commandline.
