Revision: Beta_6_23_2015
The XZD Bare Metal guest provides a container for a bare metal application, so it can be used as a Xen guest on the Xilinx Zynq UltraScale+ MPSoC. The container provides virtual memory mapping, a stack, catching faults, and printing to Xen's console. The bare metal application will be limited to the memory that Xen provides it.
The source code for the XZD Bare Metal container can be found at: https://github.com/dornerworks/xzd_baremetal
