This patch set adds a new board support package to enable RTEMS to run as a guest virtual machine in AArch32 mode on the Xen hypervisor for ARMv8 platforms. This required two changes to the shared arm code: add a zImage boot header to start.S and umasking of the generic timer in the ISR.
This BSP was tested using the Virtuosity distro (maintained by Dornerworks) running on a Xilinx ZCU102 development board. I would like to implement a simulator for this platform to enable automated testing with mainline Xen, but it is currently a work-in-progress.
