[PATCH v2 0/3] bsp/xen: support for Xen hypervisor

[Jeff Kubascik]

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.

Changes in v2:
- Squashed "bsp/xen: Create empty template BSP for Xen" commit
- Removed xen.inc and instead placed contents into xen_virtual.cfg
- Added "#ifdef ARM_GENERIC_TIMER_UNMASK_AT_TICK" to the workaround in
  clock-generic-timer.c
- Removed bsp README, will submit as a separate patch for the rtems-docs repo
- Changed local label to ".Lafter_header" in start.S
