ed by Philip Kirkpatrick):<br>
Refactoring:<br>
* import Xilinx code before modification<br>
* better use the existing Xilinx support code<br>
Other:<br>
* An additional patch to add cache support (also from Philip) has been<br>
  integrated and refactored<br>
<br>
This has been tested on Xilinx's QEMU with Xilinx's device tree<br>
definitions using the following command line options to QEMU:<br>
-no-reboot -nographic -M arm-generic-fdt -serial null -serial mon:stdio \<br>
-device loader,file=<RTEMS exe path>,cpu-num=4 \<br>
-device loader,addr=0xff5e023c,data=0x80088fde,data-len=4 \<br>
-device loader,addr=0xff9a0000,data=0x80000218,data-len=4 \<br>
-hw-dtb <XLNX DTB dir>/LATEST/SINGLE_ARCH/board-zynqmp-zcu102.dtb \<br>
-m 4096 -display none<br>
<br>
hello.exe and ts-validation-cache.exe operated as expected. Ticker<br>
produced output, but the timing and content was incorrect on QEMU.<br>
