Qemu Xilinx ZynqMP
==================
-This BSP supports four variants: `xilinx-zynqmp-ilp32-qemu`,
-`xilinx-zynqmp-lp64-qemu`, `xilinx-zynqmp-ilp32-zu3eg`, and
-`xilinx-zynqmp-lp64-zu3eg`. Platform-specific hardware initialization is
-performed by ARM Trusted Firmware (ATF). Other basic hardware initialization is
-performed by the BSP. These BSPs support the GICv2 interrupt controller present
-in all ZynqMP systems. The zu3eg BSPs have also been tested to be fully
-functional on zu2cg boards and should also work on any other ZynqMP chip variant
-since the Processing Subsystem (PS) does not vary among chip variants other than
-the number of CPU cores available.

+Some systems such as the CFC-400X may require a bitstream to be loaded into the
+FPGA portion of the chip to operate as expected. This bitstream must be loaded
+before RTEMS begins operation since accesses to programmable logic (PL) memory
