This BSP supports four variants: `xilinx-zynqmp-ilp32-qemu`, This BSP family supports the following variants:
`xilinx-zynqmp-lp64-qemu`, `xilinx-zynqmp-ilp32-zu3eg`, and
`xilinx-zynqmp-lp64-zu3eg`. Platform-specific hardware initialization is * `xilinx-zynqmp-ilp32-qemu`
performed by ARM Trusted Firmware (ATF). Other basic hardware initialization is
performed by the BSP. These BSPs support the GICv2 interrupt controller present * `xilinx-zynqmp-lp64-qemu`
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 * `xilinx-zynqmp-ilp32-zu3eg`
since the Processing Subsystem (PS) does not vary among chip variants other than
the number of CPU cores available. * `xilinx-zynqmp-lp64-zu3eg`

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
space can cause the CPU to hang if the FPGA is not initialized. This can be
performed as part of BOOT.bin or by a bootloader such as u-boot. Loading
bitstreams from RTEMS has not been tested on the ZynqMP platform and requires
additional libraries from Xilinx.
