    13 This BSP supports four variants: `xilinx-zynqmp-ilp32-qemu`,
    14 `xilinx-zynqmp-lp64-qemu`, `xilinx-zynqmp-ilp32-zu3eg`, and
    15 `xilinx-zynqmp-lp64-zu3eg`. Platform-specific hardware initialization is
    16 performed by ARM Trusted Firmware (ATF). Other basic hardware initialization is
    17 performed by the BSP. These BSPs support the GICv2 interrupt controller present
    18 in all ZynqMP systems. The zu3eg BSPs have also been tested to be fully
    19 functional on zu2cg boards and should also work on any other ZynqMP chip variant
    20 since the Processing Subsystem (PS) does not vary among chip variants other than
    21 the number of CPU cores available.
     14This BSP family supports the following variants:

     16* `xilinx-zynqmp-ilp32-qemu`

    3353recommended to use the u-boot BOOT.bin that comes with the PetaLinux prebuilts
    3454for the board in question.
     55
     56Some systems such as the CFC-400X may require a bitstream to be loaded into the
     57FPGA portion of the chip to operate as expected. This bitstream must be loaded
     58before RTEMS begins operation since accesses to programmable logic (PL) memory
     59space can cause the CPU to hang if the FPGA is not initialized. This can be
     60performed as part of BOOT.bin or by a bootloader such as u-boot. Loading
     61bitstreams from RTEMS has not been tested on the ZynqMP platform and requires
     62additional libraries from Xilinx.
