The arm/xilinx-zynqmp is a BSP for only the 32-bit arm support of the Zynq Ultrascale+ MPSOC specifically tested/used on the Ultra96. It was contributed by Dornerworks. I guess this is a little confusing, because now we also have bsps/aarch64/xilinx-zynqmp, which provides the 64-bit support. At some point, we should be able to deprecate/drop the arm/xilinx-zynqmp with the ability to configure the aarch64/xilinx-zynqmp to only run in aarch32 mode. > Also, everything still seems to be organized by architecture, the board. >> How do you want the Zynq Ultrascale organized?
