--- v2: Forget to also add config file
v3: Change name for serial driver Remove lowlevel_init from board folder Remove XPSS part from timer baseaddr Change name for Zynq gem driver Clean coding style Remove mac + ip addresses from config file Remove additional PHYs
v4: Move reset_cpu to cpu folder Remove empty board_late_init Enable SERIAL_MULTI Setup SYS_TEXT_BASE Changed eth initialization --- board/xilinx/zynq/Makefile | 54 +++++++++++++++++++++ board/xilinx/zynq/board.c | 54 +++++++++++++++++++++ boards.cfg | 1 + include/configs/zynq.h | 112 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 221 insertions(+), 0 deletions(-) create mode 100644 board/xilinx/zynq/Makefile create mode 100644 board/xilinx/zynq/board.c create mode 100644 include/configs/zynq.h
