zynq: add new target
Add support for Xilinx ZC702 Dev board Zynq target is using 4.4 kernel and mainline 2016.1 u-boot. Patch is tested with Xilinx ZC702 Dev board with SD boot mode. known issues: - no QSPI driver in 4.4 kernel: no QSPI flash support - USB is not working in 4.4 kernel Signed-off-by: Jason Wu <jason.wu.misc@gmail.com> create mode 100644 package/boot/uboot-zynq/Makefile create mode 100644 target/linux/zynq/Makefile create mode 100644 target/linux/zynq/base-files.mk create mode 100755 target/linux/zynq/base-files/etc/board.d/02_network create mode 100644 target/linux/zynq/base-files/etc/config/network create mode 100644 target/linux/zynq/base-files/etc/inittab create mode 100644 target/linux/zynq/config-4.4 create mode 100644 target/linux/zynq/image/Makefile create mode 100755 target/linux/zynq/image/mkits.sh create mode 100644 target/linux/zynq/patches-4.4/0001-arm-dts-zynq-zc702.dts-Set-default-rdinit-to-sbin-in.patch create mode 100644 target/linux/zynq/profiles/zc702.mk SVN-Revision: 48697
