boards/risc-v/eic7700x/starpro64: Add support for PINE64 StarPro64 SBC (ESWIN EIC7700X SoC)
This PR adds support for the PINE64 StarPro64 64-bit RISC-V SBC, based on ESWIN EIC7700X SoC. Most of the code was derived from NuttX for Milk-V Duo S (SOPHGO SG2000). The modified code is explained here: https://lupyuen.github.io/articles/starpro64#appendix-port-nuttx-to-starpro64 Modified Files: boards/Kconfig: Added StarPro64 board New Files in boards/risc-v/eic7700x/starpro64: src/eic7700x_appinit.c: Startup Code include/board.h: StarPro64 Definitions include/board_memorymap.h: Memory Map src/etc/init.d/rc.sysinit, rcS: Startup Script src/.gitignore: Ignore the tmp filesystem scripts/ld.script: Linker Script scripts/Make.defs: StarPro64 Makefile src/Makefile: StarPro64 Makefile Kconfig: StarPro64 Config configs/nsh/defconfig: Build Config for starpro64:nsh Signed-off-by: Lup Yuen Lee <luppy@appkaki.com>
