This PR adds support for PINE64 Ox64 64-bit RISC-V SBC, based on Bouffalo Lab BL808 SoC (T-Head C906 Core). Most of the code is derived from NuttX for Star64 JH7110. The source files are explained in the articles here: https://github.com/lupyuen/nuttx-ox64 ### Modified Files `boards/Kconfig`: Added Ox64 board ### New Files in boards/risc-v/bl808/ox64 `src/bl808_appinit.c`: Startup Code `include/board.h`: Ox64 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`: Ox64 Makefile `src/Makefile`: Ox64 Makefile `Kconfig`: Ox64 Config `configs/nsh/defconfig`: Build Config for `ox64:nsh` ### Updated Documentation `platforms/risc-v/bl808/index.rst`: New page for Bouffalo Lab BL808 SoC `platforms/risc-v/bl808/boards/ox64/index.rst`: Building and booting NuttX for Ox64 `platforms/risc-v/jh7110/boards/star64/index.rst`: Fix typo
