The port had one board directory holding one board, with everything in it whether it described the SoC or the PCB. A second EIC7700X board follows, so this adopts the common-plus-board layout NuttX provides, as mpfs uses. boards/risc-v/eic7700x/common holds what is true of the SoC: the boot path that mounts the RAM disk and /proc before calling the board's own bring up, the linker script, the start up scripts and the image builder. ARCH_CHIP_EIC7700X selects ARCH_BOARD_COMMON, so the symlinks the build makes always point at code that compiles. The board directory keeps what is a fact about the PCB: its own board.h and board_memorymap.h, since the include fallback is all or nothing, a bring up that owns the order its devices register in, and a board_config.h declaring what that bring up may call. The image builder moves to common/tools and derives its output name from the configuration. It computes the padding between the kernel and the RAM disk from _ebss rather than assuming 64 KiB, which fails once BSS grows past it: the disk lands below _ebss and the BSS clear zeroes it before anything searches for it. The StarPro64 configuration gains what the port now needs: four harts, 960 MiB of RAM, a larger task stack, a backtrace on assert, the system log in RAM for dmesg, and ELF applications, for which ARCH_CHIP_EIC7700X now selects ARCH_HAVE_ELF_EXECUTABLE. board.h loses its LED definitions. CONFIG_ARCH_LEDS is not set, nothing implements board_autoled_on(), and the indices they gave named no LED. The documentation pages gain the tags the template asks for.
