libcpu: riscv: declare external symbols inside

2025-04-11T06:15:12Z

libcpu/risc-v/common64/mmu.c uses the external symbol "__bss_end" (this symbol generally is defined in the link script file) and depends on the extern declaration of this symbol in the bsp's "board.h". This is not a problem in implementation, but it is not a good habit. If this extern symbol is used locally, just declare it locally should be better. In this way, there will be no dependency of the kernel core on the bsp header file. And there will be no special requirements for the bsp board code, such as the need to make extern declarations for these "__bss_end" symbols in "board.h". This patch currently only explicitly externly declares "__bss_end" inside libcpu itself. The code of "#include " is kept, because the modification involved is too large, it is necessary to clean up the bsp involved before cleaning this include code line uniformly.
