2025-12-08lib: utils/cache: Handle last-level cache correctly in fdt_cache_add()Nick Hu
The fdt_cache_add() helper attempts to retrieve the next-level cache and returns SBI_ENOENT when there is none. Since this condition only indicates that the current cache is the last-level cache, the helper should not treat it as an error.
