MIPS provides multiple definitions for the following functions: fw_init_cmdline __delay __udelay __ndelay memmove __rmemcpy memcpy __copy_user The generic ones are defined in lib-y objects, which are overridden by the Octeon ones when CONFIG_CAVIUM_OCTEON_SOC is enabled. The use of EXPORT_SYMBOL in static libraries potentially causes a problem for the llvm linker [1]. So, I want to forcibly link lib-y objects to vmlinux when CONFIG_MODULES=y. As a groundwork, we must fix multiple definitions that have previously been hidden by lib-y. If you look at lib/string.c, arch can define __HAVE_ARCH_* to opt out the generic implementation. Similarly, this commit adds CONFIG_HAVE_PLAT_* to allow a platform to opt out the MIPS generic code.
