MIPS: do not compile generic functions for CONFIG_CAVIUM_OCTEON_SOC
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.
