riscv: make t-head erratas depend on MMU
Both basic extensions of SVPBMT and ZICBOM depend on CONFIG_MMU. Make the T-Head errata implementations of the similar functionality also depend on it to prevent build errors. Fixes: a35707c3d850 ("riscv: add memory-type errata for T-Head") Fixes: d20ec7529236 ("riscv: implement cache-management errata for T-Head SoCs") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Guo Ren <guoren@kernel.org> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20220907154932.2858518-1-heiko@sntech.de Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
