riscv: make t-head erratas depend on MMU
From: Heiko Stuebner <heiko@...> Date: Wed, 7 Sep 2022 17:43:36 +0200
Commit-Message
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@...> Signed-off-by: Heiko Stuebner <heiko@...>
