Set the toolchain's ARM CPU and FPU architectures by utilizing' gcc's --with-cpu / --with-fpu configure options that: "Specify which cpu variant the compiler should generate code for by default. cpu will be used as the default value of the -mcpu= switch." This will resolve the following kernel compilation failures under gcc 8.x on ARM because the kernel wants to set (possibly conflicting) optimization flags. .../ccyVnmrs.s:204: Error: selected processor does not support `dmb ish' in ARM mode .../ccyVnmrs.s:215: Error: architectural extension `mp' is not allowed for the current base architecture .../ccyVnmrs.s:216: Error: selected processor does not support `pldw [r4]' in ARM mode Because this is a big change, the .config and toolchain need to be refreshed (as in removed and regenerated).
