The only currently supported configuration uses an ARMv4 StrongARM but still requires building for ARMv3 because of the board design not supporting 16-bit data access. ARMv3 support has been removed in gcc-9, and the gcc-8 release is already old but still supported for building the kernel. The only set of machines that lacks support for 16-bit load/store instructions (Alpha EV5 and older) was recently removed from the kernel. Since there is little hope of this being maintainable much longer, plan to remove it in early 2025 while it is still expected to mostly work.
