+       * config/tc-arm.c (arm_ext_v6t2_v8m): New feature for instructions
+       shared between ARMv6T2 and ARMv8-M.
+       (move_or_literal_pool): Check mov.w/mvn and movw availability against
+       arm_ext_v6t2 and arm_ext_v6t2_v8m respectively instead of checking
+       arm_arch_t2.
+       (do_t_branch): Error out for wide conditional branch instructions if
+       targetting ARMv8-M Baseline.
+       (non_v6t2_wide_only_insn): Add the logic for new wide-only instructions
+       in ARMv8-M Baseline.
+       (wide_insn_ok): New function.
+       (md_assemble): Use wide_insn_ok instead of non_v6t2_wide_only_insn and
+       adapt error message for unsupported wide instruction to ARMv8-M
+       Baseline.
+       (insns): Reorganize instructions shared by ARMv8-M Baseline and
+       ARMv6t2 architecture.
+       (arm_cpus): Set feature bit ARM_EXT2_V6T2_V8M for marvell-pj4 and
+       marvell-whitney cores.
+       (arm_archs): Define armv8-m.base architecture.
+       (cpu_arch_ver): Define ARM_ARCH_V8M_BASE architecture version.
+       (aeabi_set_public_attributes): Add logic to set Tag_CPU_arch to 17 for
+       ARMv8-M Mainline.  Set Tag_DIV_use for ARMv8-M Baseline as well.
