Cortex-R7. The R7 has many similarities to the A9 and though the ACTLR layout is not identical, the bits associated with cache operations broadcasting and SMP modes are the same for A9, A5 and R7 (Though in the A-class processors the same bits toggle TLB-ops broadcasting as well as cache-ops) Signed-off-by: Jonathan Austin Reviewed-by: Will Deacon CC: Catalin Marinas CC: Stephen Boyd --- diff --git a/arch/arm/mm/proc-v7.S b/arch/arm/mm/proc-v7.S index a851e3433afe..f85ae8cad17f 100644 --- a/arch/arm/mm/proc-v7.S +++ b/arch/arm/mm/proc-v7.S @@ -159,7 +159,8 @@ ENDPROC(cpu_v7_do_resume) */ __v7_ca5mp_setup: __v7_ca9mp_setup: - mov r10, #(1 << 0) @ TLB ops broadcasting +__v7_cr7mp_setup: + mov r10, #(1 << 0) @ Cache/TLB ops broadcasting b 1f __v7_ca7mp_setup: __v7_ca15mp_setup: @@ -418,6 +419,16 @@ __v7_pj4b_proc_info: __v7_proc __v7_pj4b_setup .size __v7_pj4b_proc_info, . - __v7_pj4b_proc_info + /* + * ARM Ltd.
