As far as I could see, this did not introduce any regression on my omap3630 device (omap_smc1 is used from omap3_invalidate_l2_cache_secure in my case). Looks good to me. > As part of this change, move to using the generic lowlevel_init.S for > omap3 as well. > > Signed-off-by: Nishanth Menon <[email protected]> > --- > arch/arm/cpu/armv7/omap-common/Makefile | 2 +- > arch/arm/cpu/armv7/omap-common/lowlevel_init.S | 2 ++ > arch/arm/cpu/armv7/omap3/board.c | 6 ++---- > arch/arm/cpu/armv7/omap3/lowlevel_init.S | 11 ----------- > arch/arm/include/asm/arch-omap3/sys_proto.h | 2 +- > 5 files changed, 6 insertions(+), 17 deletions(-) > > diff --git a/arch/arm/cpu/armv7/omap-common/Makefile > b/arch/arm/cpu/armv7/omap-common/Makefile > index 7695e16d36f5..f3725b267c99 100644 > --- a/arch/arm/cpu/armv7/omap-common/Makefile > +++ b/arch/arm/cpu/armv7/omap-common/Makefile > @@ -28,7 +28,7 @@ endif > > ifeq ($(CONFIG_OMAP34XX),) > obj-y += boot-common.o > -obj-y += lowlevel_init.o > endif > +obj-y += lowlevel_init.o > > obj-y += mem-common.o > diff --git a/arch/arm/cpu/armv7/omap-common/lowlevel_init.S > b/arch/arm/cpu/armv7/omap-common/lowlevel_init.S > index 9b24369e4dc1..7d0f09496d85 100644 > --- a/arch/arm/cpu/armv7/omap-common/lowlevel_init.S > +++ b/arch/arm/cpu/armv7/omap-common/lowlevel_init.S > @@ -16,11 +16,13 @@ > #include <asm/arch/spl.h> > #include <linux/linkage.h> > > +#ifndef CONFIG_OMAP34XX > ENTRY(save_boot_params) > ldr r1, =OMAP_SRAM_SCRATCH_BOOT_PARAMS > str r0, [r1] > bx lr > ENDPROC(save_boot_params) > +#endif > > ENTRY(omap_smc1) > PUSH {r4-r12, lr} @ save registers - ROM code may pollute > diff --git a/arch/arm/cpu/armv7/omap3/board.c > b/arch/arm/cpu/armv7/omap3/board.c > index 90d6ae7bb5f5..51abc4b09e36 100644 > --- a/arch/arm/cpu/armv7/omap3/board.c > +++ b/arch/arm/cpu/armv7/omap3/board.c > @@ -418,8 +418,7 @@ static void omap3_update_aux_cr_secure(u32 set_bits, u32 > clear_bits) > acr |= set_bits; > > if (get_device_type() == GP_DEVICE) { > - omap3_gp_romcode_call(OMAP3_GP_ROMCODE_API_WRITE_ACR, > - acr); > + omap_smc1(OMAP3_GP_ROMCODE_API_WRITE_ACR, acr); > } else { > struct emu_hal_params emu_romcode_params; > emu_romcode_params.num_params = 1; > @@ -459,8 +458,7 @@ static void omap3_update_aux_cr(u32 set_bits, u32 > clear_bits) > static void omap3_invalidate_l2_cache_secure(void) > { > if (get_device_type() == GP_DEVICE) { > - omap3_gp_romcode_call(OMAP3_GP_ROMCODE_API_L2_INVAL, > - 0); > + omap_smc1(OMAP3_GP_ROMCODE_API_L2_INVAL, 0); > } else { > struct emu_hal_params emu_romcode_params; > emu_romcode_params.num_params = 1; > diff --git a/arch/arm/cpu/armv7/omap3/lowlevel_init.S > b/arch/arm/cpu/armv7/omap3/lowlevel_init.S > index 78577b1d1c75..84591b8b5bab 100644 > --- a/arch/arm/cpu/armv7/omap3/lowlevel_init.S > +++ b/arch/arm/cpu/armv7/omap3/lowlevel_init.S > @@ -27,17 +27,6 @@ ENTRY(save_boot_params) > ENDPROC(save_boot_params) > #endif > > -ENTRY(omap3_gp_romcode_call) > - PUSH {r4-r12, lr} @ Save all registers from ROM code! > - MOV r12, r0 @ Copy the Service ID in R12 > - MOV r0, r1 @ Copy parameter to R0 > - mcr p15, 0, r0, c7, c10, 4 @ DSB > - mcr p15, 0, r0, c7, c10, 5 @ DMB > - .word 0xe1600070 @ SMC #0 to enter monitor - hand assembled > - @ because we use -march=armv5 > - POP {r4-r12, pc} > -ENDPROC(omap3_gp_romcode_call) > - > /* > * Funtion for making PPA HAL API calls in secure devices > * Input: > diff --git a/arch/arm/include/asm/arch-omap3/sys_proto.h > b/arch/arm/include/asm/arch-omap3/sys_proto.h > index bcf92fbe658b..c06605d533d3 100644 > --- a/arch/arm/include/asm/arch-omap3/sys_proto.h > +++ b/arch/arm/include/asm/arch-omap3/sys_proto.h > @@ -73,6 +73,6 @@ void power_init_r(void); > void dieid_num_r(void); > void get_dieid(u32 *id); > void do_omap3_emu_romcode_call(u32 service_id, u32 parameters); > -void omap3_gp_romcode_call(u32 service_id, u32 parameter); > +void omap_smc1(u32 service, u32 val); > u32 warm_reset(void); > #endif
