From 5e0c68edad7d47438721e862fd772710dffca9b4 Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Wed, 21 Mar 2018 15:58:49 +0300 Subject: [PATCH] ARC: Introduce is_isa_X() functions Introduce is_isa_arcv2() and is_isa_arcompact() functions. These functions only check configuration options and return compile-time constant so they can be used instead of #ifdef's to to write cleaner code. Now we can write: -------------->8--------------- if (is_isa_arcv2()) ioc_configure(); -------------->8--------------- instead of: -------------->8--------------- ifdef CONFIG_ISA_ARCV2 ioc_configure(); endif -------------->8--------------- Signed-off-by: Eugeniy Paltsev Signed-off-by: Alexey Brodkin --- arch/arc/include/asm/arcregs.h | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/arch/arc/include/asm/arcregs.h b/arch/arc/include/asm/arcregs.h index 67f4163..3a51314 100644 --- a/arch/arc/include/asm/arcregs.h +++ b/arch/arc/include/asm/arcregs.h @@ -8,6 +8,7 @@ #define _ASM_ARC_ARCREGS_H #include +#include /* * ARC architecture has additional address space - auxiliary registers. @@ -88,6 +89,16 @@ /* ARCNUM [15:8] - field to identify each core in a multi-core system */ #define CPU_ID_GET() ((read_aux_reg(ARC_AUX_IDENTITY) & 0xFF00) >> 8) + +static const inline int is_isa_arcv2(void) +{ + return IS_ENABLED(CONFIG_ISA_ARCV2); +} + +static const inline int is_isa_arcompact(void) +{ + return IS_ENABLED(CONFIG_ISA_ARCOMPACT); +} #endif /* __ASSEMBLY__ */ #endif /* _ASM_ARC_ARCREGS_H */ -- 2.7.4
