From fcfddfd50472d7ce84ef4e2853242bbeb7b37325 Mon Sep 17 00:00:00 2001 From: Jeroen Hofstee Date: Mon, 23 Jun 2014 22:07:04 +0200 Subject: ARM: cache_v7: use __weak This is not only more readable but also prevents a warning about a missing prototype. The prototypes which are actually missing are added. cc: Albert Aribaud Signed-off-by: Jeroen Hofstee Reviewed-by: Tom Rini --- arch/arm/lib/cache-cp15.c | 9 ++------- arch/arm/lib/cache.c | 13 +++---------- 2 files changed, 5 insertions(+), 17 deletions(-) (limited to 'arch/arm/lib') diff --git a/arch/arm/lib/cache-cp15.c b/arch/arm/lib/cache-cp15.c index 8642010..5fdfdbf 100644 --- a/arch/arm/lib/cache-cp15.c +++ b/arch/arm/lib/cache-cp15.c @@ -14,11 +14,9 @@ DECLARE_GLOBAL_DATA_PTR; -void __arm_init_before_mmu(void) +__weak void arm_init_before_mmu(void) { } -void arm_init_before_mmu(void) - __attribute__((weak, alias("__arm_init_before_mmu"))); __weak void arm_init_domains(void) { @@ -44,14 +42,11 @@ void set_section_dcache(int section, enum dcache_option option) page_table[section] = value; } -void __mmu_page_table_flush(unsigned long start, unsigned long stop) +__weak void mmu_page_table_flush(unsigned long start, unsigned long stop) { debug("%s: Warning: not implemented\n", __func__); } -void mmu_page_table_flush(unsigned long start, unsigned long stop) - __attribute__((weak, alias("__mmu_page_table_flush"))); - void mmu_set_region_dcache_behaviour(u32 start, int size, enum dcache_option option) { diff --git a/arch/arm/lib/cache.c b/arch/arm/lib/cache.c index 4f6b9f0..4e597a4 100644 --- a/arch/arm/lib/cache.c +++ b/arch/arm/lib/cache.c @@ -9,7 +9,7 @@ #include -void __flush_cache(unsigned long start, unsigned long size) +__weak void flush_cache(unsigned long start, unsigned long size) { #if defined(CONFIG_ARM1136) @@ -31,28 +31,21 @@ void __flush_cache(unsigned long start, unsigned long size) #endif /* CONFIG_ARM926EJS */ return; } -void flush_cache(unsigned long start, unsigned long size) - __attribute__((weak, alias("__flush_cache"))); /* * Default implementation: * do a range flush for the entire range */ -void __flush_dcache_all(void) +__weak void flush_dcache_all(void) { flush_cache(0, ~0); } -void flush_dcache_all(void) - __attribute__((weak, alias("__flush_dcache_all"))); - /* * Default implementation of enable_caches() * Real implementation should be in platform code */ -void __enable_caches(void) +__weak void enable_caches(void) { puts("WARNING: Caches not enabled\n"); } -void enable_caches(void) - __attribute__((weak, alias("__enable_caches"))); -- cgit v1.1
