We want to use the rest function in two places (board_f and board_r), so declare the functions in watchdog.h. Signed-off-by: Simon Glass --- Changes in v6: - Fix up watchdog support for m68k and sh Changes in v5: - Avoid using static declaration for init_func_watchdog_reset() Changes in v4: None Changes in v3: None Changes in v2: None arch/m68k/lib/board.c | 1 + arch/powerpc/lib/board.c | 11 ++--------- arch/sh/lib/board.c | 1 + include/watchdog.h | 18 ++++++++++++++++++ 4 files changed, 22 insertions(+), 9 deletions(-) diff --git a/arch/m68k/lib/board.c b/arch/m68k/lib/board.c index b676255..adaccfe 100644 --- a/arch/m68k/lib/board.c +++ b/arch/m68k/lib/board.c @@ -80,6 +80,7 @@ extern ulong __init_end; extern ulong __bss_end; #if defined(CONFIG_WATCHDOG) +# undef INIT_FUNC_WATCHDOG_INIT # define INIT_FUNC_WATCHDOG_INIT watchdog_init, # define WATCHDOG_DISABLE watchdog_disable diff --git a/arch/powerpc/lib/board.c b/arch/powerpc/lib/board.c index 0b23d30..acb6fdb 100644 --- a/arch/powerpc/lib/board.c +++ b/arch/powerpc/lib/board.c @@ -237,25 +237,18 @@ static int init_func_spi(void) /***********************************************************************/ #if defined(CONFIG_WATCHDOG) -static int init_func_watchdog_init(void) +int init_func_watchdog_init(void) { puts(" Watchdog enabled\n"); WATCHDOG_RESET(); return 0; } -#define INIT_FUNC_WATCHDOG_INIT init_func_watchdog_init, - -static int init_func_watchdog_reset(void) +int init_func_watchdog_reset(void) { WATCHDOG_RESET(); return 0; } - -#define INIT_FUNC_WATCHDOG_RESET init_func_watchdog_reset, -#else -#define INIT_FUNC_WATCHDOG_INIT /* undef */ -#define INIT_FUNC_WATCHDOG_RESET /* undef */ #endif /* CONFIG_WATCHDOG */ /* diff --git a/arch/sh/lib/board.c b/arch/sh/lib/board.c index 34d7881..6e43acf 100644 --- a/arch/sh/lib/board.c +++ b/arch/sh/lib/board.c @@ -65,6 +65,7 @@ static int sh_flash_init(void) #if defined(CONFIG_WATCHDOG) extern int watchdog_init(void); extern int watchdog_disable(void); +# undef INIT_FUNC_WATCHDOG_INIT # define INIT_FUNC_WATCHDOG_INIT watchdog_init, # define WATCHDOG_DISABLE watchdog_disable #else diff --git a/include/watchdog.h b/include/watchdog.h index 8c92a0b..97ec186 100644 --- a/include/watchdog.h +++ b/include/watchdog.h @@ -27,6 +27,24 @@ #ifndef _WATCHDOG_H_ #define _WATCHDOG_H_ +#if !defined(__ASSEMBLY__) +/* + * Reset the watchdog timer, always returns 0 + * + * This function is here since it is shared between board_f() and board_r(), + * and the legacy arch//board.c code. + */ +int init_func_watchdog_reset(void); +#endif + +#ifdef CONFIG_WATCHDOG +#define INIT_FUNC_WATCHDOG_INIT init_func_watchdog_init, +#define INIT_FUNC_WATCHDOG_RESET init_func_watchdog_reset, +#else +#define INIT_FUNC_WATCHDOG_INIT +#define INIT_FUNC_WATCHDOG_RESET +#endif + #if defined(CONFIG_HW_WATCHDOG) && defined(CONFIG_WATCHDOG) # error "Configuration error: CONFIG_HW_WATCHDOG and CONFIG_WATCHDOG can't be used together." #endif
