From 65f868cac6f7fd5c3ad02046574c19f8f4673255 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 23 May 2018 14:17:25 +0200 Subject: Add _CPU_Counter_frequency() Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456. --- bsps/arm/lpc32xx/start/bspstart.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'bsps/arm/lpc32xx/start/bspstart.c') diff --git a/bsps/arm/lpc32xx/start/bspstart.c b/bsps/arm/lpc32xx/start/bspstart.c index 7ade16bbb8..c535f766d7 100644 --- a/bsps/arm/lpc32xx/start/bspstart.c +++ b/bsps/arm/lpc32xx/start/bspstart.c @@ -26,6 +26,11 @@ #include #include +uint32_t _CPU_Counter_frequency(void) +{ + return LPC32XX_PERIPH_CLK; +} + CPU_Counter_ticks _CPU_Counter_read(void) { return lpc32xx_timer(); @@ -33,6 +38,5 @@ CPU_Counter_ticks _CPU_Counter_read(void) void bsp_start(void) { - rtems_counter_initialize_converter(LPC32XX_PERIPH_CLK); bsp_interrupt_initialize(); } -- cgit v1.2.3
